Fig. 3From: Prolyl hydroxylase domain 2 deficiency promotes skeletal muscle fiber-type transition via a calcineurin/NFATc1-dependent pathway Phd2 deletion induces angiogenesis in skeletal muscle. a The VEGF level in skeletal muscle was measured by ELISA (n = 3 per group). b Relative gene expression was measured using gastrocnemius muscle tissue cDNA (n = 3 per group). c, d The capillary density in skeletal muscles was determined by detecting CD31-positive cells using immunostaining (n = 5 per group). *p < 0.05, compared to control. Values are means ± SEM (scale bar = 100 μm)Back to article page
