Fig. 2. Cell death and division in the forebrain are unaffected in embryos injected with Fgf morpholinos. (A-D) Dorsal views of the anterior neural plate at tailbud stage. Numbers of dividing cells within presumptive forebrain region (indicated by the rectangles) were counted and subjected to Student's t-test analyses. (E-H) Lateral views of whole-mounted 10s embryos, with anterior to the left, showing dividing cells. (I-L) Occasional apoptotic cells (arrowheads) detected dorsally in 10s embryos injected with control morpholino (I), Fgf8mo (J), Fgf3mo (K), or Fgf8 and Fgf3mo together (L). (M-P) Little cell death is detected in anterior neural tissue in 24 hpf embryos injected with control mo (M), Fgf8mo (N), Fgf3mo (O), or Fgf8 and Fgf3mo together (P).
