objective(s): to investigate the efficacy of interleukin 11 (il-11) towards the high dose methotrexate (hdmtx)-concurrent rat small intestinal mucositis and its impacts on the proliferation of the human t-lymphoblastic leukemia (cem) cell line. materials and methods:95 wistar rats were randomly divided into five groups, the normal control group (a), the methotrexate (mtx) control group (b), the...

background: human dental stem cells have high proliferative potential for self-renewal that is important to the regenerative capacity of the tissue. objective: the aim was to isolate human dental pulp stem cells (dpsc), periodontal ligament stem cells (pdlsc) and periapical follicle stem cells (pafsc) for their potential role in tissue regeneration. materials and methods: in this experimental s...

the effects of mobile phone exposure on humans, due to its potential health hazards, have become the focus of interest since many years ago. the effect of global system for mobile communications (gsm 900 mhz) on growth and proliferation rate of mesenchymal stem cells was assessed at the different distances and intensities of radiation. a subscriber identity module (sim) card was inserted to thi...

In order to improve the shoot proliferation rate of ‘Dwarf Cavendish’ banana shoot tip cultures, polyethylene glycol (PEG6000) was employed at concentrations of 2, 4, and 6% (w/v). The medium without PEG was considered as negative control. An increasing of shoot proliferation was achieved in MS medium containing 2% PEG. Furthermore, application of 2% PEG significantly increased the shoot dry we...

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....

objective(s): umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  the objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. materials and ...
