Dnmt3b hematopoietic stem cell

WebFeb 10, 2011 · Homing of hematopoietic stem/progenitor cells (HSCs) to their bone marrow niches is crucial to successful transplantation. This multistep process starts with rolling and tethering of HSCs to bone marrow sinusoidal endothelial cells, followed by migration through the endothelium and extracellular matrix barrier to engage their bone … WebTherefore we hypothesized that DNMT3b regulates hematopoietic stem cells via its ability to methylate DNA. By knock-down of DNMT3b with a retrovirally delivered shRNA or Cre mediated recombination of floxed DNMT3b alleles work presented in this thesis demonstrates a critical role for DNMT3b in hematopoiesis in mice.

Hematopoietic stem cells (HSCs) are essential for the maintenance of the hematopoietic system. However, these cells cannot be maintained or created in vitro, and very little is known about their generation during embryogenesis. Many transcription factors and signaling pathways play essential roles at various stages of HSC development. north edwards ca map
