一般說明
PDGFs (platelet-derived growth factors) are disulfide-linked dimers consisting of two 12.0-13.5kDa polypeptide chains, designated PDGF-A and PDGF-B chains. Two distinct signaling receptors used by PDGFs have been identified and named PDGFR-α and PDGFR-β. PDGFR-α is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR-β interacts with only PDGF-BB and PDGF-AB. Recombinant murine PDGF-BB is a 24.4kDa disulfide-linked homodimer of two B chains (218 total amino acids).
應用
PDGF-BB from mouse has been used as a chemotactic factor on vascular smooth muscle cell.
生化／生理作用
The three naturally occurring PDGFs (platelet-derived growth factors); PDGF-AA, PDGF-BB and PDGF-AB, are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. The PDGFs are stored in platelet α-granules and are released upon platelet activation. The PDGFs are involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. Heterozygous mutation in PDGFB is associated with primary familial brain calcification. It is also associated with angiogenesis for osteogenesis. PDGFB induces migration of endothelial progenitor cells and mesenchymal stem cells.

重構
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Inhibition of vascular smooth muscle cell (VSMC) proliferation by drug eluting stents has markedly reduced intimal hyperplasia and subsequent in-stent restenosis. However, the effects of antiproliferative drugs on endothelial cells (EC) contribute to delayed re-endothelialization and late stent thrombosis. Cell-targeted
