Figure 3. Expression of Pax7 at 24h following heat shock induction of Bmp2b.

Figure 3

A. Expression of Pax7 (green) in embryos that were injected with the hs-bmp construct, but not heat shocked. Pax7 cells are distributed along the borders of the myotome and in the horizontal myosepta. Myosin is shown in red. B. Pax7 expression (green) in an embryo that was heat shocked at 8S to induce overexpression of BMP. The number of Pax7 expressing cells is increased in somites along the anterior-posterior axis. C. Pax7 expression in an embryo that was heat shocked at the 17S stage to induce overexpression of BMP. A strong increase in the number of Pax7 expressing cells is evident in the posterior somites, particularly around somite 17. There is also a smaller increase in the number of Pax7 expressing cells in the anterior portion of the somite. Numbers above somites indicate the number of Pax7+ nuclei in that somite. Scale bar: 50µm
