Abstract
AIMS The developmental origin of health and disease (DOHaD) theory postulates that poor nutrition during fetal life increases the risk of disease later in life. Excessive fructose intake has been associated with obesity, diabetes, and nonalcoholic fatty liver disease, and maternal fructose intake during pregnancy has been shown to affect offspring health. In this study, we investigated the effects of high maternal fructose intake on the liver stem/progenitor cells of offspring. MAIN METHOD A fructose-based DOHaD model was established using Sprague-Dawley rats. Small hepatocytes (SHs), which play an important role in liver development and regeneration, were isolated from the offspring of dams that were fed a high-fructose corn syrup (HFCS) diet. The gene expression and DNA methylation patterns were analyzed on postnatal day (PD) 21 and 60. KEY FINDINGS Maternal HFCS intake did not affect body weight or caloric intake, but differences in gene expression and DNA methylation patterns were observed in the SHs of offspring. Functional analysis revealed an association between metabolic processes and ion transport. SIGNIFICANCE These results suggest that maternal fructose intake affects DNA methylation and gene expression in the liver stem/progenitor cells of offspring. Furthermore, the prolonged retention of these changes in gene expression and DNA methylation in adulthood (PD 60) suggests that maternal fructose intake may exert lifelong effects. These findings provide insights into the DOHaD for liver-related disorders and highlight the importance of maternal nutrition for the health of the next generation.

Abstract
Mature hepatocytes (MHs) in an adult rodent liver are categorized into the following three subpopulations based on their proliferative capability: type I cells (MH-I), which are committed progenitor cells that possess a high growth capability and basal hepatocytic functions; type II cells (MH-II), which possess a limited proliferative capability; and type III cells (MH-III), which lose the ability to divide (replicative senescence) and reach the final differentiated state. These subpopulations may explain the liver's development and growth after birth. Generally, small-sized hepatocytes emerge in mammal livers. The cells are characterized by being morphologically identical to hepatocytes except for their size, which is substantially smaller than that of ordinary MHs. We initially discovered small hepatocytes (SHs) in the primary culture of rat hepatocytes. We believe that SHs are derived from MH-I and play a role as hepatocytic progenitors to supply MHs. The population of MH-I (SHs) is distributed in the whole lobules, a part of which possesses a self-renewal capability, and decreases with age. Conversely, injured livers of experimental models and clinical cases showed the emergence of SHs. Studies demonstrate the involvement of SHs in liver regeneration. SHs that appeared in the injured livers are not a pure population but a mixture of two distinct origins, MH-derived and hepatic-stem-cell-derived cells. The predominant cell-derived SHs depend on the proliferative capability of the remaining MHs after the injury. This review will focus on the SHs that appeared in the liver and discuss the significance of SHs in liver regeneration.

Abstract
BACKGROUND Small hepatocyte-like progenitor cells (SHPCs) are hepatocytic progenitor cells that transiently form clusters in rat livers treated with retrorsine (Ret) that underwent 70% partial hepatectomy (PH). We previously reported that transplantation of Thy1+ cells obtained from D-galactosamine-treated livers promotes SHPC expansion, thereby accelerating liver regeneration. Extracellular vesicles (EVs) secreted by Thy1+ cells induce sinusoidal endothelial cells (SECs) and Kupffer cells (KCs) to secrete IL17B and IL25, respectively, thereby activating SHPCs through IL17 receptor B (RB) signaling. This study aimed to identify the inducers of IL17RB signaling and growth factors for SHPC proliferation in EVs secreted by Thy1+ cells (Thy1-EVs). METHODS Thy1+ cells isolated from the livers of rats treated with D-galactosamine were cultured. Although some liver stem/progenitor cells (LSPCs) proliferated to form colonies, others remained as mesenchymal cells (MCs). Thy1-MCs or Thy1-LSPCs were transplanted into Ret/PH-treated livers to examine their effects on SHPCs. EVs were isolated from the conditioned medium (CM) of Thy1-MCs and Thy1-LSPCs. Small hepatocytes (SHs) isolated from adult rat livers were used to identify factors regulating cell growth in Thy1-EVs. RESULTS The size of SHPC clusters transplanted with Thy1-MCs was significantly larger than that of SHPC clusters transplanted with Thy1-LSPCs (p = 0.02). A comprehensive analysis of Thy1-MC-EVs revealed that miR-199a-5p, cytokine-induced neutrophil chemoattractant-2 (CINC-2), and monocyte chemotactic protein 1 (MCP-1) were candidates for promoting SHPC growth. Additionally, miR-199a-5p mimics promoted the growth of SHs (p = 0.02), whereas CINC-2 and MCP-1 did not. SECs treated with CINC-2 induced Il17b expression. KCs treated with Thy1-EVs induced the expression of CINC-2, Il25, and miR-199a-5p. CM derived from SECs treated with CINC-2 accelerated the growth of SHs (p = 0.03). Similarly, CM derived from KCs treated with Thy1-EVs and miR-199a-5p mimics accelerated the growth of SHs (p = 0.007). In addition, although miR-199a-overexpressing EVs could not enhance SHPC proliferation, transplantation of miR-199a-overexpressing Thy1-MCs could promote the expansion of SHPC clusters. CONCLUSION Thy1-MC transplantation may accelerate liver regeneration owing to SHPC expansion, which is induced by CINC-2/IL17RB signaling and miR-199a-5p via SEC and KC activation.

