Abstract
This review aims to describe the most recent achievements and provide an insight into cartilage engineering and strategies to restore the cartilage defects. Here, we discuss cell types, biomaterials, and biochemical factors applied to form cartilage tissue equivalents and update the status of fabrication techniques, which are used at all stages of engineering the cartilage. The actualized concept to improve the cartilage tissue restoration is based on applying personalized products fabricated using a full cycle platform: a bioprinter, a bioink consisted of ECM-embedded autologous cell aggregates, and a bioreactor. Moreover, in situ platforms can help to skip some steps and enable adjusting the newly formed tissue in the place during the operation. Only some achievements described have passed first stages of clinical translation; nevertheless, the number of their preclinical and clinical trials is expected to grow in the nearest future.

Local and Remote Effects of Mesenchymal Stem Cell Administration on Skin Wound Regeneration. PATHOPHYSIOLOGY 2021; 28:355-372. [PMID: 35366280 PMCID: PMC8830469 DOI: 10.3390/pathophysiology28030024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 08/10/2021] [Accepted: 08/10/2021] [Indexed: 12/14/2022] Open
Abstract
Wound healing is an important medical problem. We evaluated the efficacy of locally administered mesenchymal stem cells (MSCs) isolated from human umbilical cords on the dynamics of skin wound healing. The study was conducted on the backs of Wistar rats, where two square wounds were created by removing all layers of the skin. Four groups were studied in two series of experiments: (1) a Control_NaCl group (the wounds were injected with 0.9% NaCl solution) and a Control_0 group (intact wounds on the opposite side of the same rat's back); (2) an MSC group (injected MSCs, local effect) and a Control_sc group (intact wounds on the opposite side of the back, remote MSC effect). The area and temperature of the wounds and the microcirculation of the wound edges were measured. Histological and morphometric studies were performed on days 3 and 7 after the wounds were created. The results showed that the injection trauma (Control_NaCl) slowed the regeneration process. In both MSC groups (unlike in either control group), we observed no increase in the area of the wounds; in addition, we observed inhibition of the inflammatory process and improved wound regeneration on days 1-3 in the remote group and days 1-5 in the local (injected) group. The MSC and Control_sc groups demonstrated improved microcirculation and suppression of leukocyte infiltration on day 3. On day 7, all the studied parameters of the wounds of the Control_0 group were the same as those of the wounds that received cell therapy, although in contrast to the results of the Control_ NaCl group, fibroblast proliferation was greater in the MSC and Control_sc groups. The dynamics of the size of the wounds were comparable for both local and remote application of MSCs. Thus, even a one-time application of MSCs was effective during the first 3-5 days after injury due to anti-inflammatory processes, which improved the regeneration process. Remote application of MSC, as opposed to direct injection, is advisable, especially in the case of multiple wounds, since the results were indistinguishable between the groups and injection trauma was shown to slow healing.

Abstract
Repair of large bone defects represents a major challenge for orthopedic surgeons. The newly formed microvessels inside grafts play a crucial role in successful bone tissue engineering. Previously, an active role for mesenchymal stem cell (MSC)-derived exosomes in blood vessel development and progression was suggested in the repair of multiple tissues. However, the reports on the application of MSC-derived exosomes in the repair of large bone defects are sparse. In this study, we encapsulated umbilical MSC-derived exosomes (uMSCEXOs) in hyaluronic acid hydrogel (HA-Gel) and combined them with customized nanohydroxyapatite/poly-ε-caprolactone (nHP) scaffolds to repair cranial defects in rats. Imaging and histological evaluation indicated that the uMSCEXOs/Gel/nHP composites markedly enhanced bone regeneration in vivo, and the uMSCEXOs might play a key role in this process. Moreover, the in vitro results demonstrated that uMSCEXOs promoted the proliferation, migration, and angiogenic differentiation of endothelial progenitor cells (EPCs) but did not significantly affect the osteogenic differentiation of BMSCs. Importantly, mechanistic studies revealed that exosomal miR-21 was the potential intercellular messenger that promoted angiogenesis by upregulating the NOTCH1/DLL4 pathway. In conclusion, our findings exhibit a promising exosome-based strategy in repairing large bone defects through enhanced angiogenesis, which potentially regulated by the miR-21/NOTCH1/DLL4 signaling axis.

