Abstract
Purpose This study used a sciatic nerve injury rat model to investigate the short-term effects of a polyglycolic acid (PGA)-collagen tube for nerve injury in continuity. Materials and Methods Sixteen female Wistar rats (6-8 weeks) were used, and the left sciatic nerve was crushed with a Sugita aneurysm clip. Sciatic nerve model rats were randomly categorized into two groups (n = 8; control group, n = 8; nerve wrapping group). Then, we measured four sensory thresholds, magnetically stimulated the lumbar region to induce motor-evoked potentials (MEPs), and evaluated the sciatic nerve histopathologically. Results In the sensory thresholds, there were significant differences for the main effect in 250 and 2000 Hz stimulation (p = 0.048 and 0.006, respectively). Further, a significant difference was observed with 2000 Hz stimulation at 1 week (p = 0.003). In the heat stimulation, there were significant differences for the main effect in both weeks and groups (p = 0.0002 and 0.0185, respectively). The post-hoc test showed a significant difference between groups only in 2W (p = 0.0283). Three weeks after the surgery, both 2nd and 3rd MEPs waves-related latencies in the nerve wrapping group were significantly shorter than those in the control group (p = 0.0207 and 0.0271, respectively). Histological evaluation of the sciatic nerve revealed considerable differences in the number of axons between the two groups (p = 0.0352). Conclusion The short-term PGA-collagen tube nerve wrapping facilitated motor and sensory recovery from nerve degeneration in the sciatic nerve injury rat model.

Abstract
Background Interactions between adipocyte and breast cancer (BC) cells have yet to be fully elucidated. Here we investigated the prognostic impact of marginal adipose tissue invasion in both luminal breast cancer (HR+/HER2-) and triple-negative breast cancer (TNBC) (HR−/HER2-). Methods A total of 735 patients with early-stage invasive BC (1999–2014) were retrospectively registered. Median length of patient follow-up was 8.9 years. Survival curves were calculated using a Kaplan-Meier cumulative survival plot. The prognostic difference between two groups were assessed by the univariate Cox-proportional hazard regression model. Results Patients with adipose tissue invasion (n = 614) had a significantly poorer prognosis than those without adipose tissue invasion (n = 121) in overall survival (OS) (hazard ratio, 2.1; 95% Confidence interval [CI], 1.1 to 4.0; P = 0.025). While a poorer prognosis was observed in TNBC (n = 137) than in luminal BC patients (n = 496) (hazard ratio, 0.45; 95% CI, 0.30 to 0.68, P < 0.001), this aggressive nature of TNBC was noted in node-positive disease (hazard ratio, 0.3; 95% CI, 0.18 to 0.5, P < 0.001) but not in node-negative disease (hazard ratio, 0.78; 95% CI, 0.39 to 1.55, P = 0.472), and also noted in adipose tissue invasion-positive patients (hazard ratio, 0.4; 95% CI, 0.26 to 0.6, P < 0.001) but not in adipose tissue invasion-negative patients (hazard ratio, 0.73; 95% CI, 0.16 to 3.24, P = 0.675). In addition, although patients suffering from TNBC with adipose tissue invasion had a poorer outcome than those without adipose tissue invasion (hazard ratio, 3.63; 95% CI, 1.11 to 11.84; P = 0.033), the difference was not observed in luminal BC (hazard ratio, 1.75; 95% CI, 0.64 to 4.82; P = 0.277). Conclusions Adipose tissue invasion was correlated with poor survival in TNBC. Cancer cell invasion into local fat may be a first step on cancer progression and systemic disease in TNBC.

Abstract
Lanthanum (La) carbonate (LC) is one of the most potent phosphate binders that prevents the elevation of serum phosphate levels in patients with end-stage renal diseases undergoing dialysis. LC binds strongly to dietary phosphate and forms insoluble complexes that pass through the gastrointestinal tract. La deposition in patients treated with LC is a recently documented finding particularly observed in gastric mucosa. We herein describe the detailed gastric mucosal lesions in 45 LC-treated patients and address the potential underlying pathologic mechanism using oral LC administration in rats. Microscopically, La deposition, as shown by subepithelial collections of plump eosinophilic histiocytes or small foreign body granulomas containing coarse granular or amorphous inclusion bodies, was found in the gastric mucosa of 44 (97.8%) of the 45 dialysis patients in the study cohort, which was most frequently associated with foveolar hyperplasia (37.8%). Using oral administration of rats with 1000 mg/day LC for 2 or more weeks, La deposition was consistently detectable in the gastric mucosa but not in other organs examined. In addition, various histologic alterations such as glandular atrophy, stromal fibrosis, proliferation of mucous neck cells, intestinal metaplasia, squamous cell papilloma, erosion, and ulcer were demonstrated in the rat model. Thus, orally administered LC can induce mucosal injury, designated here as La gastropathy, which may alter the local environment and result in La deposition in the gastric mucosa, thereby potentially inducing abnormal cell proliferation or neoplastic lesions.

