Fig. 9. Model of Xvent gene action in response to different Bmp-4
concentrations. (Left) High Bmp-4 activity in lateroventral marginal
zone drive the expression of both Xvent genes. Sum of Xvent gene
activity is high and specifies cells as the most ventral type of
mesoderm: blood and mesenchyme, repressing muscle and
notochord. (Right) Low Bmp-4 activity in dorsolateral marginal zone
is not sufficient for Xvent-1 but for Xvent-2 expression. The sum of
Xvent gene activity is low and specifies cells as muscle, but represses
notochord. Image published in: Onichtchouk D et al. (1998) Copyright © 1998. Image reproduced with permission of the publisher and the copyright holder. This is an Open Access article distributed under the terms of the Creative Commons Attribution License. Larger Image Printer Friendly View |
