Embryonic stem cells can proliferate indefinitely and are capable of differentiating into derivatives of all three embryonic germ layers in vitro, including the neural lineage. The main objective of this study is to test the effects of neural stem cell conditioned medium on the neural differentiation of mouse embryonic stem cells. When cultured in neural(More)
A gene's transcriptional output is the combined product of two inputs: diffusible factors in the cellular milieu acting in trans, and chromatin state acting in cis. Here, we describe a strategy for dissecting the relative contribution of cis versus trans mechanisms to gene regulation. Referred to as trans complementation, it entails fusing two disparate(More)
In this study, we explored the competence of adipose-derived stem cells to differentiate into Schwann cells in vitro. Rat adipose-derived stem cells were sequentially treated with various factors beta-mercaptoethanol, all-trans-retinoic acid, followed by a mixture of forskolin, basic fibroblast growth factor, platelet-derived growth factor and heregulin. We(More)
Neural stem cells are multipotent and self-renewing cells with important potential application in cell replacement therapy in brain damage. Many studies have shown that nestin-positive cells represent neural stem and progenitor cells in the central neural system. Here, we derived neural stem cells from the subventricular zone of a newborn(More)
OBJECTIVE To reveal the expression and possible roles of aquaporin 9 (AQP9) in rat brain, after severe traumatic brain injury (TBI). METHODS Brain water content (BWC), tetrazolium chloride staining, Evans blue staining, immunohistochemistry (IHC), immunofluorescence (IF), western blot, and real-time polymerase chain reaction were used. RESULTS The BWC(More)
Techniques for small molecule screening are widely used in biological mechanism study and drug discovery. Here, we reported a novel adipocyte differentiation assay for small molecule selection, based on human mesenchymal stem cells (hMSCs) transduced with fluorescence reporter gene driven by adipogenic specific promoter--adipocyte Protein 2 (aP2; also(More)
BACKGROUND Laparoscopic resections for submucosal tumors (SMTs) of the stomach have been developed rapidly over the past decade. Several types of laparoscopic methods for gastric SMTs have been created. We assessed the short-term outcomes of two commonly used types of laparoscopic local resection (LLR) for gastric SMTs and reported our findings. METHODS(More)
The bond quality is critical to stress transfer between fiber reinforced polymer, FRP, and concrete structures. The efficacy of externally bonded FRP systems could be reduced significantly due to defects at the FRP-concrete interface. Infrared thermography is an effective tool for locating such defects in a non-contact fashion. Current study examined the(More)
OBJECTIVE To investigate the impact of experimental brain injury on the noradrenergic (NA) neurons in the spinal cord, in order to explore possible mechanism of the changes in NA neuron expression. METHODS Seventy healthy Wistar rats were randomly divided into two groups: normal group (n=10), brain injury (BI) group (n=60). The animals in BI group were(More)
