MyHC transcripts in developing human skeletal muscle. The transcripts were revealed by in situ hybridization using probes specific for the following MYH genes: MYH3 (Emb, a–d), MYH8 (Neo, e–h), MYH7 (Slow, i–l), MYH2 (2A, m–p), and MYH1 (2X, q–t). Muscles examined were quadriceps femoris from 9 and 19-week-old fetuses and vastus lateralis from 1-day- (P1) and 1-month-old (P30) newborns. Bar = 30 μm (from [48])
