BACKGROUND Adipose tissue contains an abundant population of multipotent adipose-derived stem cells (ASCs) and has been an excellent source of mesenchymal stem cells for cell therapy and tissue engineering. To ensure successful cell therapies, consistency of stem cell performance across donors is critical. However, the effect of the donor's reproductive status on ASC proliferation rate and diff...

With age, the growth plate undergoes senescent changes that cause linear bone growth to slow and finally cease. Based on previous indirect evidence, we hypothesized that this senescent decline occurs because growth plate stem-like cells, located in the resting zone, have a finite proliferative capacity that is gradually depleted. Consistent with this hypothesis, we found that the proliferation ...

BACKGROUND Long term effects of different doses of ionizing radiation on human skeletal muscle myoblast proliferation, cytokine signalling and stress response capacity were studied in primary cell cultures. MATERIALS AND METHODS Human skeletal muscle myoblasts obtained from muscle biopsies were cultured and irradiated with a Darpac 2000 X-ray unit at doses of 4, 6 and 8 Gy. Acute effects of r...

Neural stem cells are undifferentiated cells that are located in limited areas of central nervous system. These cells have proliferation and self-renew ability and can be differentiated into neurons and glial cells. Mature nerve cells do not have proliferative ability; and due to the limited number of nerve stem cells, injuries to the nervous system are not recoverable. The purpose of this revi...

Introduction: To address the question whether combination of methylprednisolone (MP) as an anti-inflammatory drug used in neurodegenerative diseases and neural stem/progenitor cells (NS/PCs) is safe, the present study was designed. Methods: Embryonic rat NS/PCs were exposed to different concentrations of MP and survival by MTT assay, proliferation by analyzing the number and diameter of neuro...

BACKGROUND Incidence of urinary tract infections is elevated in patients with diabetes mellitus. Those patients show increased levels of the saturated free fatty acid palmitate. As recently shown metabolic alterations induced by palmitate include production and secretion of the pro-inflammatory cytokine interleukine-6 (IL-6) in cultured human bladder smooth muscle cells (hBSMC). Here we studied...

variety of positive as well as negative regulatory signals are provided by antigen presenting cell in particular by dendritic cells. in this research, we studied the capacity of dendritic cells to expand antigen-specific t regulatory cells.we also investigated the role of tgf-beta in induction inhibitory functions of dendritic cells in mixed leukocyte reactions. dendritic cells were generated f...
