Fig. 6. (A,B) Evidence for stabilization of HIF1
in the Vhlh null
growth plate. Immunohistochemical detection of HIF1
in cryosections of
newborn control (A) and Vhlh null (B) proximal tibia growth plates.
(C-F) Evidence for an increased HIF1
activity in Vhlh null
growth plates. In situ hybridization analyses of histological sections of
proximal tibia growth plates from control (C,E) and Vhlh null (D,F)
newborns, with PGK (C,D) and VEGF (E,F) cRNA; darkfield images are shown.
