Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...

enrichment of cell suspension with germ cells prior to injection into recipient seminiferous tubules is of importance in spermatogonial stem cells (sscs) transplantation. knock-out serum replacement (ksr) has been reported to enhance the proliferation of murine sscs and human embryonic stem cells. the aim of the present study was to investigate the effect of ksr versus fetal bovine serum (fbs) ...

background: some antidepressant drugs can promote neuronal cell proliferation in vitro as well as hippocampal neurogenesis in human and animal models. furthermore, adipose tissue is an available source of adult stem cells with the ability to differentiate in to multiple lineages. therefore, human adipose-derived stem cells (hadscs) may be a suitable source for regenerative medical applications....

The p53 tumor suppressor protein plays a pivotal role in preventing uncontrolled cellular proliferation. By contrast, zinc deprivation enhances esophageal cell proliferation and the induction of esophageal tumors in rodents by N-nitrosomethylbenzylamine (NMBA). We investigated whether p53 deficiency rendered zinc-deficient (ZD) mice more susceptible to NMBA-induced esophageal/forestomach carcin...
