a common pathological process that occurred after brain injury is gliosis. gliosis involves the activation of glial cells to proliferate and become hypertrophic to occupy the injured brain areas. in order to form a defense system against the invasion of micro-organisms and cytotoxins into surrounding tissue, glial cells including astrocytes and microglia undergo reactive response to injury. neu...
one of the major complications in cancer chemotherapy is the development of resistance, and cisplatin, as one of the important medicines in treatment regimens of different cancers is not excluded. one of the most described cellular defense mechanisms involved in resistance is glutathione (gsh) and in this study, the effects of cisplatin on the total intracellular gsh level (gshi) in some sensit...
We have immortalized rat central nervous system (CNS) cells of primary cultures of rat optic nerve with murine leukemia virus psi-2,SV-40-6, which is defective in assembly and contains the SV-40 large T antigen and neomycin resistance genes, to produce a cell line that we named A7. After drug selection, greater than 90% of the growing cells expressed nuclear SV-40 large T cells and a fraction o...
The stereotyped distribution of identified neurons and glial cells in the leech nervous system is the product of stereotyped cell migrations and rearrangements during embryogenesis. To examine the dependence of long-distance cell migrations on positional cues provided by other tissues, embryos of Theromyzon rude were examined for the effects of selective ablation of various embryonic cell lines...
Neuroepithelial stem cells (NEPs), glial-restricted precursors (GRPs), and neuron-restricted precursors (NRPs) are present during early differentiation of the spinal cord and can be identified by cell surface markers. In this article, we describe the properties of GRP cells that have been immortalized using a regulatable v-myc retrovirus construct. Immortalized GRP cells can be maintained in an...
We have found glial fibrillary acidic protein (GFAP), the major component of astrocyte intermediate filaments, to be expressed in cell lines of the RT4 peripheral neurotumor family. The RT4 family is a "stem-cell-like" cell line, RT4-AC, that spontaneously undergoes differentiation in culture to three derivative cell types. This process, termed cell-type conversion, results in a segregation amo...
background: spermatogonial stem cells (sscs), a subset of undifferentiated type a spermatogonia, are the foundation of complex process of spermatogenesis and could be propagated in vitro culture conditions for long time for germ cell transplantation and fertility preservation. objective: the aim of this study was in vitro propagation of human spermatogonial stem cells (sscs) and improvement of ...
objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...
