Fig. 8. Increased apoptosis in the hindlimbs of
Fgfr1Co/Co;Hoxb6-Cre mice detected by staining with
LysoTracker Red. Whole-mount images of E10.5 (A,B), E11.5 (C,D) and E12.5
(E,F) limbs. Arrows and arrowheads in mutant limbs indicate apoptotic cells.
The arrowhead marked with an asterisk in F indicates an apoptotic area that is
out of focus, but it was confirmed under the microscope. Wt, wild type; Mt,
mutant.