Abstract
Prominent cyst formation is an unusual feature of liposarcoma. We report here a case of dedifferentiated liposarcoma with huge cystic change without preoperative chemo- or radiation therapy. The lesion arose in the retroperitoneum juxtaposed to the right kidney of a 67-year-old woman. She underwent a surgical removal of the retroperitoneal cyst. The cystic tumor contained 1600 mL of old bloody fluid, and its wall was composed of edematous, inflamed or sclerosing fibrous tissue with fatty tissue containing abundant atypical stromal cells, which were immunohistochemically positive for MDM2 and CDK4, and demonstrated MDM2 gene amplification by fluorescence in situ hybridization. The wall was contiguous to an atypical lipomatous nodule located in the mesentery. The following surgical specimens of the right hemicolectomy and right nephrectomy revealed atypical cells infiltrating into the subserosa of the colon and the perirenal fat tissue or that in the renal sinus. This case indicates that well differentiated or dedifferentiated liposarcoma should be also considered as a differential diagnosis of perirenal cystic mass.

Abstract
While parenchymal metastases are common in solid systemic cancers, subependymal metastases are rare. Approximately half of the reported cases of intraventricular metastases originate from renal carcinoma. A 65-year-old man presented with general fatigue, appetite loss, nausea, and disorientation. Radiological examination revealed diffuse periventricular tumors. The patient underwent an open biopsy via right frontotemporal craniotomy. The patient was diagnosed with metastatic small cell lung carcinoma after histopathological examination. Although subependymal metastases from solid systemic cancer are very rare, this ventricular wall abnormality in the cancer patients must not be overlooked. Many small subependymal metastases might be missed on routine examination.

Abstract
A 68-year-old man presented with abnormal behavior and Todd's paralysis on the right side after having taken a bath. Computed tomography and magnetic resonance imaging revealed a tumor mimicking convexity meningioma that had a perifocal edema, although its mass was not very large. The patient underwent surgery, and full recovery was achieved following a total removal of the lesion. Pathohistological examination demonstrated an intermediate type of Castleman's disease. The final diagnosis was intracranial localized Castleman's disease because the results of the full physical examination and laboratory analyses were normal. Castleman's disease is a rare lymphoproliferative disorder of unknown etiology. Moreover, intracranial involvement is very rare. In cases of intracranial meningeal tumors with perifocal edema, we should take this disease into consideration in the differential diagnosis.

Abstract
Lanthanum carbonate (LC) is one of the most potent phosphate binders currently used to reduce serum phosphate levels in dialysis patients with end-stage renal disease (ESRD). LC forms insoluble complexes with dietary phosphate that pass through the gastrointestinal (GI) tract with little absorption. GI lesions due to lanthanum deposition in biopsy specimens or those in endoscopic submucosal dissection (ESD) in dialysis patients have been recently identified. Here, we describe more detailed histopathological findings in the gastroduodenal mucosa and regional lymph nodes in three patients with gastric cancer. Three patients with ESRD, two elderly women and one man, underwent dialysis and were treated with LC for 3-36 months. The patients underwent laparoscopic distal gastrectomy and lymph node dissection due to gastric cancer. Many subepithelial histiocyte aggregates or small foreign body granulomas, which contained gray or brown pigments or crystal-like structures, were mostly present in non-neoplastic areas of the upper GI. Lanthanum accumulation was noted in the duodenal mucosa and the antral and body mucosae of the gastric lesser curvature. Lanthanum was also deposited in the regional lymph nodes of the three patients. Electron microscopy with energy dispersive X-ray spectroscopy confirmed lanthanum and phosphorus deposits in histiocytes. Long-term prognosis of patients and the excretion or the metabolic pathway of accumulated lanthanum remain unclear.

Abstract
Esophageal squamous cell carcinoma (ESCC) develops within the squamous epithelial layer and invades the submucosa to the subadventitia that has adipose tissue (AT). AT seems critical to ESCC progression, but the underlying mechanism is unknown. We aimed to address the association between ESCC and AT in vitro. ESCC cells were cultured on rat or human subcutaneous AT-embedded or -non-embedded collagen gel. AT promoted the growth of ESCC cells and inhibited their apoptosis. AT promoted the expression of the squamous differentiation marker involucrin in ESCC cells. AT accelerated the expression of invasion-related factors in poorly differentiated ESCC cells only. AT promoted the expression of phosphorylated-insulin-like growth factor-1 receptor in ESCC cells, whereas it inhibited that of the human epidermal growth factor receptor 2. Insulin-like growth factor-1, but not leptin, adiponectin, or resistin, promoted and inhibited the growth and apoptosis of ESCC cells, respectively. In turn, ESCC cells decreased the production of these adipokines in AT and the number of preadipocytes and mesenchymal stem cell-like cells, which developed from AT. These results suggest that i) AT may influence the progression of ESCC with increased growth or invasion and decreased apoptosis through insulin-like growth factor-1/insulin-like growth factor-1 receptor signaling, ii) AT may affect human epidermal growth factor receptor 2-targeted therapy; and iii) the cancer cells may affect adipokine production in AT.

