Usage

Uses

Pyrintegrin enhances the survival of Human embryonic stem cells (hESC).

Biological Activity

pyrintegrin, a 2,4-disubstituted pyrimidine, is a novel small-molecule inhibitor of bmp signaling which previously found to promote human embryonic stem cells survival [1].bone morphogenetic proteins (bmps) are members of the tgf-β superfamily of secreted signaling molecules with important roles in many biological contexts. bmps could bind to specificserine/threonine kinase receptors and transduce the signal to the nucleus through smad proteins [2].

in vitro

pyrintegrin induced differentiation of hadscs into adipogenic‐like cells in vitro. pyrintegrin drug treatment can accelerate adipocyte differentiation and augment lipid accumulation, adiponectin and fatty acid secretion in adipogenic medium differentiated human adipose derived stem cells [1]. pyrimidine (2 μm) enhanced the survival of hesc more than 30-fold after trypsin-mediated dissociation. pyrimidine increased integrin-dependent attachment of hesc to extracellular matrices without significantly impacting cell proliferation. pyrintegrin increased the binding of the activated β1 integrin-specific antibody huts-21 and enhanced the phosphorylation of multiple growth factor receptors and their downstream kinases, pi3k and mapk [3].

in vivo

pyrintegrin promoted proliferation and differentiation of adipose precursor cells depending on their microenvironment. pyrintegrin increased the number of preadipocytes and the rate of adipocyte differentiation, resulting in enhanced de novo adipogenesis [1].
