We examined the hypothesis that activation of the apoptosis cascade occurs relatively early in diabetes mellitus affecting three distinct neuronal populations that are involved in regulating gut function: (i) dorsal root ganglion (DRG), (ii) vagus nodose ganglion and (iii) colon myenteric plexus. A validated streptozotocin-induced diabetic rat model and(More)
Tenascin-R (TN-R) is a neural specific protein and an important molecule involved in inhibition of axonal regeneration after spinal cord injury (SCI). Here we report on rabbit-derived TN-R polyclonal antibody, which acts as a TN-R antagonist with high titer and high specificity, promoted neurite outgrowth and sprouting of rat cortical neurons cultured on(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)
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)
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)
The underlying mechanism for electroacupuncture (EA) associated functional improvement in patients suffering from spinal cord injury (SCI) is largely unknown. Collateral sprouting is one plausible factor, where the cord microenvironment may contribute greatly. The present study evaluated the effects of EA on collateral sprouting from spared dorsal root(More)
An animal model for clip spinal cord injury (SCI) was used to determine whether Neurotrophin-3 (NT-3) genetically modified human umbilical mesenchymal stem cells (NT-3-HUMSCs) could promote the morphologic and functional recovery of injured spinal cords. Using the Basso, Beattie, and Bresnahan scores and a grid test, the rats in the HUMSC-treated and(More)
BACKGROUND Chronic psychological stress (CPS) is associated with increased intestinal epithelial permeability and visceral hyperalgesia. It is unknown whether corticosterone (CORT) plays a role in mediating alterations of epithelial permeability in response to CPS. METHODS Male rats were subjected to 1-h water avoidance (WA) stress or subcutaneous CORT(More)
OBJECTIVE To explore the relationship between Insulin-like growth factor-I (IGF-I) and acupuncture promoting the spinal cord plasticity, the changes of IGF- I expressing in spared dorsal root ganglia (DRG,L6) after operation and acupuncture were investigated. METHODS 25 adult cats were divided into 5 groups: normal control group; 7th day and 14th day(More)