Abstract
AIM To construct a competent corneal lamellar substitute in order to alleviate the shortage of human corneal donor. METHODS Rabbit mesenchymal stem cells (MSCs) were isolated from bone marrow and identified by flow cytometric, osteogenic and adipogenic induction. Xenogenic decellularized corneal matrix (XDCM) was generated from dog corneas. MSCs were seeded and cultured on XDCM to construct the tissue-engineered cornea. Post-transplantation biocompatibility of engineered corneal graft were tested by animal experiment. Rabbits were divided into two groups then underwent lamellar keratoplasty (LK) with different corneal grafts: 1) XDCM group (n=5): XDCM; 2) XDCM-MSCs groups (n=4): tissue-engineered cornea made up with XDCM and MSCs. The ocular surface recovery procedure was observed while corneal transparency, neovascularization and epithelium defection were measured and compared. In vivo on focal exam was performed 3mo postoperatively. RESULTS Rabbit MSCs were isolated and identified. Flow cytometry demonstrated isolated cells were CD90 positive and CD34, CD45 negative. Osteogenic and adipogenic induction verified their multipotent abilities. MSC-XDCM grafts were constructed and observed. In vivo transplantation showed the neovascularization in XDCM-MSC group was much less than that in XDCM group postoperatively. Post-transplant 3-month confocal test showed less nerve regeneration and bigger cell-absent area in XDCM-MSC group. CONCLUSION This study present a novel corneal tissue-engineered graft that could reduce post-operatively neovascularization and remain transparency, meanwhile shows that co-transplantation of MSCs may help increase corneal transplantation successful rate and enlarge the source range of corneal substitute to overcome cornea donor shortage.

Abstract
Purpose An assessment of the effectiveness of progenitor mesenchymal stem cell as injections and as part of a polymer hydrogel for the wounds treatment. Materials and Methods Fixed-size wounds (average area of 135.8 mm2) were modeled on the back of white Wistar rats, aged 9 months. Mesenchymal stem cells (MSC) isolated from a human umbilical cord were injected into the wounds once on the modeling day (SC group). In other animals, MSC were periodically applied externally as one of the components in the polymer hydrogel (Polymer_sc group). The systemic effect of the cells was assessed via the analysis of intact contralateral wounds located on the opposite side of the same animal’s back (groups Control_sc and Control_Psc, respectively). The reference intact wounds belonged to the Control_0 group. The wound area was studied in dynamics. Descriptive microscopy was supplemented by an assessment of the collagen fibers’ maturity, the epidermal layers, and the number of fibroblasts and leukocytes in different parts of the wounds. Results Both the local and systemic application of MSC led to an improvement in wound regeneration. During the acute inflammatory phase (up to 3 days), the method and place of application did not affect the dynamics of wound healing. The use of Polymer_sc ultimately demonstrated the best effectiveness. The anti-inflammatory effect of MSC was confirmed by a decrease in leukocyte infiltration in the wound centers (Polymer_sc and SC groups) and edges (all groups, with the greatest extent in the Polymer_sc group). The proliferative phase that expresses itself via accelerated growth in fibroblast number and collagen production was affected in the Control_Psc group and mostly in the Polymer_sc group. Conclusion The applications of MSC in various ways improve and accelerate wound healing even in old animals. The best performance was achieved in the Polymer_sc group.

