The differentiation of murine proadipocytes can be induced by two different methods: 7.) by culture of high-density proad ipocytes in medium containing high concentrations of serum to which is added a variety of hormones and 2.) by culture of lowdensity proadipocytes in heparinized medium containing only human plasma. Phorbol myristate acetate influences differen tiation in both culture systems...

  Objective(s): Stem cell differentiation into different cell lineages depends upon several factors, cell cycle control elements and intracellular signaling elements, including P15INK4b and P16INK4a genes. Epigenetics may be regarded as a control mechanism which is affected by these factors with respect to their promoter structure.   Materials and Methods: The CD34 + cord blood s...

s:1846:"Reproductive health is only a small part of a series of interconnected it is considered necessary for the subject to come around or to take account of women arises. Reproductive health from the perspective of the International Conference on Population and Development in Cairo, was defined solely from the perspective of biology. Reproductive health was based on the view of "health for al...

This paper offers four main arguments about the nature of causation in the social sciences. First, contrary to most recent work, I argue that there is a unitary conception of causation: a cause raises the probability of an event. This understanding of causation, borrowed from but not wedded to Bayesian inference, provides common semantic ground on which to base a reconstruction of causation. I ...

background: several influential factors such as transcription factors and intracellular signaling components are involved in differentiation of stem cells into a specific lineage. p15 and p16 proteins are among these factors. accumulating evidences has introduced the epigenetic as a master regulator of these factors during lineage specification. the main objective of this study is to determine ...

biomolecular behavior of tumor cells has become attractive to investigators. p53 as an oncosuppresor gene has been core of various studies and ki67 is a nuclear protein involved in proliferation process. stopping of onco-suppressor function theoretically allows proliferative system to get out of any control. in this case-control study we evaluated 50 patients with non small cell lung cancer, co...

background: the mechanism of cadmium induced osteoporosis is not well understood, so in this study, we examined the toxicity of bone marrow mesenchymal stem cell (mscs) following treatment of rats with cdcl2 in drinking water, to revile the effect of this chemical on differentiation potential of mscs. methods: at the end of third passage, mscs were grown in the osteogenic medium for 21 days. to...
