Development of chicken embryo HFR explant in culture. (A, left) Chicken embryo at 4 ss; (A, right); dissected heart forming region explant from 4–5 ss embryo; (B) 4–5 ss heart forming region explant after one day of cultivation in Endo-Grow medium. Red lines mark the borders of contractile tissue developed within a day in culture (see Additional file 1). Contractile tissues were observed by microscopy and documented using video camera. hfr, heart forming region; ss, somite stage. Scale bars, 1 mm.