Abstract
Inflammation is part of a complex biological response to injury that mediates a rapid mobilization of cells and triggers the restoration of tissue homeostasis. The systemic diseases of the connective tissues, repetitive strain injuries, neuropathy, and vascular impairment lead to the development of a chronic inflammatory state. In such cases, a forced intervention is required to trigger tissue regeneration. Mesenchymal stromal cells (MSCs) have been considered a perspective tool for regenerative medicine because of their ability to change the expression and secretory profile under the influence of signals from the microenvironment to perform a regulatory function at the site of tissue damage. In this study, MSCs were isolated from the human umbilical cord (UCMSCs). The ability of UCMSCs to regulate chronic inflammation was investigated in a randomized placebo-controlled pilot study to assess the efficacy and safety of UCMSC therapy in patients with nonhealing wounds. A total of 108 patients with chronic wounds of different etiologies were randomly divided into two groups according to the criteria of inclusion and exclusion. The group (n = 59) that was treated with a single local subcutaneous infusion of UCMSCs around the wound periphery showed a pronounced growth of granulation tissue, improved blood microcirculation, and reduction in wound size compared to the placebo group (n = 49). No prominent adverse events were detected in patients from the UCMSC group during the 1-year follow-up period. This research has demonstrated that locally delivered allogeneic UCMSCs can contribute to chronic wound repair and provide an additional support toward new therapeutic strategies. Registration certificate №FS2006/341 was issued by the Federal Service for Surveillance in Healthcare.

Abstract
We compared the effects of placental mesenchymal stromal cells and neural progenitor cells derived from induced human pluripotent cells after their intravenous administration to rats in 24 h after transitory occlusion of the middle cerebral artery. The therapeutic effects were evaluated by the dynamics of animal survival, body weight, neurological deficit, and the volume of infarction focus in 7, 14, 30, and 60 days after surgery. Intravenous injection of neural progenitor cells produced a therapeutic effect on the course of experimental ischemic stroke by increasing animal survival in the most acute period and accelerating compensation of neurological deficit and body weight recovery. Neural progenitor cells were more effective than mesenchymal stromal cells from human placenta. The effectiveness of intravenous transplantation of neural progenitor cells in the model of occlusion of the middle cerebral artery is shown by us for the first time, although the therapeutic effect of their direct transplantation into the brain has already been described.

Abstract
Endothelial dysfunction is a principle feature of vascular-related disease. Endothelial cells have been acquired for the purposes of the restoration of damaged tissue in therapeutic angiogenesis. However, their use is limited by expansion capacity and the small amount of cells that are obtained. Human amniotic fluid mesenchymal stem cells (hAF-MSCs) are considered an important source for vascular tissue engineering. In this study, hAF-MSCs were characterized and then induced in order to differentiate into the endothelial-like cells. Human amniotic fluid cells (hAFCs) were obtained from amniocentesis at the second trimester of gestation. The cells were characterized as mesenchymal stem cells by flow cytometry. The results showed that the cells were positive for mesenchymal stem cell markers CD44, CD73, CD90 and HLA-ABC, and negative for CD31, Amniotic fluid stem cells marker: CD117, anti-human fibroblasts, HLA-DR and hematopoietic differentiation markers CD34 and CD45. The hAF-MSCs were differentiated into endothelial cells under the induction of vascular endothelial growth factor (VEGF) and analyzed for the expression of the endothelial-specific markers and function. The expression of the endothelial-specific markers was determined by reverse transcriptase-quantitative PCR (RT-qPCR), while immunofluorescent analysis demonstrated that the induced hAF-MSCs expressed von Willebrand factor (vWF), vascular endothelial growth factor receptor 2 (VEGFR2), CD31 and endothelial nitric oxide synthase (eNOS). The network formation assay showed that the induced hAF-MSCs formed partial networks. All results indicated that hAF-MSCs have the potential to be differentiated into endothelial-like cells, while human amniotic fluid might be a suitable source of MSCs for vascularized tissue engineering.

