spinal cord injury (sci) is one of the devastating conditions leading to functional and neurological deficits following road traffic accidents. to date, there is no definite treatment for repairing damaged spinal cord tissue. in this regard, cell therapy opens a new window in front of scientists by using different cells such as mesenchymal stem cells, olfactory ensheathing cells, schwann cells,...

In Sandhoff disease (SD), the activity of the lysosomal hydrolytic enzyme, β-hexosaminidase (Hex), is lost due to a Hexb gene defect, which results in the abnormal accumulation of the substrate, GM2 ganglioside (GM2), in neuronal cells, causing neuronal loss, microglial activation, and astrogliosis. We established induced pluripotent stem cells from the cells of SD mice (SD-iPSCs). In the prese...

Mutations in WD40-repeat protein 62 (WDR62) are commonly associated with primary microcephaly and other developmental cortical malformations. We used human pluripotent stem cells (hPSC) to examine WDR62 function during human neural differentiation and model early stages of human corticogenesis. Neurospheres lacking WDR62 expression showed decreased expression of intermediate progenitor marker, ...

background: gastrointestinal stromal tumors (gists) constitute the majority of gastrointestinal mesenchymal tumors. they usually express a proto-oncogen protein called cd117 detected by immunohistochemistry. this study investigated the differentiation of gists as well as the risk of aggressive behaviors in gists from surgically-treated patients in university affiliated hospitals.   methods: the...

OBJECTIVE The effects on neural proliferation and differentiation of neural stem cells (NSC) of basic fibroblast growth factor-2 (bFGF), insulin growth factor-I (IGF-I), brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF) were assessed. Also, following combinations of various factors were investigated : bFGF+IGF-I, bFGF+BDNF, bFGF+NGF, IGF-I+BDNF, IGF-I+NGF, and BDNF+NGF. ...