Abstract
BACKGROUND Small caliber vascular prostheses are not clinically available because synthetic vascular prostheses lack endothelial cells which modulate platelet activation, leukocyte adhesion, thrombosis, and the regulation of vasomotor tone by the production of vasoactive substances. We developed a novel method to create scaffold-free tubular tissue from multicellular spheroids (MCS) using a "Bio-3D printer"-based system. This system enables the creation of pre-designed three-dimensional structures using a computer controlled robotics system. With this system, we created a tubular structure and studied its biological features. METHODS AND RESULTS Using a "Bio-3D printer," we made scaffold-free tubular tissues (inner diameter of 1.5 mm) from a total of 500 MCSs (2.5× 104 cells per one MCS) composed of human umbilical vein endothelial cells (40%), human aortic smooth muscle cells (10%), and normal human dermal fibroblasts (50%). The tubular tissues were cultured in a perfusion system and implanted into the abdominal aortas of F344 nude rats. We assessed the flow by ultrasonography and performed histological examinations on the second (n = 5) and fifth (n = 5) day after implantation. All grafts were patent and remodeling of the tubular tissues (enlargement of the lumen area and thinning of the wall) was observed. A layer of endothelial cells was confirmed five days after implantation. CONCLUSIONS The scaffold-free tubular tissues made of MCS using a Bio-3D printer underwent remodeling and endothelialization. Further studies are warranted to elucidate the underlying mechanism of endothelialization and its function, as well as the long-term results.

Abstract
Deregulated phosphate homeostasis can lead to a wide range of disorders, including myopathy, cardiac dysfunction, and skeletal abnormalities. Therefore, characterization of the molecular regulation of phosphate metabolism is of pathophysiological and clinical significance. Hyp mouse is the model for human X-linked hypophosphatemia which is due to mutations that inactivate the endopeptidases of the X chromosome (PHEX). PHEX inactivation leads to increased serum levels of fibroblast growth factor 23 (FGF23), a phosphaturic hormone that induces excessive renal phosphate excretion and severe hypophosphatemia. The expression of WNT signaling components is increased in Hyp mice. To determine the potential role of WNT signaling in FGF23-mediated hypophosphatemia, we cross-bred Hyp mice with mice deficient in the WNT coreceptor low-density lipoprotein receptor-related protein 6 (Lrp6) to generate Hyp and Lrp6 double mutant mice (Hyp/Lrp6). Like Hyp mice, Hyp/Lrp6 double mutants maintained high serum levels of FGF23, and accordingly exhibited hypophosphatemia to the same degree as the Hyp mice did, indicating that genetically reducing WNT signaling does not impact FGF23-induced phosphaturia. Moreover, similar to Hyp mice, the Hyp/Lrp6 double mutants also exhibited reduced mineralization of the bone, further supporting that reduced WNT signaling does not affect the chronic phosphate wasting caused by excess FGF23 in these mice. In further support of our finding, injection of bioactive FGF23 protein into Lrp6 mutant mice reduced serum phosphate levels to a similar degree as FGF23 injection into wild-type mice. Our in vivo studies provide genetic and pharmacological evidence for a WNT-independent function of FGF23 in the regulation of phosphate homeostasis.

Abstract
Systemic adipose tissue is involved in the pathophysiology of obesity-associated liver diseases. However, a method has not been established for analyzing the direct interaction between adipose tissue and hepatocytes. We describe a useful three-dimensional model comprising a collagen gel coculture system in which HepG2 hepatocytes are cultured on a gel layer with visceral adipose tissue fragments (VAT) or subcutaneous tissue samples (SAT). Male adipose tissues were obtained from 5-week-old Wistar rats and human autopsy cases. Cellular behavior was analyzed by electron microscopy, immunohistochemistry, Western blot, real-time reverse transcription plus the polymerase chain reaction and enzyme-linked immunosorbent assay. VAT significantly promoted lipid accumulation and apoptosis in HepG2 cells and suppressed their growth and differentiation compared with SAT. VAT produced higher concentrations of fatty acids (palmitate, oleate, linoleate) than SAT. HepG2 cells significantly decreased the production of these fatty acids in VAT. Only HepG2 cells treated with 250 μM palmitate replicated VAT-induced apoptosis. Neither VAT nor SAT affected lipotoxicity-associated signals of nuclear factor kappa B, c-Jun N-terminal kinase and inositol requiring enzyme-1α in HepG2 cells. HepG2 cells never affected adiponectin, leptin, or resistin production in VAT and SAT. The data indicate that our model actively creates adipose tissue and HepG2 hepatocyte interactions, suggesting that (1) VAT plays more critical roles in hepatocyte lipotoxicity than SAT; (2) palmitate but not adipokines, is partly involved in the mechanisms of VAT-induced lipotoxicity; (3) HepG2 cells might inhibit fatty acid production in VAT to protect themselves against lipotoxicity. Our model should serve in studies of interactions between adipose tissue and hepatocytes and of the mechanisms in obesity-related lipotoxicity and liver diseases.

