BACKGROUND The aim of this study was to isolate mesenchymal stem cells (MSCs) from amniotic fluid obtained by second-trimester amniocentesis. METHODS A novel two-stage culture protocol for culturing MSCs was developed. Flow cytometry, RT-PCR and immunocytochemistry were used to analyse the phenotypic characteristics of the cultured MSCs.

Recent evidence has shown that amniotic fluid may be a novel source of fetal stem cells for therapeutic transplantation. We previously developed a two-stage culture protocol to isolate a population of amniotic fluid-derived mesenchymal stem cells (AFMSCs) from second-trimester amniocentesis. AFMSCs maintain the capacity to differentiate into multiple(More)
Bone marrow and umbilical cord blood are reported to be the main sources of mesenchymal stem cells (MSCs), which have been proposed for many clinical applications. This study evaluated and quantitated the differentiation potential of bone marrow-derived MSCs (bmMSCs) and cord blood-derived MSCs (cbMSCs) by in vitro induction. Results indicated that cbMSCs(More)
The amniotic membrane has been clinically applied as a therapeutic material in wound covering and corneal surface reconstruction. Recently, mesenchymal stem cells (MSCs) have been isolated from the placenta, specifically from the amniotic membrane. However, the localization of MSCs in the amniotic membrane has not been determined. In this study, term(More)
We used cytokine protein array to analyze the expression of cytokines from human cord blood-derived mesenchymal stem cells (CB-MSCs). Several cytokines, interleukins (IL), and growth factors, including ENA-78, GM-CSF, GRO, IL-1beta, IL-6, IL-8, MCP-1, OSM, VEGF, FGF-4, FGF-7, FGF-9, GCP-2, IGFBP-1, IGFBP-2, IGFBP-3, IGFBP-4, IP-10, LIF, MIF, MIP-3alpha,(More)
Using high-density oligonucleotide microarrays and functional network analyses, we examined whether MSCs derived from four different origins exhibited unique gene expression profiles individually and then compared the gene expression profiles of all MSCs with those of fetal organs. Our results indicated that within each group of MSCs from the same origin,(More)
Chitinous materials have been studied in wound healing and artificial skin substitutes for many years. Nitric oxide (NO) has been shown to contribute to cytotoxicity in cell proliferation during inflammation of wound healing. In this study, we examined the effect of chitin and its derivatives on NO production by activated RAW 264.7 macrophages. Chitin and(More)
Cell transplantation via direct intramyocardial injection is a promising therapy for patients with myocardial infarction; however, retention of the transplanted cells at the injection sites remains a central issue following injection of dissociated cells. Using a thermoresponsive hydrogel system with a multiwell structure, we successfully developed an(More)
BACKGROUND AIMS A clinically applicable tolerance induction regimen that removes the requirement for lifelong immunosuppression would benefit recipients of vascularized composite allotransplantation (VCA). We characterized the immunomodulatory properties of syngeneic (derived from the recipient strain) adipocyte-derived stem cells (ADSCs) and investigated(More)
Human embryonic stem cells (hESCs), due to their self-renewal capacity and pluripotency, are an important source of cells for regenerative medicine. The immediate obstacles that need to be addressed are the poor cell survival rate of hESCs and their cell quality after cryopreservation. In this study, we used the Cell Alive System (CAS) which combines a(More)
