Abstract
Cryopreservation of human corneal stroma-derived mesenchymal stromal cells (hCS-MSCs) with dimethylsulfoxide (DMSO) as a cryoprotective agent (CPA) has not been previously compared to that with glycerol under standard conditions. The hCS-MSCs were hereby cryopreserved with both compounds using a freezing rate of 1 °C/minute. The CPAs were tested by different concentrations in complete Minimum Essential Medium (MEM) approved for good manufacturing practice, and a medium frequently used in cell laboratory culturing-Dulbecco's modified eagle serum. The hCS-MSCs were isolated from cadaveric human corneas obtained from the Norwegian Eye Bank, and immunophenotypically characterized by flow cytometry before and after cryopreservation. The survival rate, the cellular adhesion, proliferation and cell surface coverage after cryopreservation of hCS-MSCs has been studied. The hCS-MSCs were immunofluorescent stained and examined for their morphology microscopically. The results showed that cryopreservation of hCS-MSCs in MEM with 10% glycerol gives a higher proliferation rate compared to other cryopreserving media tested. Based on the results, hCS-MSCs can safely be cryopreserved using glycerol instead of the traditional use of DMSO.

Abstract
Human umbilical cord mesenchymal stem cells (hUC-MSCs) have considerable potential in cell therapy. Cryopreservation represents the gold standard in cell storage, but its effect on hUC-MSCs is still not well understood. The aim of this study was to investigate the effect of one year of cryopreservation and thawing on the biological characteristics of hUC-MSCs from the same donors. Fresh hUC-MSCs were cryopreserved in commercial freezing medium (serum-free CellBanker 2) at passage 2. After one year of cryopreservation, the hUC-MSCs were thawed and subcultured to passage 4. The comparison was performed in terms of followings: cell count, viability, morphology, proliferation capacity, differentiation potential and chromosomal stability. The total cell count and viability of hUC-MSCs before and after one year of cryopreservation were 1 × 107 and 96.34% and 0.943 × 107 and 93.81%, respectively. Cryopreserved and fresh hUC-MSCs displayed a similar cell doubling times, expressed the markers CD73, CD90, CD105 and were negative for the markers CD34, CD45, and HLA-DR. Karyotypes were found to be normal after one year of cryopreservation. The trilineage differentiation properties were maintained after cryopreservation. However, when compared to freshly isolated hUC-MSCs from the same donor, cryopreserved hUC-MSCs exhibited decreased expression of osteogenesis- and chondrogenesis-related genes including Runx2, Sox9, and Col1a1, and increased expression of adipogenesis-related genes. These results demonstrated that cryopreservation did not affect cell morphology, surface marker expression, cell viability, proliferative capacity, or chromosomal stability. However, the osteogenic and chondrogenic differentiation capacities of cryopreserved hUC-MSCs were slightly reduced compared with those of fresh cells from the same donor.

Abstract
Cryoprotective agents (CPAs) are essential for the cryopreservation of cells. Thus far, dimethyl sulfoxide (DMSO) has been widely used as a CPA; however, DMSO is known to be toxic to cells. The damaged cells by the toxicity can present abnormal conditions, and should not be used for regenerative medical products because the cells/products are implanted directly into human bodies. With the aim of searching for an alternative CPA to DMSO, this work presents a computational screening of CPA candidate compounds using quantum chemistry and molecular dynamics (MD) simulations. Forty compounds were evaluated in regard to the solvation free energy and partition coefficient by quantum chemistry simulation and the root mean square deviation (RMSD) of a phospholipid bilayer which composes a cell membrane by MD simulation. The solvation free energy, partition coefficient, and RMSD were defined as indicators of osmoregulatory ability, affinity with a cell membrane, and ability to spread a cell membrane, respectively. The quantum chemistry simulation elucidated that the six compounds of trimethylglycine, formamide, urea, thiourea, diethylene glycol, and dulcitol were better than DMSO in either or both of the physical properties considered. This finding is based on the inherent physical property and is thus case-independent. Further characterization with the MD simulation suggested that formamide, thiourea, and urea should be the first candidates to investigate, although the result was valid only in the simulated condition. This work serves as the first step of multi-faceted computational evaluation of multiple compounds in the search for an effective CPA compound after DMSO.

A clinical perspective on adipose-derived cell therapy for enhancing microvascular health and function: Implications and applications for reconstructive surgery. Microcirculation 2020; 28:e12672.