Abstract
Osteoblasts are believed to differentiate into osteocytes, becoming embedded in bone, or to undergo apoptosis after the bone formation phase. The regulation of this terminal differentiation seems to be critical for bone homeostasis. However the mechanism remains unclear and there is no assay system currently available to analyze this process. To address this issue, we developed a new model in which osteoblasts are cultured on a type I collagen gel layer with osteogenic supplements β-glycerophosphate and ascorbic acid. Cellular behavior was analyzed by electron microscopy, immunohistochemistry and real-time RT-PCR. Osteoblasts gradually migrated into the gel, produced collagen fibrils, and differentiated to osteocytic cells with bone lacunae- and canaliculi-like mineralization. Osteocalcin, DMP-1 and SOST protein expression was mainly expressed in the migrated cells within the mid-layer of the gel. Osteoblastic (ALP and osteocalcin) and osteocytic (PHEX, DMP-1 and SOST) mRNA expression was significantly increased compared with those of the cells cultured on plastic dishes alone after 21 days. The number of TUNEL-positive apoptotic cells gradually increased, reaching a maximum at 28 days. The cells were distributed at the surface and in the mid-layer of the gel at 7 days and after 14 days of culture, respectively. These data indicate that our model reproduces transition from osteoblasts to osteocytes, suggesting the following: 1) migration of osteoblasts into collagen gel may play a critical role in osteocytic differentiation; and 2) spatiotemporal gene expression and apoptosis may be involved in the terminal differentiation of osteoblasts. Our model will make it possible to study the mechanism of transition from osteoblast to osteocyte, and both cell type-related diseases including osteoporosis and osteonecrosis.

Abstract
Adipose tissue consists of mature adipocytes, preadipocytes and mesenchymal stem cells (MSCs), but a culture system for analyzing their cell types within the tissue has not been established. We have recently developed "adipose tissue-organotypic culture system" that maintains unilocular structure, proliferative ability and functions of mature adipocytes for a long term, using three-dimensional collagen gel culture of the tissue fragments. In this system, both preadipocytes and MSCs regenerate actively at the peripheral zone of the fragments. Our method will open up a new way for studying both multiple cell types within adipose tissue and the cell-based mechanisms of obesity and metabolic syndrome. Thus, it seems to be a promising model for investigating adipose tissue biology and regeneration. In this article, we introduce adipose tissue-organotypic culture, and propose two theories regarding the mechanism of tissue regeneration that occurs specifically at peripheral zone of tissue fragments in vitro.

Abstract
Encapsulating peritoneal sclerosis (EPS) often develops after transfer to hemodialysis and transplantation. Both termination of peritoneal dialysis (PD) and transplantation-related factors are risks implicated in post-PD development of EPS, but the precise mechanism of this late-onset peritoneal fibrosis remains to be elucidated. We previously demonstrated that fluid flow stress induced mesothelial proliferation and epithelial-mesenchymal transition via mitogen-activated protein kinase (MAPK) signaling. Therefore, we speculated that the prolonged bioactive effect of fluid flow stress may affect mesothelial cell kinetics after cessation of fluid streaming. To investigate how long mesothelial cells stay under the bioactive effect brought on by fluid flow stress after removal of the stress, we initially cultured mesothelial cells under fluid flow stress and then cultured the cells under static conditions. Mesothelial cells exposed to fluid flow stress for a certain time showed significantly high proliferative activity compared with static conditions after stoppage of fluid streaming. The expression levels of protein phosphatase 2A, which dephosphorylates MAPK, in mesothelial cells changed with time and showed a biphasic pattern that was dependent on the duration of exposure to fluid flow stress. There were no differences in the fluid flow stress-related bioactive effects on mesothelial cells once a certain time had passed. The present findings show that fluid flow stress exerts a prolonged bioactive effect on mesothelial cells after termination of fluid streaming. These findings support the hypothesis that a history of PD for a certain period could serve as a trigger of EPS after stoppage of PD.

