Transgene expression in the forming chicken embryo. Transgenic and control embryos were stained for of β-galactosidase activity. A) Transgenic and (B) control embryos at day 3 of development. C) Higher magnification of the embryo in (A) to show staining in the forming myotome. D) Transcripts from the endogenous locus at day 3 are revealed by in situ hybridisation for both MLC1 and 3. E) Transgenic and (F) control embryos at day 10 of development. Arrow, myotome.