Abstract
Hepatic Stem/progenitor cells (HSPCs) have gained a large amount of interest for treating acute liver disease. However, the isolation and identification of HSPCs are unclear due to the lack of cell-specific surface markers. To isolate adult HSPCs, we used cell surface-marking antibodies, including CD49f and Sca-1. Two subsets of putative HSPCs, Lin-CD45-Sca-1-CD49f+ (CD49f+) and Lin-CD45-Sca-1+CD49f- (Sca-1+) cells, were isolated from adult mice liver by flow cytometry. Robust proliferative activity and clonogenic activity were found in both CD49f+ and Sca-1+ cells through colony-forming tests and cell cycle analyses. Immunofluorescence staining revealed that CD49f+ cells expressed ALB and CK-19 while Sca-1+ cells expressed only ALB, indicating that CD49f+ cells were bipotential and capable of differentiating into hepatocyte and cholangiocyte. Consequently, PAS stain showed that differentiated CD49f+ and Sca-1+ cells synthesised glycogen, indicating they could differentiate into functional hepatocytes. mRNA expression profile indicated that both CD49f+ and Sca-1+ cells showed differential expression of genes that are associated with liver progenitor function such as Sox9 and EpCam. Moreover, two subsets of putative HSPCs were activated by DDC and we found that their abundance and proliferation increased with age. In summary, we hypothesized that CD49f+ cells were a type of potential HSPCs and may be utilised for clinical stem cell therapy.

Abstract
Background Small hepatocyte-like progenitor cells (SHPCs) appear to form transient clusters in rat livers treated with retrorsine (Ret) and 70% partial hepatectomy (PH). We previously reported that the expansion of SHPCs was amplified in Ret/PH-treated rat livers transplanted with Thy1+ cells derived from d-galactosamine-treated injured livers. Extracellular vesicles (EVs) produced by hepatic Thy1+ donor cells activated SHPCs via interleukin (IL)-17 receptor B signaling. As bone marrow-derived mesenchymal cells (BM-MCs) also express Thy1, we aimed to determine whether BM-MCs could also promote the growth of SHPCs. Methods BM-MCs were isolated from dipeptidyl-peptidase IV (DPPIV)-positive rats. BM-MCs or BM-MC-derived EVs were administered to DPPIV-negative Ret/PH rat livers, and the growth and the characteristics of SHPC clusters were evaluated 14 days post-treatment. miRNA microarrays and cytokine arrays examined soluble factors within EVs. Small hepatocytes (SHs) isolated from an adult rat liver were used to identify factors enhancing hepatocytic progenitor cells growth. Results The recipient’s livers were enlarged at 2 weeks post-BM-MC transplantation. The number and the size of SHPCs increased remarkably in livers transplanted with BM-MCs. BM-MC-derived EVs also stimulated SHPC growth. Comprehensive analyses revealed that BM-MC-derived EVs contained miR-146a-5p, interleukin-6, and stem cell factor, which could enhance SHs’ proliferation. Administration of EVs derived from the miR-146a-5p-transfected BM-MCs to Ret/PH rat livers remarkably enhanced the expansion of SHPCs. Conclusions miR-146a-5p involved in EVs produced by BM-MCs may play a major role in accelerating liver regeneration by activating the intrinsic hepatocytic progenitor cells.