Abstract
The thyroid is composed of thyroid follicles supported by extracellular matrix, capillary network, and stromal cell types such as fibroblasts. The follicles consist of thyrocytes and C cells. In this microenvironment, thyrocytes are highly integrated in their specific structural and functional polarization, but monolayer and floating cultures cannot allow thyrocytes to organize the follicles with such polarity. In contrast, three-dimensional (3-D) collagen gel culture enables thyrocytes to form 3-D follicles with normal polarity. However, these systems never reconstruct the follicles consisting of both thyrocytes and C cells. Thyroid tissue-organotypic culture retains 3-D follicles with both thyrocytes and C cells. To create more appropriate experimental models, we here characterize four culture systems above and then introduce the models for studying thyroid biology and disorders. Finally, we propose a new approach to the cell type-specific culture systems on the basis of in vivo microenvironments of various cell types.

Abstract
BACKGROUND Peritoneal fibrosis is an essential precursor condition to the development of encapsulating peritoneal sclerosis (EPS). This serious complication leads to a high mortality rate in peritoneal dialysis (PD) patients. Although several factors, including highly concentrated glucose in the dialysis solution, are believed to be potent agents for peritoneal fibrosis, the underlying mechanism remains unclear. During PD, the dialysis solution continuously generates fluid flow stress to the peritoneum under peristalsis and body motion. Fluid flow stress has been implicated as playing a critical role in the physiologic responses of many cell types. We therefore hypothesized that fluid flow stress may be involved in the pathogenesis of peritoneal fibrosis leading to EPS. METHODS To generate fluid flow stress, culture containers were placed on a rotatory shaker in a thermostatic chamber. In this system, the shaker rotated at a speed of 25 rpm with a radius of 1.5 cm. Mesothelial cells were cultured in low-glucose (1000 mg/L) or high-glucose (4500 mg/L) complete medium with and without flow stress. RESULTS Fluid flow stress promoted hyperplasia and epithelial-mesenchymal transition (EMT) of mesothelial cells independent of glucose concentration. Fluid flow stress inhibited expression of ERK (extracellular signal-regulated kinase) and p38 MAPK (mitogen-activated protein kinase) in mesothelial cells. Administration of ERK and p38 MAPK inhibitors replicated the stress-induced morphology of mesothelial cells. CONCLUSIONS The present data indicate that fluid flow stress promotes hyperplasia and EMT of mesothelial cells via the MAPK axis, suggesting that fluid flow stress may be involved in the pathogenesis of peritoneal fibrosis.

Abstract
The heart has epicardial adipose tissue that produces adipokines and mesenchymal stem cells. Systemic adipose tissue is involved in the pathophysiology of obesity-related heart diseases. However, the method for analyzing the direct interaction between adipose tissue and cardiomyocytes has not been established. Here we show the novel model, using collagen gel coculture of adipose tissue fragments (ATFs) and HL-1 cardiomyocytes, and electron microscopy, immunohistochemistry, real-time RT-PCR, and ELISA. HL-1 cells formed a stratified layer on ATF-nonembedded gel, whereas they formed almost a monolayer on ATF-embedded gel. ATFs promoted the apoptosis, lipid accumulation, and fatty acid transport protein (FATP) expression of FATP4 and CD36 in HL-1 cells, whereas ATFs inhibited the growth and mRNA expression of myosin, troponin T, and atrial natriuretic peptide. Treatment of leptin (100 ng/ml) and adiponectin (10 μg/ml) neither replicated nor abolished the ATF-induced morphology of HL-1 cells, whereas that of FATP4 and CD36 antibodies (25 μg/ml) never abolished it. HL-1 cells prohibited the development of CD44+/CD105+ mesenchymal stem cell-like cells and lipid-laden preadipocytes from ATFs. HL-1 cells increased the production of adiponectin in ATFs, whereas they decreased that of leptin. The data indicate that our model actively creates adipose tissue-HL-1 cardiomyocyte interaction, suggesting first that ATFs may be related to the lipotoxiciy of HL-1 cells via unknown factors plus FATP4 and CD36 and second that HL-1 cells may help to retain the static state of ATFs, affecting adipokine secretion. Our model will serve to study adipose tissue-cardiomyocyte interaction and mechanisms of obesity-related lipotoxicity and heart diseases.