Abstract
Restoration of form and function requires apposition of tissues in the form of flaps to reconstitute local perfusion. Successful reconstruction relies on flap survival and its integration with the recipient bed. The flap's precariously perfused hypoxic areas undergo adaptive microvascular changes both internally and in connection with the recipient bed. A cell-mediated, coordinated response to hypoxia drives these adaptive processes, restoring a tissue's normoxic homeostasis via de novo vasculogenesis, sprouting angiogenesis, and stabilizing arterialization. As cells exert prolonged and coordinated effects on site, their use as biological agents merit translational consideration of sourcing angio-competent cells and delivering them to territories enduring microcirculatory acclimatization. Angio-competent cells abound in adipose tissue: a reliable, accessible, and expendable source of adipose-derived cells (ADC). When subject to enzymatic digestion and centrifugation, adipose tissue separates its various ADC: A subset of buoyant oil-dense adipocytes (the tissue's parenchymal component) accumulates on a supra-natant layer, whereas the mesenchymal component remains in the infra-natant sediment, containing the tissue's stromal vascular fraction (SVF), where angio-component cells abound. The SVF can be further manipulated, selected, or culture expanded into more specific stromal subsets (herein defined as adipose stromal cells, ASC). While promising clinical applications for ADC await clinical proof and regulatory authorization, basic science investigation is needed to elucidate the specific ADC mechanisms that influence microvascular growth, remodeling, and function following flap surgery. The objective of this article is to share the clinical perspectives of reconstructive plastic surgeons regarding the use of ADC-based therapies to help with flap tissue integration, revascularization, and wound healing. Specifically, the focus will be on considering the potential for ADC as therapeutic agents and how their clinical application motivates basic science opportunities.

Abstract
Currently, fat transplantation occurs immediately after harvesting procedures. Because low rates of fat graft take are well reported in the literature, many patients require multiple surgical procedures for fat graft harvest. These subsequent procedures lead to increased cost, donor-site morbidity, and patient discomfort in the long term. The ability to preserve our patients' own adipose aspirate would allow us to counteract these shortcomings and ultimately improve the clinical outcome after fat grafting. Unfortunately, there is no optimal and practical adipose tissue cryopreservation protocol for use by the plastic surgeon at the present time. Because of this dilemma, the senior author (L.L.Q.P.) has investigated this concept in an effort to create a protocol that is both technically sound and clinically achievable to allow for the long-term preservation of adipose tissue. In this article, the authors aim to outline this effort, review current clinical applications that have been reported in the literature, and detail exciting future perspectives in the use of preserved lipoaspirates for repeated fat grafting procedures or in the form of cell-based therapy engineered for reconstructive endeavors for their patients.

Abstract
Freezing is recognized as the most effective method of maintaining a stable supply of
various cell types for long-term storage. However, cells might be damaged by environmental
changes during the freezing process. There are various factors that influence the function
of cells cultured after cryopreservation and thawing. These factors include
cryopreservation solutions, biomaterials, freezing methods, and the freezing and
preservation temperatures. There is also a risk of infection with mycoplasma in liquid
nitrogen phase. Therefore, it is necessary to consider more useful and safe methods for
freezing and storing various cells. In this study, we investigated the effects of
temperature during long-term storage (8 years at −80 °C and in liquid nitrogen phase) on
the quality of various cells (human hepatocellular carcinoma cells, bovine carotid artery
normal endothelial cells, mouse fibroblast cells 3T3, and mouse embryo fibroblast cells
STO). We examined the cell viability of cryopreserved human hepatocellular carcinoma cells
at −80 °C using culture medium containing 10% DMSO, Cell Banker 1, and Cell Banker 2 as
cryopreservation solutions. Among these solutions, Cell Banker 1 showed the highest
efficiency. The viability of human hepatocellular carcinoma and bovine carotid artery
normal endothelial cells in the Cell Banker 1 stored at −80 °C was over 90%, which was the
same as that in liquid nitrogen phase. The cells stored at −80 °C had a morphology similar
to that of the cells stored at liquid nitrogen phase. The proliferation of cells stored at
−80 °C and in liquid nitrogen phase was not significantly different. Furthermore, none of
the cells were infected with mycoplasma. There was no marked difference in the albumin
secretion between the human hepatocellular carcinoma cells stored at −80 °C and those in
liquid nitrogen phase. The short tandem repeats of the human hepatocellular carcinoma
cells stored at −80 °C were identical to those stored in liquid nitrogen phase. In this
report, various cells stored long-term at −80 °C were able to be used effectively after
long-term storage. These findings can be applied to drug discovery, cell medicine, and
cell therapy.

Abstract
The application of stem cells for cell therapy has been extensively studied in recent years. Among the various types of stem cells, human adipose tissue-derived stem cells (ASCs) can be obtained in large quantities with relatively few passages, and they possess a stable quality. ASCs can differentiate into a number of cell types, such as adipose cells and ectodermal cells. We therefore focused on the in vitro microenvironment required for such differentiation and attempted to induce the differentiation of human stem cells into microtissues using a microelectromechanical system. We first evaluated the adipogenic differentiation of human ASC spheroids in a three-dimensional (3D) culture. We then created the in vitro microenvironment using a 3D combinatorial TASCL device and attempted to induce the adipogenic differentiation of human ASCs. The differentiation of human ASC spheroids cultured in maintenance medium and those cultured in adipocyte differentiation medium was evaluated via Oil red O staining using lipid droplets based on the quantity of accumulated triglycerides. The differentiation was confirmed in both media, but the human ASCs in the 3D cultures contained higher amounts of triglycerides than those in the 2D cultures. In the short culture period, greater adipogenic differentiation was observed in the 3D cultures than in the 2D cultures. The 3D culture using the TASCL device with adipogenic differentiation medium promoted greater differentiation of human ASCs into adipogenic lineages than either a 2D culture or a culture using a maintenance medium. In summary, the TASCL device created a hospitable in vitro microenvironment and may therefore be a useful tool for the induction of differentiation in 3D culture. The resultant human ASC spheroids were "adipose-like microtissues" that formed spherical aggregation perfectly and are expected to be applicable in regenerative medicine as well as cell transplantation.