Abstract
Several reports have been published on the isolation, culture, and identification of mesenchymal stem cells (MSCs) from different anatomical regions of the umbilical cord (UC). UC is suitable for standardizing methods of MSC isolation because it is a uniform source with high MSC numbers. Although the UC is considered a medical waste after childbirth, ethical issues for its use must be considered. An increased demand for MSCs in regenerative medicine has made scientists prioritize the development of MSC isolation methods. Several research groups are attempting to provide a large number of high-quality MSCs. In this study, we present a modulated explant/enzyme method (MEEM) to isolate the maximum number of MSCs from the entire UC. This method was established for the isolation of MSCs from different anatomical regions of the UC altogether. We could retrieve 6 to 10 million MSCs during 8 to 10 days of primary culture. After three passages, we could obtain 8–10 × 108 cells in 28–30 days. MSCs isolated by this method express CD73, CD90, CD105, and CD44, but they do not express hematopoietic markers CD34 and CD45 or the endothelial marker CD31. The genes SOX2, OCT4, and NANOG are expressed in isolated MSCs. The capacity of these MSCs to differentiate into adipocytes and osteocytes highlights their application in regenerative medicine. This method is simple, reproducible, and cost efficient. Moreover, this method is suitable for the production of a large number of high-quality MSCs from an UC in less than a month, to be used for cell therapy in an 80-kg person.

Abstract
The scope of this review is to revise recent advances of the cell-based therapies of liver diseases with an emphasis on cell donor's and patient's age. Regenerative medicine with cell-based technologies as its integral part is focused on the structural and functional restoration of tissues impaired by sickness or aging. Unlike drug-based medicine directed primarily at alleviation of symptoms, regenerative medicine offers a more holistic approach to disease and senescence management aimed to achieve restoration of homeostasis. Hepatocyte transplantation and organ engineering are very probable forthcoming options of liver disease treatment in people of different ages and vigorous research and technological innovations in this area are in progress. Accordingly, availability of sufficient amounts of functional human hepatocytes is crucial. Direct isolation of autologous hepatocytes from liver biopsy is problematic due to related discomfort and difficulties with further expansion of cells, particularly those derived from aging people. Allogeneic primary human hepatocytes meeting quality standards are also in short supply. Alternatively, autologous hepatocytes can be produced by reprogramming of differentiated cells through the stage of induced pluripotent stem cells. In addition, fibroblasts and mesenchymal stromal cells can be directly induced to undergo advanced stage hepatogenic differentiation. Reprogramming of cells derived from elderly people is accompanied by the reversal of age-associated changes at the cellular level manifesting itself by telomere elongation and the U-turn of DNA methylation. Cell reprogramming can provide high quality rejuvenated hepatocytes for cell therapy and liver tissue engineering. Further technological advancements and establishment of national and global registries of induced pluripotent stem cell lines homozygous for HLA haplotypes can allow industry-style production of livers for immunosuppression-free transplantation.

Abstract
INTRODUCTION We have identified some critical aspects concerning umbilical cord tissue mesenchymal stem cells: the lack of standards for cell isolation, expansion and cryopreservation, the lack of unanimous opinions upon their multilineage differentiation potential and the existence of very few results related to the functional characterization of the cells isolated from cryopreserved umbilical cord tissue. Umbilical cord tissue cryopreservation appears to be the optimal solution for umbilical cord tissue mesenchymal stem cells storage for future clinical use. Umbilical cord tissue cryopreservation allows mesenchymal stem cells isolation before expected use, according with the specific clinical applications, by different customized isolation and expansion protocols agreed by cell therapy institutions. METHODS Using an optimized protocol for umbilical cord tissue cryopreservation in autologous cord blood plasma, isolation explant method and growth media supplemented with FBS or human serum, we performed comparative studies with respect to the characteristics of mesenchymal stem cells (MSC) isolated from different compartments of the same umbilical cord tissue such as Wharton's jelly, vein, arteries, before cryopreservation (pre freeze) and after cryopreservation (post thaw). RESULTS Expression of histochemical and immunohistochemical markers as well as electron microscopy observations revealed similar adipogenic, chondrogenic and osteogenic differentiation capacity for cells isolated from pre freeze and corresponding post thaw tissue fragments of Wharton's jelly, vein or arteries of the same umbilical cord tissue, regardless growth media used for cells isolation and expansion. DISCUSSION Our efficient umbilical cord tissue cryopreservation protocol is reliable for clinical applicability of mesenchymal stem cells that could next be isolated and expanded in compliance with future accepted standards.