Abstract
Adipose tissue exists in the gastric submucosa and subserosa. Thus, adipose tissue stromal cells (ATSCs), which include mesenchymal stem cells (MSCs), seem critical for the progression of gastric cancer but their interaction with the cancer cells is unknown. We demonstrated an interaction between these cells, using immunohistochemistry, Western blot and the collagen gel invasion assay system, in which the adenocarcinoma cells (well and poorly differentiated types, MKN28 and MKN45, respectively) were cultured on a ATSC-embedded or ATSC-non-embedded gel. ATSCs promoted the expression of the growth marker, proliferation cell nuclear antigen but inhibited that of the apoptosis marker, single-stranded DNA, in the cancer cell types. ATSCs accelerated the invasion of only MKN28 into the gel and promoted the expression of mitogen-activated protein kinase (MAPK, pERK-1/2) but decreased that of the molecularly targeted protein, HER2, in the cancer cells. ATSCs did not affect the expression of the prostaglandin biosynthetic enzyme cyclooxgenase-2 (COX-2) in the cancer cells. The COX-2 inhibitor celecoxib did not affect the morphology or invasion of the cancer cells. The cancer cell types in turn promoted the display of the myofibroblast marker, α-smooth muscle actin, whereas they decreased that of some MSC markers, e.g., CD44 and CD105, in ATSCs. The data suggest that (1) ATSCs influence the progression of gastric cancer by increasing their growth/invasion and decreasing their apoptosis through MAPK activation in a COX-2-independent way; (2) ATSCs adversely affect HER2-targeted therapy; (3) the cancer cells induce the cancer-associated myofibroblast phenotype in ATSCs.

Abstract
Adipokine-producing fatty tissues, composed of preadipocytes, adipocytes, and mesenchymal stem cells, surround the kidney. To study the interaction between renal tubular cells and adipose tissue, we cocultured adipose tissue fragments and MDCK cells. MDCK cells in the coculture showed a taller columnar shape with improved organization of their microvilli and basal lamina than that seen in MDCK cell monoculture. The adipose tissue-induced change in morphology was replicated when we added leptin to MDCK cells cultured alone. Adiponectin abolished the leptin effect. Adipose tissue fragments inhibited MDCK cell division and also the formation of single-stranded DNA, an indicator of apoptosis. The fragments promoted the expression of polarity-associated proteins, including the tight junction molecules, ZO-1, atypical protein kinase C, and Cdc42. Further, the fragments also accelerated the expression of pendrin, the chloride/iodide transporter in the MDCK cells. In turn, MDCK cells decreased the number of preadipocytes and CD44+/CD105+ mesenchymal stem cells in the fragments, and promoted adiponectin production from the fragments. Thus, our study shows that adipose tissue fragments promote the hypertrophy, polarization, and differentiation of MDCK cells by attenuating their growth and apoptosis through opposing endocrine or paracrine effects of leptin and adiponectin. Further, MDCK cells inhibit the regeneration of preadipocytes and mesenchymal stem cells in adipose tissue.

Abstract
Achilles tendon ruptures rarely occur in patients over 80 years of age. However, it is unclear what treatment, surgical or conservative, is suitable for such an Achilles tendon rupture in the elderly. In addition, the clinical results of an Achilles tendon rupture in the elderly are disappointing. We report here the case of a subcutaneous Achilles tendon rupture in an eighty-year-old, healthy female, who returned to her previous level of activity following surgical treatment. Additional case reports of other instances of successful treatment are needed to help establish the optimal treatment protocol for an Achilles tendon rupture in the elderly.

Abstract
The air-liquid interface (ALI) is a common microenvironment of the skin, but it is unknown whether the ALI affects melanoma cell behaviors. Using a collagen gel invasion assay, immunohistochemistry, and Western blots, here we show that melanoma cell proliferation in cultures with an ALI is higher than melanoma cell proliferation in submerged cultures. Bromodeoxyuridine (BrdU) uptake, an indicator of cell proliferation, of melanoma cells at the ALI was about 3 times that of submerged cells, while ALI and submerged melanoma cells had similar levels of single-stranded DNA (a marker of apoptosis). The ALI enhanced the expression of Raf-1, MEK-1 and pERK-1/2 components of the mitogen-activated protein kinase (MAPK) cascade, in cells more than the submerged condition did. The increases in BrdU uptake and pERK-1/2 expression promoted by ALI was abolished by the MEK inhibitor, PD-98059. ALI-treated and submerged melanoma cells did not infiltrate into the collagen gel, and they showed no significant difference in the expression of the invasion- and motility-related molecules, matrix metalloproteinase-1 and -9, laminin 5, and filamin A. Our data indicate that the ALI, a skin microenvironment, accelerates the growth, but not the apoptosis or invasion, of melanoma cells through MAPK activation.

