Localization of the low-affinity nerve growth factor receptor p75 in human limbal epithelial cells
Biological effects of nerve growth factor (NGF) are mediated through receptors known as nerve growth factor receptors (NGFR), which include p75 and TrkA. This study was initiated after identifying NGFR as an up-regulated gene in the limbus by cDNA microarray analysis and we postulate that its expression may be indicative of a stem/progenitor cell phenotype. Immunohistochemistry was performed on...
متن کاملExpression of trk in MAH cells lacking the p75 low-affinity nerve growth factor receptor is sufficient to permit nerve growth factor-induced differentiation to postmitotic neurons.
We have transfected MAH cells, an immortalized sympathoadrenal progenitor cell line, with a plasmid encoding the 140-kDa Trk protein, a nerve growth factor (NGF) receptor with protein-tyrosine kinase activity. NGF promotes neurite outgrowth and proliferation from such cells, indicating that Trk is sufficient to mediate such responses in the absence of significant levels of the endogenous 75-kDa...
متن کاملThe low-affinity p75 nerve growth factor (NGF) receptor mediates NGF-induced tyrosine phosphorylation.
Protein tyrosine phosphorylation is a potential mechanism for initial signaling in PC12 cells during differentiation in response to nerve growth factor (NGF). NGF-induced tyrosine phosphorylation has been found to be initiated by the trk protooncogene, which participates in the formation of high-affinity NGF binding sites. In contrast to transfection of wild-type low-affinity p75 NGF receptors,...
متن کاملNerve growth factor in human semen: Effect of nerve growth factor on the normozoospermic men during cryopreservation process
Objective(s):Althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. Adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm DNA fragmentation and infertility. The post-thaw survival of sperm...
متن کاملAge-Related Yield of Adipose-Derived Stem Cells Bearing the Low-Affinity Nerve Growth Factor Receptor
Adipose-derived stem cells (ADSCs) are a heterogeneous cell population that may be enriched by positive selection with antibodies against the low-affinity nerve growth factor receptor (LNGFR or CD271), yielding a selective cell universe with higher proliferation and differentiation potential. This paper addresses the need for determining the quantity of ADSCs positive for the CD271 receptor and...