Abstract
Adipose-derived mesenchymal stem cells (ASCs) have the potential to differentiate into cells of mesodermal origin, such as osteoblasts, adipocytes, myocytes, and chondrocytes, and cryopreservation is currently performed as a routine method for preserving ASCs to safely acquire large numbers of cells. For clinical application of ASCs, serum-free, xeno-free cryopreservation solutions should be used. This study determined the viability and adipo-osteogenic potential of cryopreserved ASCs using four cryopreservation solutions: 10% DMSO, Cell Banker 2 (serum free), Stem Cell Banker (=Cell Banker 3: serum free, xeno free), and TC protector (serum free, xeno free). The viability of the cryopreserved ASCs was over 80% with all cryopreservation solutions. No difference in the adipo-osteogenic potential was found between the cells that did or did not undergo cryopreservation in these cryopreservation solutions. These data suggest that Cell Banker 3 and TC protector are comparable with 10% DMSO and Cell Banker 2 for ASCs, and cryopreserved as well as noncryopreserved ASCs could be applied for regenerative medicine.

Abstract
The capability of multipotent mesenchymal stem cells to maintain cell viability, phenotype and differentiation ability upon thawing is critical if they are to be banked and used for future therapeutic purposes. In the present study, we examined the effect of 9-10 months of cryostorage on the morphology, immunophenotype, colony-forming unit (CFU) and differentiation capacity of fresh and cryopreserved human adipose-derived stromal/stem cells (ASCs) from the same donors. Cryopreservation did not reduce the CFU frequency and the expression levels of CD29, CD73, CD90 and CD105 remained unchanged with the exception of CD34 and CD45; however, the differentiation capacity of cryopreserved ASCs relative to fresh cells was significantly reduced. While our findings suggest that future studies are warranted to improve cryopreservation methods and agents, cryopreserved ASCs retain sufficient features to ensure their practical utility for both research and clinical applications.

Abstract
Aim. The effects of cryopreservation on adipose tissue-derived mesenchymal stem cells are not clearly documented, as there is a growing body of evidence about the importance of adipose-derived mesenchymal stem cells for regenerative therapies. The aim of this study was to analyze human adipose tissue-derived mesenchymal stem cells phenotypic expression (CD34, CD45, CD73, CD90, CD105, and CD49d), colony forming unit ability, viability, and differentiation potential before and after cryopreservation. Materials and Methods. 12 samples of the adipose tissue were collected from a healthy donor using the liposuction technique. The cell isolation was performed by enzymatic digestion and then the cells were cultured up to passage 2. Before and after cryopreservation the immunophenotype, cellular viability analysis by flow cytometer, colony forming units ability, differentiation potential into adipocytes and osteoblasts as demonstrated by Oil Red O and Alizarin Red staining, respectively. Results. The immunophenotypic markers expression was largely preserved, and their multipotency was maintained. However, after cryopreservation, the cells decreased α4-integrin expression (CD49d), cell viability, and number of colony forming units. Conclusions. These findings suggest that ADMSC transplanted after cryopreservation might compromise the retention of transplanted cells in the host tissue. Therefore, further studies are warranted to standardize protocols related to cryopreservation to attain full benefits of stem cell therapy.

Abstract
Mesenchymal stem cells (MSCs) have the potential to differentiate into cells of mesodermal origin such as osteoblasts, adipocytes, myocytes, and chondrocytes. They possess an immunosuppressive effect, which makes them a viable cell population for the cell-based therapy of treatment-resistant immune diseases. Adipose-derived mesenchymal stem cells (ASCs) have been demonstrated to have the ability to acquire the properties of subcutaneous adipose tissue particularly easily, and cryopreservation is currently performed as a routine method for preserving ASCs to safely acquire large numbers of cells. However, many studies have reported that cellular activity after freezing and thawing may be affected by the solutions used for cryopreservation. Dimethyl sulfoxide (DMSO) is commonly used as a cryopreservation medium as it diffuses into the cell through the plasma membrane and protects the cells from the damage caused by freezing. As substitutes for DMSO or animal-derived serum, cell banker series, polyvinylpyrrolidone (PVP), sericin and maltose, and methyl cellulose (MC) have been investigated for their clinical applications. It is critical to develop a reliable cell cryopreservation protocol for regenerative medicine using MSCs.

Abstract
Adipose-derived mesenchymal stromal cells are promising as a regenerative therapy tool for defective tissues in mesenchymal lineage, including fat, bone, cartilage, and blood vessels. In potential future clinical applications, adipose-derived stem cell cryopreservation is an essential fundamental technology. The aim of this study is to define an adequate protocol for the cryopreservation of adipose-derived mesenchymal stromal cells, by comparing various protocols so as to determine the effects of cryopreservation on viability and chondrogenic differentiation potential of adipose-derived stem cells upon freeze-thawing of AT-MSCs colonies cryopreserved with standard and modified protocols, using flow cytometry and confocal microscopy. The study concludes that adipose-derived mesenchymal stromal cells could be long-term cryopreserved without any loss of their proliferative or differentiation potential.