Abstract
BACKGROUND Merkel cells (MCs) exist in the epidermal basal layer, in contact with keratinocytes. This direct contact seems critical for maintaining MCs in vitro. OBJECTIVES To estimate the effects of nerve cells on the maintenance of MCs within epidermal sheets in a new organotypic culture system of MCs. METHODS We developed a new organotypic culture system of MCs, using MC-containing epidermal sheets embedded in collagen gel. To estimate the effects of nerve cells on the maintenance of MCs within the epidermal sheets, we cocultured nerve cells and MC-containing epidermal sheets. In these culture assemblies, cellular behaviour was analysed by histochemistry, immunohistochemistry, electron microscopy and enzyme-linked immunosorbent assay. RESULTS This culture, even in the absence of neurotrophin (NT)-3 and nerve growth factor (NGF) (which are crucial for MC biology), retained cytokeratin (CK)-20-positive and neuroendocrine granule-containing MCs within the sheets for over 2 weeks. Coculture of MCs with PC-12 nerve cells significantly increased the number of MCs within the epidermal sheets, and the keratinocytes had almost identical expression levels of CK1, CK10, CK14 and the progenitor marker p63 to those produced by keratinocytes in vivo. Uptake of the growth marker bromodeoxyuridine by MCs and levels of NT-3 and NGF in the culture supernatants were undetectable in this system, regardless of the presence or absence of PC-12. CONCLUSIONS The data suggest, first, that direct contact between MCs and keratinocytes may be critical for retaining MCs in vitro; second, that nerve cell-affected maintenance of keratinocyte differentiation, but not NT-3 and NGF, may contribute to MC maintenance; and third, that MCs are not able to grow, at least in our system. Our method would be useful for studying MC biology.

Abstract
Adipose tissue that consists of mature and immature adipocytes is suggested to contain mesenchymal stem cells (MSCs), but a culture system for analyzing their cell types within the tissue has not been established. Here we show that three-dimensional collagen gel culture of rat sc adipose tissue fragments maintained viable mature adipocytes for a long term, producing immature adipocytes and MSC-like cells from the fragments, using immunohistochemistry, ELISA, and real time RT-PCR. Bromodeoxyuridine uptake of mature adipocytes was detected. Adiponectin and leptin, and adipocyte-specific genes of adiponectin, leptin, and PPAR-gamma were detected in culture assembly, whereas the lipogenesis factor insulin (20 mU/ml) and inflammation-related agent TNF-alpha (2 nm) increased and decreased, respectively, all of their displays. Both spindle-shaped cell types with oil red O-positive lipid droplets and those with expression of MSC markers (CD105 and CD44) developed around the fragments. The data indicate that adipose tissue-organotypic culture retains unilocular structure, proliferative ability, and some functions of mature adipocytes, generating both immature adipocytes and CD105+/CD44+ MSC-like cells. This suggests that our method will open up a new way for studying both multiple cell types within adipose tissue and the cell-based mechanisms of obesity and metabolic syndrome.

Abstract
This case report showed a laterally spreading tumor treated by endoscopic mucosal resection that developed as an advanced colon cancer. A 74-year-old female was visited to treat a colon tumor that was pointed out at another hospital. Total colonoscopy revealed a laterally spreading tumor (LST) 25 mm in diameter in the cecum. The lesion was diagnosed as homogenous granular type LST (G-type LST) and treated by endoscopic piecemeal mucosal resection in January 2004. A tumor was recognized by follow-up endoscopic examination in April 2006. The scar of endoscopic piecemeal mucosal resection had developed to advanced colon cancer and was treated by laparoscopy-associated ileocecal resection with D3 lymph node resection. Previous reports indicated that G-type LST in the colon could be treated by piecemeal resection, but this report suggests that G-type LST resected by piecemeal endoscopic mucosal resection might develop to advanced colon cancer.

Abstract
The distribution of neuronal-constitutive nitric oxide synthase (ncNOs)-positive nerve fibres was compared immunohistochemically, and the effect of NOs inhibitor and NO scavenger on the secretory response was compared functionally, in the two glands. Numerous ncNOs-positive fibres were distributed around acini in the submandibular gland but scarcely any around acini in the sublingual gland. Within the submandibular ganglion (parasympathetic), the nerve-cell bodies were strongly positive. Within the superior cervical ganglion (sympathetic), the nerve-cell bodies were negative, although some positive nerve fibres were observed. The secretory responses to the electrical stimulation of the chorda were significantly reduced by the NOs inhibitor, N(G)-nitro-L-arginine methyl ester (L-NAME, 10(-9)-10(-3) M) in a dose-dependent manner. The NO scavenger, 2-(4-carboxyphenyl)4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide (carboxy-PTIO) also reduced the chorda-evoked secretion (10(-9)-10(-6) M). The submandibular secretions evoked by stimulation of the superior cervical ganglion were not affected by L-NAME or carboxy-PTIO. In the sublingual gland, neither L-NAME nor carboxy-PTIO affected chorda-evoked salivary secretion. The histochemical and functional results both suggest that NO plays an excitatory role in the regulation of parasympathetic nerve-induced salivary secretion in the rat submandibular gland, but not in the sublingual gland.

