Functional recovery of neurons in the spinal cord after physical injury is essentially abortive in clinical cases. As neurotrophins had been reported to be responsible, at least partially, for the lesion-induced recovery of spinal cord, it is not surprising that they have become the focus of numerous studies. Studies on endogenous neurotrophins, especially(More)
BACKGROUND AIMS The characteristics, such as morphologic and phenotypic characteristics and neural transdifferentiation ability, of mesenchymal stromal cells (MSC) derived from different origins have yet to be reported for cases isolated from the same individual. METHODS The proliferation capacity, secretion ability of neurotrophins (NT) and neural(More)
An animal model of transected spinal cord injury (SCI) was used to test the hypothesis that cografted human umbilical mesenchymal stem cells-derived neurospheres (HUMSC-NSs) and BDNF can promote morphologic and functional recoveries of injured spinal cord. In vitro, HUMSC-NSs terminally differentiated into higher percentages of cells expressing neuronal(More)
Transdifferentiated and untransdifferentiated mesenchymal stem cells (MSCs) have shown therapeutic benefits in central nervous system (CNS) injury. However, it is unclear which would be more appropriate for transplantation. To address this question, we transplanted untransdifferentiated human umbilical mesenchymal stem cells (HUMSCs) and transdifferentiated(More)
Endothelial progenitor cells (EPCs) are responsible for postnatal vasculogenesis in physiological and pathological neovascularization. Adipose tissue (AT) is an abundant source of mesenchymal stem cells (MSCs), which have multipotent differentiation ability. We successfully derived EPCs from AT, which maintained a strong proliferative capacity and(More)
The aim of this study was to compare the neural differentiation potential and the expression of neurotrophic factors (NTFs) in differentiated adipose-derived stem cells (ADSCs) using three established induction protocols, serum free (Protocol 1), chemical reagents (Protocol 2), and spontaneous (Protocol 3) protocols. Protocol 1 produced the highest(More)
Although human amnion derived mesenchymal stem cells (AMSC) are a promising source of stem cells, their therapeutic potential for traumatic brain injury (TBI) has not been widely investigated. In this study, we evaluated the therapeutic potential of AMSC using a rat TBI model. AMSC were isolated from human amniotic membrane and characterized by flow(More)
BACKGROUND AIMS This study aimed to observe nine factors expressed in rat ischemic brain after transplantation of bone marrow stromal cells (BMSC) and/or endothelial progenitor cells (EPC). These factors were vascular endothelial growth factor (VEGF), stromal cell-derived factor-1 (SDF-1), basic fibroblast growth factor (bFGF), insulin-like growth factor(More)
Human Wharton's jelly-derived mesenchymal stromal cells (hWJ-MSCs) are capable of differentiating into neural and astroglia-like cell types. However, a reliable means of inducing the selective differentiation of hWJ-MSCs into oligodendrocyte progenitor cells (OPCs) in vitro has not yet been established. In this study, the OPC-like differentiation of(More)
Controversies exist concerning the need for mesenchymal stromal cells (MSCs) to be transdifferentiated prior to their transplantation. In the present study, we compared the results of grafting into the rat contused spinal cord undifferentiated, adipose tissue-derived stromal cells (uADSCs) versus ADSCs induced by two different protocols to form(More)
