FGF2 isoform abundance and FGF2 mRNA expression in bone marrow (A) and in aorta (B) from Fgf2^+/+ mice A: Representative Western blot analysis showed that E₂ increased both FGF^lmw and FGF^hmw (quantification was the sum of 21- and 22-kd bands, performed on four separate Western blots) isoforms in BM homogenates. In contrast, abundance of FGF2 mRNA in BM was decreased by E₂. *P < 0.05 versus respective placebo. B: Quantification of Western blot showed that only FGF2^hmw isoform are increased in aorta homogenates. *P < 0.05 versus respective placebo.
