Fig. 4. Loss of RA curtails apoptosis in perioptic mesenchyme.
(A,B) Detection of phosphohistone 3 (H3P) in frontal sections of
E11.5 Raldh1-/- (A) and
Raldh1-/-;Raldh3-/- (B) eyes reveals
no difference in cell proliferation. (C,D) TUNEL assay in
frontal sections of E11.5 Raldh1-/- (C) and
Raldh1-/-;Raldh3-/- (D) eyes reveals
mesenchymal regions of apoptosis that are lost in the double mutant (arrows).
D, dorsal; V, ventral.
