Expression of PDGF receptors in proliferating and involuting hemangiomas. (a) Real-time RT-PCR analysis of PDGFR-α, -β, and PPARγ in proliferating and involuting hemangiomas (data normalized to 18S rRNA and presented as relative to normal skin; *P<0.05 compared with normal skin, †P<0.05 compared with proliferating hemangioma; n=3). (b) Immunostaining of proliferating hemangiomas for PDGFR-α and PDGFR-β (images taken at × 20, inserts show higher magnification; brown=DAB staining, blue=hematoxylin). (c) Immunofluorescence double labeling for mesenchymal cell marker α-SMA and PDGFR-β (images taken at × 20, green=PDGFR-β, red=α-SMA)
