(A,B) E8.25 HopxERCre/+; R26Tom/+ embryos were induced with tamoxifen and harvested at E9.5 (A) and E18.5 (B). Individual Hopx-derived cells are labeled at E9.5 (A, B area highlighted by arrowhead is magnified on right). At E18.5, clusters of myocytes are identified (B). (C,D) HopxERCre/+; R26Tom/+ embryos were induced with tamoxifen at E8.25 (C) or E9.25 (D) and analyzed at E18.5 (n ≥ 2 litters per time point, 2 examples at each time point shown). Scale bars: 500 µm (C,D) and 50 µm (A,B).