Abstract
In this study, we investigated how the ability of hepatocytic parental progenitor cells (HPPCs) to self‐renew can be maintained and how laminin (LN) isoforms play an important role in their self‐renewal and maturation. Hepatocytes isolated from adult rat livers were cultured on hyaluronic acid to form colonies consisting of CD44+ small hepatocytes, which could be passaged on dishes coated with Matrigel. When second‐passage cells were plated on Matrigel, LN111, or LN511, HPPCs appeared on Matrigel and LN111 but not on LN511. We identified two types of cells among the second‐passage cells: Small, round cells and large, flat ones were observed on Matrigel, whereas the former and latter ones were specifically attached on LN111 and LN511, respectively. We hypothesized that small and round cells are the origin of HPPC colonies, and the binding to LN111 could be key to maintaining their self‐renewal capability. Among the integrins involved in LN binding, integrins α3 and β1 were expressed in colonies on LN111 more than in those on LN511, whereas β4 was more strongly expressed in colonies on LN511. Integrin α3highα6β1high cells could form HPPC colonies on LN111 but not on LN511, whereas integrin α6β1low cells could not on either LN111 or LN511. In addition, neutralizing anti‐integrin β1 and anti‐LN111 antibodies inhibited the passaged cells’ ability to attach and form colonies on LN111 by HPPCs. Matrigel overlay induced second‐passage cells growing on LN111 to increase their expression of hepatic functional genes and to form 3‐dimensional colonies with bile canalicular networks, whereas such a shift was poorly induced when they were grown onLN511. Conclusion: These results suggest that the self‐renewal capability of HPPCs depends on LN111 through integrin β1 signaling.

Abstract
In this study, freshly isolated and cryopreserved cynomolgus monkey hepatocytes were seeded on Cell-able® plates with feeder cells to form spheroids and were cultured for 28 days. As a control, hepatocytes were also cultured with or without feeder cells on collagen-coated plates. We verified the mRNA expression levels of drug-metabolizing enzyme-related genes and the leakage of enzymes (AST, ALT, LDH, and γ-GTP) as indicators of cell survival. As a result, the patterns of target mRNA expression in fresh and cryopreserved hepatocytes were very similar during the culture period between culture methods. mRNA expression levels were highly maintained at day 28 using the 3D spheroid and co-culture methods, demonstrating that these methods are useful for maintenance of liver function. Leakage of AST and ALT was higher at day 3 but decreased at day 14. LDH was not detected, suggesting that the cell viability was also maintained during the culture period. Furthermore, the functional differences between fresh and cryopreserved hepatocytes were not clearly detected. The co-culture method was useful for long-term culture not requiring 3D structure, and the 3D spheroid culture method was effective as well. With these techniques, cynomolgus monkey hepatocytes are expected to exhibit smaller individual differences and high reproducibility.

Abstract
This protocol showed procedures to isolate and expand small hepatocytes (SHs), as hepatocytic progenitor cells, from a rat liver. SHs are identified as a subpopulation of mature hepatocytes in a healthy liver. SHs can proliferate to form colonies in serum-free medium on hyaluronic acid-coated dishes, of which cells show CD44 positivity (CD44+ SHs). CD44+ SHs can be separated and purified from colonies by using anti-CD44 antibodies after enzymatic dissociation. CD44+ SHs can proliferate to form colonies on Engelbreth-Holm-Swarm gel (EHS-gel)-coated dishes in the serum-free medium for a long period and subculture for several times. Even after the second passage, the cells possess characteristics of hepatocytes such as expression of albumin and HNF4α. In addition, when the cells are treated with EHS-gel, they can recover highly differentiated functions of hepatocytes such as glycogen production, CYP activity, and bile secretion.

Abstract
Rabbit mesenchymal stem cells (MSCs) are important seed cells in regenerative medicine research, particularly in translational research. In the current study, we showed that rabbit subchondral bone is a reliable source of MSCs. First, we harvested subchondral bone (SCB) from the rabbit knee-joint and initiated the MSC culture by cultivating enzyme-treated SCB. Adherent fibroblast-like cells that outgrew from SCB fulfill the common immuno-phenotypic criteria for defining MSCs, but with low contamination of CD45+ hematopoietic cells. Interestingly, differentiated SCB-MSCs expressed osteogenic and chondrogenic markers at significantly higher levels than those in bone marrow cell suspension-derived MSCs (BMS-MSCs) (P<0.05). No differences in the expression of adipogenic markers between SCB-MSC and BMS-MSC (P>0.05) were observed. Moreover, the results of the colony forming unit-fibroblast assay and sphere formation assay demonstrated that the SCB-MSCs had increased self-renewal potential. SCB-MSCs expressed higher levels of the stemness markers Nanog, OCT4, and Sox-2 compared to in BMS-MSCs (P<0.05). Furthermore, the results of both the CCK-8-based assay and CFSE dilution assay showed that SCB-MSCs exhibited enhanced proliferative capacity. In addition, SCB-MSCs exhibited higher phosphorylation of extracellular signal-related kinase/mitogen-activated protein kinase signaling, which is closely related to MSC proliferation. In conclusion, we identified SCB-MSCs as a novel stem cell population that met the requirements of MSCs; the unique properties of SCB-MSC are important for the potential treatment of tissue damage resulting from disease and trauma.
