Understanding how interactions between extracellular signalling pathways and transcription factor networks influence cellular decision making will be crucial for understanding mammalian embryogenesis and for generating specialised cell types in vitro. To this end, pluripotent mouse Embryonic Stem (mES) cells have proven to be a useful model system. However, understanding how transcription facto...

The mitochondrion is emerging as a key organelle in stem cell biology, acting as a regulator of stem cell pluripotency and differentiation. In this study we sought to understand the effect of mitochondrial complex III inhibition during neuronal differentiation of mouse embryonic stem cells. When exposed to antimycin A, a specific complex III inhibitor, embryonic stem cells failed to differentia...

hippocampal neural stem/progenitor cells (hipp-ns/pcs) of the adult mammalian brain are important sources of neuronal and gial cell production. in this study, the main goal is to investigate the plasticity of these cells in neuronal/astroglial differentiations. to this end, the differentiation of the hipp-ns/pcs isolated from 3-month-old wistar rats was investigated in response to the embryonic...

the stem cells can be considered as the miracle of creation, because, they are a major reservoir of the bioactive factors, molecules and cells. these reservoir cells play a major role in development and growth of the tissues and organs. regardless of the differences in differentiation capacity of embryonic and adult stem cells, both the cells are rich sources of stem cells with therapeutic appl...

background: specific growth factors and feeder layers seem to have important roles in in vitro embryonic stem cells (escs) differentiation. in this study,the effects of bone morphogenetic protein 4 (bmp4) and mouse embryonic fibroblasts (mefs) co-culture system on germ cell differentiation from mouse escs were studied. materials and methods: cell suspension was prepared from one-day-old embryoi...

With recent findings on the role of reprogramming factors on stem cells, in vitro screening assays for studying (de)-differentiation is of great interest. We developed a miniaturized stem cell screening chip that is easily accessible and provides means of rapidly studying thousands of individual stem/progenitor cell samples, using low reagent volumes. For example, screening of 700,000 substance...
