IGFBP2 and ischemia: PDGF-D stimulation enriches the secretome of pericytes exposed to ischemia and reperfusion-like conditions by molecules involved in mediating vascular remodeling, namely IGFBP1, uPA, and VEGF, while reducing the expression of molecules involved in inhibiting angiogenesis, namely TSP1, IGFBP2, and serpin E1.
