Introduction: Hematopoiesis is an on going process mammalian marrow system. A few cells from the nucleated cells of bone marrow are hematopoietic cells which include primary stem cells, precursor cells and progenitor cells. Primary stem cells and progenitor cells are able to produce colonies in culture medium (CFU-C) and irradiated mouse spleen (CFU-S). A hematopoietic cell is alive and act...
Abbreviations: Ad: adenovirus, bFGF: basic fibroblast growth factor, BMP: bone morphogenetic protein, CNS: central nervous system, ES: embryonic stem, FACS: fluorescence activated cell sorting, HIV: human immunodeficiency virus, ICM: inner cell mass, LIF: leukemia inhibitory factor, MEF: mouse embryonic fibroblast, RNAi: RNA interference, SCNT: somatic cell nucleus transfer, UTR: untranslated r...
stem cells are the cells having some distinguishing characteristics like longevity, high capacity of self-renewal and differentiation, quiescence and highly error-free proliferation. almost all stem cells have the potential of lineage reprogramming, i.e. inter-conversion of cell lineages. they also have the potential to differentiate into almost all kinds of cells. these cells have been found i...
background the mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. this source of stem cells avoids invasive procedures and the ethical controversy of embr...
Mouse epiblast stem cells (EpiSCs) are cultured with FGF2 and Activin A, like human embryonic stem cells (hESCs), but the action of the associated pathways in EpiSCs has not been well characterized. Here, we show that activation of the Activin pathway promotes self-renewal of EpiSCs via direct activation of Nanog, whereas inhibition of this pathway induces neuroectodermal differentiation, like ...
Embryonic stem cells (ESCs) are derived from the inner cell mass (ICM) of an embryo at the blastocyst stage. They are characterised by the ability to proliferate indefinitely (or selfrenew) in vitro while maintaining pluripotency, i. e. the capacity to differentiate into germ cells and a broad number of cell types that originate from the three primary germ layers endoderm, mesoderm and ectoderm...
objective: vitrification has been shown as one of the most effective methods of cryopreservation for mammalian embryos. however, there is no consensus which stage of embryonic development is the most appropriate for vitrification with subsequent maximal development after thawing. this study was carried out to explore and compare the effect(s) of vitrification on mouse 2-cell, 4-cell, 8-cell, mo...
BACKGROUND AND PURPOSE In humans and rodents, cortical stroke can lead to cortex atrophy in long-term survivors. In the rodent, fetal brain neural precursors or stem cell-derived neurons grafted in the stroke-lesioned brain integrate successfully and reduce infarct in the short term. We have examined the fate, in the long term, of mouse embryonic stem cell-derived neural precursors grafted afte...