Abstract
Stem cell transplantation has been expected to have various applications for regenerative medicine. However, in order to detect and trace the transplanted stem cells in the body, non-invasive and widely clinically available cell imaging technologies are required. In this paper, we focused on magnetic resonance (MR) imaging technology, and investigated whether the trimethylamino dextran-coated magnetic iron oxide nanoparticle -03 (TMADM-03), which was newly developed by our group, could be used for labeling adipose tissue-derived stem cells (ASCs) as a contrast agent. No cytotoxicity was observed in ASCs transduced with less than 100 µg-Fe/mL of TMADM-03 after a one hour transduction time. The transduction efficiency of TMADM-03 into ASCs was about four-fold more efficient than that of the alkali-treated dextran-coated magnetic iron oxide nanoparticle (ATDM), which is a major component of commercially available contrast agents such as ferucarbotran (Resovist), and the level of labeling was maintained for at least two weeks. In addition, the differentiation ability of ASCs labeled with TMADM-03 and their ability to produce cytokines such as hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF) and prostaglandin E2 (PGE2), were confirmed to be maintained. The ASCs labeled with TMADM-03 were transplanted into the left kidney capsule of a mouse. The labeled ASCs could be imaged with good contrast using a 1T MR imaging system. These data suggest that TMADM-03 can therefore be utilized as a contrast agent for the MR imaging of stem cells.

Abstract
Cinco cavalos adultos foram submetidos à coleta de medula óssea do esterno e de tecido adiposo da região glútea. As amostras foram processadas para obtenção da fração mononuclear da medula óssea e fração vascular estromal do tecido adiposo, o número de células obtidas e a viabilidade celular foram determinados. Em seguida, realizou-se o congelamento das amostras em solução contendo 20% de soro fetal bovino e 10% de dimetilsulfóxido. Depois de um mês, realizou-se o descongelamento das amostras e a viabilidade celular foi novamente mensurada. Os resultados revelaram que as técnicas utilizadas tanto para coleta de medula óssea quanto de tecido adiposo em equinos são simples, rápidas e seguras. As metodologias adotadas para o processamento das amostras foram eficientes, obtendo-se aproximadamente 95% de viabilidade celular. Após o descongelamento, a viabilidade média das amostras de células mononucleares da medula óssea foi de 86% e da fração vascular estromal do tecido adiposo de 64%. Frente à importância da terapia celular na clínica médica de equinos, concluiu-se que é necessária a realização de mais estudos, visando padronizar uma técnica de criopreservação que mantenha a integridade das células da fração mononuclear da medula óssea e da fração vascular estromal do tecido adiposo de equinos.

Abstract
Adipose tissue-derived stem/progenitor cells (ASCs) have attracted attention as a cell source that replaces marrow stromal cells (MSCs); ASCs may thus have applications in both regenerative medicine and cell transplantation. These medical treatments, however, require a high-quality supply of human ASCs. Therefore, the cryopreservation methods have been improved by changing a component of a cryopreservation medium. Sericin, a protein hydrolysate (with an average molecular weight of 30 kDa) is very rich in serine. The viability and the adipogenic/osteogenic potential of human ASCs were tested after freezing in a cryopreservation medium containing sericin. After thawing, the viability of the human ASCs frozen in the cryopreservation medium was found to be more than 95%. The proliferation rate of human ASCs frozen in CELLBANKER 2, and DMEM/Ham's F-12 medium (serum free) + 10% DMSO, 0.1 mol/L maltose, and 1% sericin was higher than that of the cells frozen in the maintenance medium + 10% DMSO. The adipogenic/osteogenic differentiation capabilities of frozen human ASCs were examined by Oil Red O staining/Von Kossa's method. The human ASCs were frozen using CELLBANKER 2, and DMEM/Ham's F-12 medium (serum free) + 10% DMSO, 0.1 mol/L maltose, and 1% sericin were positive. In conclusion, the cryopreservation medium containing sericin is therefore considered to have a beneficial effect on freezing human ASCs. This serum-free cryopreservation medium should be widely used in regenerative medicine, cell transplantation, and biological research.

Abstract
Induced pluripotent stem (iPS) cells have attracted attention as a promising cell source for medical treatment that could replace marrow stromal cells (MSCs) and adipose tissue-derived stem cells (ASCs). These pluripotent cells can be induced in vitro and in vivo to differentiate into various tissues and organs. The cells will be useful for regenerative medicine, cell therapy, and drug screening. Vitrification is used, as well as a rapid-freeze method, for colony-forming iPS cells. However, the method requires a high degree of technical skill. We herein report a more convenient method for freezing iPS cells in suspension. We examined the proliferation potency of cryopreserved mouse iPS cells using culture medium, 10% DMSO, 10% glycerol, 5% DMSO, 5% glycerol, 5% DMSO + 5% glycerol, cell-freezing medium-DMSO, cell-freezing medium-glycerol, Cell Banker 1, Cell Banker 1+, Cell Banker 2, and Cell Banker 3 as cryopreservation solutions. Among them, Cell Banker 3 showed the highest efficacy in terms of the proliferation of mouse iPS cells. The mouse iPS cells cryopreserved in Cell Banker 3 at -80°C for 12 months maintained a high proliferation rate and an undifferentiated status. The formation of teratomas was also examined. In conclusion, Cell Banker 3 allows for freezing of iPS cells in suspension.

