RGS-5 expression during physiologic neovascularization. (A-B) Consecutive frozen tissue sections of a mouse ovary stained with (A) hematoxylin and eosin or (B) after in situ hybridization with a RGS-5–specific riboprobe (f indicates follicles; original magnification × 12.5). (C) Relative RGS-5 expression levels during dorsal wound healing. RNA from 5 to 9 independent samples of untreated skin (control) and wounds at days 1, 3, 6, 9, and 14 was quantified by RT-PCR.