Abstract
Umbilical cord mesenchymal stem cells (UC-MSCs) show properties similar to bone marrow mesenchymal stem cells (BM-MSCs), although controversial data exist regarding their osteogenic potential. We prepared clinical-grade UC-MSCs from Wharton's Jelly and we investigated if UC-MSCs could be used as substitutes for BM-MSCs in muscoloskeletal regeneration as a more readily available and functional source of MSCs. UC-MSCs were loaded onto scaffolds and implanted subcutaneously (ectopically) and in critical-sized calvarial defects (orthotopically) in mice. For live cell-tracking experiments, UC-MSCs were first transduced with the luciferase gene. Angiogenic properties of UC-MSCs were tested using the mouse metatarsal angiogenesis assay. Cell secretomes were screened for the presence of various cytokines using an array assay. Analysis of implanted scaffolds showed that UC-MSCs, contrary to BM-MSCs, remained detectable in the implants for 3 weeks at most and did not induce bone formation in an ectopic location. Instead, they induced a significant increase of blood vessel ingrowth. In agreement with these observations, UC-MSC-conditioned medium presented a distinct and stronger proinflammatory/chemotactic cytokine profile than BM-MSCs and a significantly enhanced angiogenic activity. When UC-MSCs were orthotopically transplanted in a calvarial defect, they promoted increased bone formation as well as BM-MSCs. However, at variance with BM-MSCs, the new bone was deposited through the activity of stimulated host cells, highlighting the importance of the microenvironment on determining cell commitment and response. Therefore, we propose, as therapy for bone lesions, the use of allogeneic UC-MSCs by not depositing bone matrix directly, but acting through the activation of endogenous repair mechanisms.

Abstract
Mesenchymal stem or stromal cells (MSCs) have a high potential for cell-based therapies as well as for tissue engineering applications. Since Friedenstein first isolated stem or precursor cells from the human bone marrow (BM) stroma that were capable of osteogenesis, BM is currently the most common source for MSCs. However, BM presents several disadvantages, namely low frequency of MSCs, high donor-dependent variations in quality, and painful invasive intervention. Thus, tremendous research efforts have been observed during recent years to find alternative sources for MSCs.In this context, the human umbilical cord (UC) has gained more and more attention. Since the UC is discarded after birth, the cells are easily accessible without ethical concerns. This postnatal organ was found to be rich in primitive stromal cells showing typical characteristics of bone-marrow MSCs (BMSCs), e.g., they grow as plastic-adherent cells with a fibroblastic morphology, express a set of typical surface markers, and can be directly differentiated at least along mesodermal lineages. Compared to BM, the UC tissue bears a higher frequency of stromal cells with a higher in vitro expansion potential. Furthermore, immune-privileged and immune-modulatory properties are reported for UC-derived cells, which open highly interesting perspectives for clinical applications.

Abstract
Murine MSCs are a readily available source of adult stem cells enabling extensive in vitro study of this cell population. MSCs have been described as multipotent, and have been proven capable of differentiation into several connective tissue types. Furthermore some studies have suggested an ability to differentiate into non-connective tissue cell types such as the cardiomyocyte. The aim of this study was to differentiate murine MSCs toward cardiac lineage with the commonly used method of culture with 5' Azacytidine. Critically, baseline analysis of gene expression of passage four MSCs demonstrated expression of key cardiac markers including cardiac troponin T and I, and the ryanodine receptor. Furthermore, expression analysis of these genes changed with time in culture and passage number. However, there was no significant alteration when cells were subjected to a differentiation protocol. This study therefore highlights the importance of analyzing baseline cells extensively, and indicates the limitations in extrapolating data for comparison between species. Furthermore this data brings into question the efficacy of cardiac differentiation using MSCs.