Abstract
We examined the relationship between E-cadherin (E-CD), protein kinase C (PKC) and assembly of the tight junction (Tj) in rat submandibular gland acinar cells. The junctional complex of the acinar cells was double-labeled with anti-ZO-1 antibody and anti-E-CD antibody. When Ringer's solution was intraductally injected into the main duct, ZO-1 labels were highly concentrated at the Tj zone, and the adherens junction (Aj) was exclusively labeled by E-CD. In addition, the Tj was impermeable to microperoxidase. Neither intraductal injection of anti-E-CD antibody solution nor infusion of carbachol produced labels for ZO-1 at the Tj zone, although these proteins were occasionally intermixed at the Aj zone. In these cases, the Tj was permeable to microperoxidase. Intraductal injection of anti-E-CD antibody solution with PKC agonist, resulted in a reduction of E-CD labels in the Aj zone, while the ZO-1 was labeled exclusively in the Tj zone. In this case, Tj was impermeable to microperoxidase. These results suggest that E-CD plays a major role in mediating intercellular physical adhesion, and that PKC may be active in signaling the pathway activated by E-CD-mediated cell-cell adhesion.

Abstract
The permeability of these junctions from the interstitium to the lumen was examined by using an ultrastructural tracer, microperoxidase, in conjunction with electron microscopy. In the resting gland, the reaction product of microperoxidase was seen in the interstitial and intercellular spaces, but not within acinar lumina; thus the tight junction was impermeable to microperoxidase (junction closed). Intraductal injection of hypertonic sucrose solution (1000 mOsm; 30 microliters) caused a sustained elevation of the luminal pressure, indicating osmotic water flow into the lumen due to the presence of a hypertonic solution. In this gland no opening of the tight junctions was observed. In the chorda-stimulated gland, microperoxidase entered the lumen through the tight junctions, that is, they became permeable to microperoxidase (junction open). These findings suggest that chorda stimulation opens the acinar tight junctions and that the paracellular secretory pathway may be involved in the secretion of small molecules and water from the submandibular acini.

Abstract
We sought to determine the effect of substance P salivary stimulation on both electrical charges and cellular permeability in the tight junctions of rat submandibular gland cells. Microperoxidase (1,900 daltons) was used as a tracer. It was administered by close-arterial infusion via the glandular arteries, and secretory routes of acinar cells in the gland were determined cytochemically. In the resting gland, microperoxidase reaction product filled the lateral intercellular spaces up to the tight junctions, but did not penetrate them. In the substance P-stimulated gland, microperoxidase reaction product was present within tight junctions and the lumen. Both distribution and mobility of anionic sites on the surface of the submandibular gland cells were studied utilizing multivalent ligand, ruthenium red and cationized ferritin as probes. In the resting gland, ruthenium red deposits were located uniformly in all areas of the basal membrane and intercellular spaces except for the tight junctional region of acinar and ductal cells. In substance P-stimulated gland, ruthenium red deposits were present in the tight junctional region and, to a lesser extent, in the intercellular spaces. Electrical charges of the tight junctions area of the lateral plasma membrane were studied using intraductal injection of cationized ferritin. In the resting gland, cationized ferritin probe was present in the intercellular spaces and was bound weakly in the tight junctional region. In the substance P-stimulated gland, cationized ferritin was firmly adherent to the tight junctional region.

Abstract
We investigated the effect of sympathetic agonists, parasympathetic muscarinic agonists and substance P on depletion of secretory granules in acinar cells of rat von Ebner's gland. Drugs were injected intraperitoneally at several different concentrations. Antagonists were given 15 minutes before injection of the agonist, and the extent of depletion of secretory granules in glandular acini was calculated using a computerized color image analyzer. The specific alpha 2-sympathetic agonist clonidine and the beta 1-sympathetic agonist dobutamine produced a depletion of secretory granules. When combined with injections of the alpha 2-sympathetic antagonist yohimbine and the beta 1-sympathetic antagonist acebutolol, depletion of secretory granules was blocked. The parasympathetic muscarinic agonist carbachol also produced a depletion of secretory granules. QNB blocked the depletion caused by carbachol, while atropine partially inhibited depletion. The specific M1-muscarinic agonist McN-A-343 caused some depletion, although there was no significant differences between it and the control. Complete depletion of the secretory granules was achieved by carbachol stimulation superimposed on substance P stimulation. We concluded that the activation of the sympathetic alpha 2- and beta 1-receptors, as well as the M2 (M2 beta)-muscarinic and substance P receptors, results in degranulation of acinar cells in von Ebner's gland of the rat.

Abstract
The damage caused to rat submandibular glands by intraductal injection was examined. When a small volume of isotonic saline was injected, even if salivation was not influenced, salivary composition was greatly affected because the intercellular junctions of the duct cells were damaged. Intraductal injections of hyperosmotic solutions or highly viscous liquids were more effective in damaging intercellular junctions. When interpreting the significance of a salivary composition in clinical diagnosis, it is necessary to consider the sialographic damage which might influence the salivary composition.
