Figure 4. Early changes in differentiation following overexpression of Bmp2b.

Figure 4

A. Expression of pax3 in a 12S non-heat shocked control embryo. Pax3 is expressed by the anterior border cells (ABCs). B. Expression of Pax3 at 12S following heat shock induction of Bmp2b overexpression at 3S. pax3 expression is no longer confined to the anterior cells, and is expressed throughout the somite. C. Expression of myoD in a 12S non-heat-shocked control embryo. Myod is expressed throughout the posterior somite, and excluded from the ABCs. D. Expression of myoD at 12S following heat shock induction of Bmp2b overexpression at 3S. The domain of myoD expression is decreased. Red dots indicate somite boundaries. Scale bar: 50µm