Abstract
Mesenchymal stem or stromal cells (MSC) have proven to offer great promise for cell-based therapies and tissue engineering applications, as these cells are capable of extensive self-renewal and display a multilineage differentiation potential. Furthermore, MSC were shown to exhibit immunomodulatory properties and display supportive functions through parakrine effects. Besides bone marrow (BM), still today the most common source of MSC, these cells were found to be present in a variety of postnatal and extraembryonic tissues and organs as well as in a large variety of fetal tissues. Over the last decade, the human umbilical cord and human amnion have been found to be a rich and valuable source of MSC that is bio-equivalent to BM-MSC. Since these tissues are discarded after birth, the cells are easily accessible without ethical concerns.

Abstract
Mesenchymal stem cells (MSCs) have potential for use in regenerative therapeutics, since they are capable of multi-lineage differentiation. In this study, primary canine MSCs (cMSCs) were isolated from bone marrow aspirates and characterised using marker expression and morphology. cMSCs expressed CD44 and STRO-1, but not CD34 or CD45. Morphologically, cMSCs were similar to previously described MSCs and were capable of chondrocyte differentiation towards articular type cartilage, characterised by increased collagen type II vs. collagen type I expression and expression of Sox-9. cMSCs demonstrated no significant alterations in marker profiles and failed to differentiate into cardiomyocytes in response to a cardiac differentiation protocol or when co-cultured with canine cardiac stem cells. The study indicated that cMSCs can be derived readily from bone marrow and are capable of differentiation into articular cartilage, but appear to have limited ability to differentiate into cardiomyocytes using current protocols.

Abstract
Up to 2.8 × 10(7) fibroblast-like cells displaying an abundant presence of mesenchymal stem cell (MSC) markers CD73, CD90, CD105 and a low level of HLA-I expression can be isolated from one whole human umbilical cord (UC) using a simple and highly reproducible explant culture approach. Cells derived from whole UC, similar to cells collected from separate compartments of UC, display a distinct chondrogenic and adipogenic potential. Therefore they are potential candidates for cartilage and adipose tissue engineering. Cell differentiation along the osteogenic pathway is, however, less efficient, even after the addition of 1.25-dihydroxyvitamin D3, a potent osteoinductive substance. Isolated cells are highly proliferative, tolerate cryopreservation with an average survival rate of about 75% and after thawing can be propagated further, at least over 20 population doublings before their proliferative activity begins to decline. More importantly, they synthesize numerous trophic factors including neurotrophins and factors which facilitate angiogenesis and hematopoiesis. In conclusion, cells isolated from whole UC satisfies all requirements essential for the generation of stem cell banks containing permanently available cell material for applications in the field of regenerative medicine. Nevertheless, further studies are needed to improve and adjust the methods which are already employed for adult MSC expansion and differentiation to specific properties and requirements of the primitive stem cells collected from UC. So, our data verify that the choice of individual parameters for cell propagation, such as duration of cell expansion and cell seeding density, has a substantial impact on the quality of UC-derived cell populations.

Abstract
BACKGROUND AIMS Mesenchymal stromal cells (MSC) have recently been identified as a therapeutic option in several clinical conditions. Whereas bone marrow (BM) is considered the main source of MSC (BM-MSC), the invasive technique required for collection and the decline in allogeneic donations call for alternative sources. Human umbilical cord (UC) represents an easily available source of MSC (UC-MSC). METHODS Sections of full-term UC were transferred to cell culture flasks and cultured in 5% human platelet lysate (PL)-enriched medium. Neither enzymatic digestion nor blood vessel removal was performed. After 2 weeks, the adherent cells were harvested (P1), replated at low density and expanded for two consecutive rounds (P2 and P3). RESULTS We isolated and expanded MSC from 9/9 UC. UC-MSC expanded with a mean fold increase (FI) of 42 735 ± 16 195 from P1 to P3 in a mean of 29 ± 2 days. By processing the entire cord unit, we theoretically could have reached a median of 9.5 × 10(10) cells (ranging from 1.0 × 10(10) to 29.0 × 10(10)). UC-MSC expressed standard surface markers; they contained more colony-forming unit (CFU)-fibroblast (F) and seemed less committed towards osteogenic, chondrogenic and adipogenic lineages than BM-MSC. They showed immunosuppressive properties both in vitro and in an in vivo chronic Graft versus Host disease (cGvHD) mouse model. Both array-Comparative Genomic Hybridization (CGH) analysis and karyotyping revealed no chromosome alterations at the end of the expansion. Animal studies revealed no tumorigenicity in vivo. CONCLUSIONS UC constitute a convenient and very rich source of MSC for the production of third-party 'clinical doses' of cells under good manufacturing practice (GMP) conditions.