Abstract
BACKGROUND The aim of the present study was to investigate whether adipose-derived stem cells could contribute to skeletal muscle-healing. METHODS Adipose-derived stem cells of male rats were cultured and injected into the soleus muscles of female rats. Two and four weeks after injections, muscles were tested for tetanic force (50 Hz). Histological analysis was performed to evaluate muscle collagen deposition and the number of centronucleated muscle fibers. In order to track donor cells, chimerism was detected with use of real-time polymerase chain reaction targeting the male sex-determining region Y (SRY) gene. RESULTS Two weeks after cell injection, tetanus strength and the number of centronucleated regenerating myofibers, as well as the number of centronucleated regenerating myofibers, were higher in the treated group than they were in the control group (mean and standard error of the mean, 79.2 ± 5.0% versus 58.3 ± 8.1%, respectively [p < 0.05]; and 145 ± 36 versus 273 ± 18 per 10³ myofibers, respectively [p < 0.05]). However, there were no significant differences at four weeks. Treatment did not decrease collagen deposition. Male gene was not detected in female host tissue at two and four weeks after engraftment by polymerase chain reaction analysis. CONCLUSIONS Adipose-derived stem-cell therapy increased muscle repair and force at two weeks, but not four weeks, after injection, suggesting that adipose-derived stem-cell administration may accelerate muscle repair; however, the rapid disappearance of injected cells suggests a paracrine mechanism of action.

Abstract
As the average age of the population grows, the incidence of osteoporosis and skeletal diseases continues to rise. Current treatment options for skeletal repair include immobilization, rigid fixation, alloplastic materials, and bone grafts, all which have significant limitations, especially in the elderly. Adipose-derived stromal cells (ASCs) represent a readily available abundant supply of mesenchymal stem cells, which demonstrate the ability to undergo osteogenesis in vitro and in vivo, making ASCs a promising source of skeletal progenitor cells. Current protocols allow for the harvest of over one million cells from only 15 ml of lipoaspirate. Despite the clinical use of ASCs to treat systemic inflammatory diseases, no large human clinical trials exist using ASCs for skeletal tissue engineering. The aim of this review is to define ASCs, to describe the isolation procedure of ASCs, to review the basic biology of their osteogenic differentiation, discuss cell types and scaffolds available for bone tissue engineering, and finally, to explore imaging of ASCs and their potential future role in human skeletal tissue engineering efforts.

Abstract
The spread of HIV continues unabated in the most vulnerable populations of the world. HIV prevention methods, such as a vaginal microbicide, a mucosal vaccine, pre-exposure prophylaxis or a vaccine, are urgently needed in the fight against new infections. We must make a commitment to supporting innovative research and product design, so that one or more of these products provide a halt to the spread of HIV. Above all, these products should be proven to be safe and not negatively disturb the local immune system in a way that facilitates or enhances heterosexual transmission of HIV. HIV specific and non specific cellular and humoral local vaginal immunity must be assessed in clinical trials when testing prevention products for safety or efficacy. A proven, well-documented and standardized sampling strategy will provide high quality data to be able to assess both safety and local immune responses. In this paper, we will discuss methods for vaginal immunology sampling in the context of clinical trials.

Abstract
If the rapidly progressing field of stem cell research reaches its full potential, successful treatments and enhanced understanding of many diseases are the likely results. However, the full potential of stem cell science will only be reached if all possible avenues can be explored and on a worldwide scale. Until 2009, the US had a highly restrictive policy on obtaining cells from human embryos and fetal tissue, a policy that pushed research toward the use of adult-derived cells. Currently, US policy is still in flux, and retrospective analysis does show the US lagging behind the rest of the world in the proportional increase in embryonic/fetal stem cell research. The majority of US studies being on either a limited number of cell lines, or on cells derived elsewhere (or funded by other sources than Federal) rather than on freshly isolated embryonic or fetal material. Neural, mesenchymal, and the mixed stem cell mononuclear fraction are the most commonly investigated types, which can generally be classified as adult-derived stem cells, although roughly half of the neural stem cells are fetal derived. Other types, such as embryonic and fat-derived stem cells, are increasing in their prominence, suggesting that new types of stem cells are still being pursued. Sixty percent of the reported stem cell studies involved transplantation, of which over three quarters were allogeneic transplants. A high proportion of the cardiovascular systems articles were on allogeneic transplants in a number of different species, including several autologous studies. A number of pharmaceutical grade stem cell products have also recently been tested and reported on. Stem cell research shows considerable promise for the treatment of a number of disorders, some of which have entered clinical trials; over the next few years it will be interesting to see how these treatments progress in the clinic.

