Fig 1: Myostatin treatment negatively regulated prominent osteogenic gene expression. Heat maps showing the osteogenic gene expression of preosteoblast cells cultured in growth media supplemented with myostatin, follistatin, or a combination of both for (A) 48 hours and (B) 7 days. MSTN = myostatin; FST = follistatin. All gene expressions were normalized to no‐treatment control and housekeeping gene Gapdh expression. n = 3 for all groups.