Abstract
Along with angiogenesis and gene therapy, stem cell transplantation is one of the newest treatment modalities proposed to improve the outcome of patients with heart failure or infarction. In this context, much interest has stemmed from experimental studies showing that cardiac transfer of unfractionated or partially purified bone marrow cells, or stem cells and progenitor cells derived from the bone marrow or peripheral blood, can enhance functional recovery after an acute myocardial infarction. On the basis of these data, stem cells and progenitor cells derived from the bone marrow have been proposed for use in the repair of cardiac tissue after acute myocardial infarction in patients. However, the relatively low abundance, small tissue volume, difficult accessibility and disease-related malfunction of bone marrow-derived stem cells make their clinical usefulness difficult in some situations. Recently it has been shown that adipose tissue contains a population of adult multipotent mesenchymal stem cells and endothelial progenitor cells that, in cell culture conditions, have extensive proliferative capacity and are able to differentiate into several lineages, including endothelial cells, smooth muscle cells and cardiomyocytes. The similarities between stem cells extracted from the bone marrow and the adipose tissue suggest the potential for the adipose tissue to act as an alternative, and perhaps preferable, cell source for repairing damaged tissues, such as the ischemic or infarcted heart. In this review we discuss molecular and functional characterization, preclinical results and currently ongoing clinical trials using adipose-derived stem cells in cardiovascular repair.

Abstract
Mesenchymal stem cells (MSCs) represent a promising source of progenitor cells having the potential to repair and to regenerate diseased or damaged skeletal tissues. Bone marrow (BM) has been the first source reported to contain MSCs. However, BM-derived cells are not always acceptable, due to the highly invasive drawing and the decline in MSC number and differentiative capability with increasing age. Human umbilical cord blood (UCB), obtainable by donation with a noninvasive method, has been introduced as an alternative source of MSCs. Here human UCB-derived MSCs isolation and morpho-functional characterization are reported. Human UCB-derived mononuclear cells, obtained by negative immunoselection, exhibited either an osteoclast-like or a mesenchymal-like phenotype. However, we were able to obtain homogeneous populations of MSCs that displayed a fibroblast-like morphology, expressed mesenchym-related antigens and showed differentiative capacities along osteoblastic and early chondroblastic lineages. Furthermore, this study is one among a few papers investigating human UCB-derived MSC growth and differentiation on three-dimensional scaffolds focusing on their potential applications in regenerative medicine and tissue engineering. UCB-derived MSCs were proved to grow on biodegradable microfiber meshes; additionally, they were able to differentiate toward mature osteoblasts when cultured inside human plasma clots, suggesting their potential application in orthopedic surgery.

Abstract
Glandular stem cells (GSCs) can be obtained from exocrine glands such as pancreas or salivary glands using well-established cell culturing methods. The resulting cell populations are characterized by a high proliferative capacity and an unusually high plasticity. Cells from pancreas have been demonstrated to differentiate into a multitude of cell types and even into oocyte-like cells. It has been found that the preparation method for GSCs can be applied to many vertebrates, including fishes and birds. Since the cells are excellently cryopreservable, this finding has been utilized to establish a new stem cell bank for preserving living cells of rare and wild animals. Apart from these advances, this mini-review also points out that GSCs from pancreas must not be confused with beta-cell progenitors but constitute a distinct cell type.
