  • Recombinant human PDGFbb (HZ-1308) stimulates dose-dependent proliferation of the NIH/3T3 mouse fibroblast cell line. Viable cell number was quantitatively assessed by Prestoblue Cell Viability Reagent. NIH/3T3 cells were serum starved with 0.1% FBS for 24 hours before treatment with increasing concentrations of recombinant human PDGFbb for 48 hrs. The EC50 was determined using a 4- parameter non-linear regression model. The EC50 values range from 0.3-3 ng/mL.

Background

PDGFbb is a member of the platelet-derived growth family factor. Four members of this family are mitogenic factors for cells of mesenchymal origin, and they are characterized by a motif of eight cysteines. PDGFbb is required for normal proliferation and recruitment of pericytes and vascular smooth muscle cells in the central nervous system, skin, and placenta among others. PDGFbb plays a role in blood vessel development. It also implements its role in wound healing (PMID: 29266203; 28851707; 28556368).
