Fig. 6 Csk acts upstream of Fyn and Yes in gastrulation cell movements. The Csk-MO (5 ng) was injected alone or together with human csk mRNA (150 pg) or low levels of Fyn/Yes-MO (0.125 ng each, low). As a control, high levels of Fyn- and Yes-MOs that induce CE defects were injected (5 ng each, high). The angle between the most anterior and posterior embryonic structure was determined at the 1-somite stage in at least 20 embryos and the average angle is depicted here in degrees. Two tailed student t-tests indicate a significant increase in the angle after injection of Csk-MO alone (P < 0.001, single asterisk) and a significant decrease in the angle after co-injection of csk mRNA or Fyn/Yes-MO (P < 0.001, double asterisk).
