STAT3 and STAT1 are differentially expressed during myogenic differentiation in human muscle cells. Graphs represent phosphorylated and endogenous levels of STAT3 (a, b) and STAT1 (c, d) in protein extracted from near confluent primary human myoblasts that were induced to differentiate during the specified times. Values are arbitrary units representing the mean of 6 replicates ± SEM. Significantly different from Pro: * p < 0.05, *** p < 0.001. Significantly different from Pro and Day 1: λ p < 0.05, λλ p < 0.01.