Abstract
Human adipose-derived stromal cells (hASCs) represent a multipotent stromal cell type with a proven capacity to undergo osteogenic differentiation. Many hurdles exist, however, between current knowledge of hASC osteogenesis and their potential future use in skeletal tissue regeneration. The impact of frozen storage on hASC osteogenic differentiation, for example, has not been studied in detail. To examine the effects of frozen storage, hASCs were harvested from lipoaspirate and either maintained in standard culture conditions or frozen for 2 weeks under standard conditions (90% fetal bovine serum, 10% dimethyl sulfoxide). Next, in vitro parameters of cell morphology (surface electron microscopy [EM]), cell viability and growth (trypan blue; bromodeoxyuridine incorporation), osteogenic differentiation (alkaline phosphatase, alizarin red, and quantitative real-time (RT)-polymerase chain reaction), and adipogenic differentiation (Oil red O staining and quantitative RT-polymerase chain reaction) were performed. Finally, in vivo bone formation was assessed using a critical-sized cranial defect in athymic mice, utilizing a hydroxyapatite (HA)-poly(lactic-co-glycolic acid) scaffold for ASC delivery. Healing was assessed by serial microcomputed tomography scans and histology. Freshly derived ASCs differed significantly from freeze-thaw ASCs in all markers examined. Surface EM showed distinct differences in cellular morphology. Proliferation, and osteogenic and adipogenic differentiation were all significantly hampered by the freeze-thaw process in vitro (*P < 0.01). In vivo, near complete healing was observed among calvarial defects engrafted with fresh hASCs. This was in comparison to groups engrafted with freeze-thaw hASCs that showed little healing (*P < 0.01). Finally, recombinant insulin-like growth factor 1 or recombinant bone morphogenetic protein 4 was observed to increase or rescue in vitro osteogenic differentiation among frozen hASCs (*P < 0.01). The freezing of ASCs for storage significantly impacts their biology, both in vitro and in vivo. The ability of ASCs to successfully undergo osteogenic differentiation after freeze-thaw is substantively muted, both in vitro and in vivo. The use of recombinant proteins, however, may be used to mitigate the deleterious effects of the freeze-thaw process.

Abstract
Despite advances in wound closure techniques and devices, there is still a critical need for new methods of enhancing the healing process to achieve optimal outcomes. Recently, stem cell therapy has emerged as a new approach to accelerate wound healing. Adipose-derived stem cells (ASCs) hold great promise for wound healing, because they are multipotential stem cells capable of differentiation into various cell lineages and secretion of angiogenic growth factors. The aim of this study was to evaluate the benefit of ASCs on wound healing and then investigate the probable mechanisms. ASCs characterized by flow cytometry were successfully isolated and cultured. An excisional wound healing model in rat was used to determine the effects of locally administered ASCs. The gross and histological results showed that ASCs significantly accelerated wound closure in normal and diabetic rat, including increased epithelialization and granulation tissue deposition. Furthermore, we applied GFP-labeled ASCs on wounds to determine whether ASCs could differentiate along multiple lineages of tissue regeneration in the specific microenvironment. Immunofluorescent analysis indicated that GFP-expressing ASCs were costained with pan-cytokeratin and CD31, respectively, indicating spontaneous site-specific differentiation into epithelial and endothelial lineages. These data suggest that ASCs not only contribute to cutaneous regeneration, but also participate in new vessels formation. Moreover, ASCs were found to secret angiogenic cytokines in vitro and in vivo, including VEGF, HGF, and FGF2, which increase neovascularization and enhance wound healing in injured tissues. In conclusion, our results demonstrate that ASC therapy could accelerate wound healing through differentiation and vasculogenesis and might represent a novel therapeutic approach in cutaneous wounds.

Abstract
β-Cell replacement therapy via islet transplantation is an effective treatment for diabetes mellitus, but its widespread use is severely limited by the shortage of donor organs. Because pancreatic stem/progenitor cells are abundantly available in the pancreas of these patients and in donor organs, the cells could become a useful target for β-cell replacement therapy. We previously established a mouse pancreatic stem cell line without genetic manipulation. In this study, we used the techniques to identify and isolate human pancreatic stem/progenitor cells. The cells from a duct-rich population were cultured in 23 kinds of culture media, based on media for mouse pancreatic stem cells or for human embryonic stem cells. The cells in serum-free media formed "cobblestone" morphologies, similar to a mouse pancreatic stem cell line. On the other hand, the cells in serum-containing medium and the medium for human embryonic stem cells formed "fibroblast-like" morphologies. The cells divided actively until day 30, and the population doubling level (PDL) was 6-10. However, the cells stopped dividing after 30 days in any culture conditions. During the cultures, the nucleus/cytoplasm (N/C) ratio decreased, suggesting that the cells entered senescence. Exendin-4 treatment and transduction of PDX-1 and NeuroD proteins by protein transduction technology into the cells induced insulin and pancreas-related gene expression. Although the duplications of these cells were limited, this approach could provide a potential new source of insulin-producing cells for transplantation.

