Background and purpose: The use of an appropriate stimulus for increasing the rate of neural stem cell proliferation is one of the most important issues in cell therapy. This study aimed to investigate the effect of hydroethanolic extract of Stachys byzantina on hippocampus-derived neural stem cell proliferation and apoptosis. Materials and methods: In this experimental study, the neural ste...
Background: Expansion of the use of magnetic fields in metals, mining, transport, research, and medicine industries has led to a discussion about the effects of magnetic fields and whether their strength is negligible. The aim of this study was to investigate the effects of magnetic field on the viability and proliferation rate of HeLa cells. Materials and methods: We studied the effects of ma...
BACKGROUND Much is known about how cell proliferation is controlled at the single cell level, but much less about the control of cell numbers in developing populations. Cell number might be determined by an intracellular division limiter or, alternatively, by the availability of mitogens or other factors outside the cell. We investigated the relative importance of intracellular and extracellula...
Cytotoxic cancer chemotherapy drugs are believed to gain selectivity by targeting cells that proliferate rapidly. However, the proliferation rate is low in many chemosensitive human cancers, and it is not clear how a drug that only kills dividing cells could promote tumor regression. Four potential solutions to this "proliferation rate paradox" are discussed for the microtubule-stabilizing drug...