Abstract
Cryoprotective agents (CPAs) such as dimethyl sulfoxide (DMSO), glycerol, ethylene glycol, and propylene glycol have been used for the cryopreservation of cells and tissues. DMSO is the most effective CPA but shows high cytotoxicity and can effect differentiation. ∈-Poly-l-lysine (PLL) derivatives show higher cryopreservation efficiency than the conventional CPAs. Culture medium solutions with 7.5 w/w% of PLL whose amino groups of more than 50 mol% were converted to carboxyl groups by succinic anhydride showed higher postthaw survival efficiency of L929 cells than those of current CPAs without the addition of any proteins. In addition, rat mesenchymal stem cells were cryopreserved more effectively than with DMSO and fully retained the potential for proliferation and differentiation. Furthermore, many kinds of cells could be cryopreserved with PLL having the appropriate ratio of COOH groups, regardless of the cell types, including adhesive and floating cells, human- and mouse-derived cells, primary cells, and established cell lines. The properties might be associated with the antifreeze protein properties. These results indicate that these polymeric extracellular CPAs may replace current CPAs and the high viability after thawing and nonnecessity of serum ensure that these CPAs may be used in various preservation fields.

Abstract
The technologies for adipose tissue harvesting, processing, and transplantation have substantially evolved in the past two decades. Clinically driven advancements have paralleled a significant improvement in the understanding of cellular, molecular, and immunobiological events surrounding cell and tissue transplantation. These new mechanistic insights could be of assistance to better understand the mechanisms underlying some of the observed clinical improvements. In addition to plastic and reconstructive surgical applications, adipose tissue has become central to an increasing number of translational efforts involving adipose tissue-derived progenitor cells. The growing interest in this area of research has resulted in the exploration of many novel research and clinical applications that utilize adipose tissue grafting and/or progenitor/stem cell- derived cell products obtained from this tissue source. Progenitor, endothelial, and mesenchymal stem cells derived from adipose tissue could therefore not only be central to plastic and reconstructive surgery applications, but also become the focus of an array of therapeutic solutions for many disease conditions, such as those affecting bone, cartilage, muscle, liver, kidney, cardiac, neural, and the pancreas, expanding the possible indications and translational potential of tissue, cell-based, and regenerative medicine strategies.

Abstract
PURPOSE The previous in vitro study showed that trehalose, when used as a cryoprotective agent (CPA) in an optimal concentration, can provide adequate protection of adipose aspirates during cryopreservation. OBJECTIVE The authors evaluated the efficacy of trehalose in its optimal concentration for cryopreservation of human fat grafts in a well-established animal model. METHODS In this study (n = 20 in each group), adipose aspirates were harvested and processed from a female patient; the protocol for freezing and thawing of fat grafts was the same as the in vitro study. In the control group, 0.5 mL of fresh fat grafts was injected into the posterior scalp of a nude mouse. In the cryopreservation group 1, a combination of dimethyl sulfoxide (in 0.5M) and trehalose (in 0.2M) was injected as a CPA. In the cryopreservation group 2, only the optimal concentration of trehalose (in 0.35M) was administered as a CPA. In both cryopreservation groups, 0.5 mL of cryopreserved fat grafts was thawed and injected into the animal in the same manner as the control group. All animals in each group were observed for gross appearance of maintained fat grafts over their posterior scalps for up to eight weeks. The final volume and weight of maintained fat grafts and their histology were evaluated at the end of the study. RESULTS Group 2, compared with group 1, respectively, had equivalently maintained volume (38.2 +/- 10.1% versus 46.1 +/- 14.4%, ns) and weight (34.1 +/- 12.1% versus 38.9 +/- 14.7%, ns). However, the results from both cryopreservation groups were still inferior to those from the control group (both P < .05). Histologically, the basic structure of adipose tissue was maintained in all three groups. CONCLUSION Trehalose, serving as a CPA in its optimal concentration, appears to provide adequate protection of human fat grafts during cryopreservation in vivo. Such protection is similar to that provided by the combination of dimethyl sulfoxide and trehalose as a CPA. Because of its safety and effectiveness, trehalose can possibly be administered to patients for long-term preservation of their fat grafts.

Abstract
The effect of adipose tissue-derived stem cells (ASCs) in combination with heparin transplantation on acute liver failure mice with carbon tetrachloride (CCl4) injection was investigated. CCl4 is a well-known hepatotoxin and induces hepatic necrosis. Heparin did not affect the viability of ASCs for at least 24 h. The injection of heparin into the caudal tail vein decreased slightly the activities of the alanine aminotransferase (ALT), asparate aminotransferase (AST), and lactate dehydrogenase (LDH) in plasma. In the transplantation of ASCs (1 × 106 cells) group, there was a trend toward decreased activities of all markers. However, four out of six mice died of the lung infarction. In the transplantation of ASCs in combination with heparin group, there was also a trend toward decreased activities of all markers. In addition, all mice survived for at least the duration of the study period. In conclusion, the transplantation of ASCs in combination with heparin was thus found to effectively treat acute liver failure.

Abstract
Sendai virus (SeV) vectors have potential clinical applications because they can efficiently introduce foreign genes without toxicity into various organs. A recent study reported the green fluorescent protein (GFP) gene transfer to adipose tissue-derived stem cells (ASCs) with SeV vectors results in more efficient expression of GFP than AdV and identified the preservation of the multilineage potential of ASCs transfected with SeV vectors. This study assessed the gene transfer efficiency to floating ASCs with SeV vectors. Although a slight cytotoxicity was observed, the efficiency of gene transfer to cells in the floating state was much higher at all times and all concentrations at MOIs of 2, 10, and 20 than in the adhesion state. Moreover, ASCs transfected with SeV vectors in floating state have the same potential for their differentiation into specific tissues, such as adipocytes and osteocytes, as untransfected ASCs. These data suggest that SeV transfection to ASCs in the floating state could therefore be useful for gene transfer technology.

Abstract
Efficient gene transfer into stem cells is essential for the basic research and for therapeutic applications in gene-modified regenerative medicine. Adenovirus (AdV) vectors, one of the most commonly used types of vectors, can mediate high, albeit transient, levels of expression of the transgene in pancreatic stem/progenitor cells. However, high multiplicity of infection (MOI) with AdV vectors can result in cellular toxicity. Therefore, AdV vectors have been of limited usefulness in clinical applications. In this study, we investigated the in vitro gene transfer efficiency of Sendai virus (SeV) vectors, a paramyxovirus vector that can efficiently introduce foreign genes without toxicity into several cell types, including pancreatic stem cells. The dose-dependent GFP expression of pancreatic stem cells transfected with SeV vectors after 48 h of culture at 37°C was observed. The transfection of pancreatic stem cells with SeV vectors and AdV vectors results in equal expression of the transgene (GFP expression) in the cells after 48 h of culture at 37°C. Although the transfection of pancreatic stem cells with AdV vectors at high MOIs was cytotoxic, transfection with SeV vectors at high MOIs was rarely cytotoxic. In addition, pancreatic stem cells transfected with SeV maintained their differentiation ability. These data suggest that SeV could provide advantages with respect to safety issues in gene-modified regenerative medicine.

Abstract
Adipose tissue-derived stem cells (ASCs) have a self-renewing ability and can be induced to differentiate into various types of mesenchymal tissue. Because of their potential for clinical application, it has become desirable to label the cells for tracing transplanted cells and for in vivo imaging. Quantum dots (QDs) are novel inorganic probes that consist of CdSe/ZnS-core/shell semiconductor nanocrystals and have recently been explored as fluorescent probes for stem cell labeling. In this study, negatively charged QDs655 were applied for ASCs labeling, with the cationic liposome, Lipofectamine. The cytotoxicity of QDs655-Lipofectamine was assessed for ASCs. Although some cytotoxicity was observed in ASCs transfected with more than 2.0 nM of QDs655, none was observed with less than 0.8 nM. To evaluate the time dependency, the fluorescent intensity with QDs655 was observed until 24 h after transfection. The fluorescent intensity gradually increased until 2 h at the concentrations of 0.2 and 0.4 nM, while the intensity increased until 4 h at 0.8 nM. The ASCs were differentiated into both adipogenic and osteogenic cells with red fluorescence after transfection with QDs655, thus suggesting that the cells retain their potential for differentiation even after transfected with QDs655. These data suggest that QDs could be utilized for the labeling of ASCs.

Abstract
Somatic stem cells can be isolated from a variety of sources. Although some studies have suggested that somatic stem cells may represent a cell population that is very similar to embryonic stem (ES) cells, it remains unclear whether somatic stem cells retain the potential to differentiate into any cell type derived from the three germ layers. In this study, we investigated the transdifferentiation potential of somatic stem cells using adipose tissue-derived stem/progenitor cells (ASCs; mesodermal stem cells) and pancreatic stem cells (endodermal stem cells). Previous reports from other groups describe the protocol that has been used to differentiate ASCs or mesenchymal stem cells (MSCs) in bone marrow into insulin-producing cells. Induction 1: ASCs were cultured for 3 days in ultra-low attachment plates under serum-free conditions. Induction 2: ASCs were cultured for 24 h with L-DMEM, and reinduced with serum-free H-DMEM for another 10 h. Unlike previous reports, we did not get ASCs to express any pancreas-specific genes, including insulin-1 or insulin-2. Pancreatic stem cells were induced to differentiate into adipo/osteogenic by the following protocols. Induction protocol 1: ACSs were cultured for 7 days with medium containing indometacin, dexamethasone, hydrocortisone, and insulin for adipogenic differentiation. Induction protocol 2: The cells were cultured for 7 days with medium containing dexamethasone, ascorbate-2-phosphate, and β-glycerophosphate for osteogenic differentiation. Although these approaches have been widely used for adipo/osteogenic differentiation from MSCs, adipo/osteogenic differentiation from pancreatic stem cells was not observed. These data suggest that it is not easy for somatic stem cells to transdifferentiate into other germ cell types, at least, under these conditions.

Abstract
Over the past decade, cell therapy has emerged as a new approach to reversing myocardial ischemia. Several types of adult stem cells have been studied in both preclinical and clinical conditions for this purpose: bone marrow cells, circulating cells, and myoblasts. Nevertheless, the quest for the ideal “anti-ischemic” cell is still ongoing. Recently, the existence of a population of stem cells located in adipose tissue (adipose-derived stem cells) has been observed. These are able to differentiate into multiple cell lineages including cardiomyocytic differentiation. In this review we discuss the basic principles of adipose-derived stem cells (types and characteristics, harvesting, and expansion), the initial experimental studies, and the currently ongoing clinical trials.
