Fig. 4. Altered epidermal differentiation in Rb-deficient skin. (A-D)
Double-immunofluorescence on P10 skin sections showing K5 (green) and K10
(red) or (E-H) K6 (green) and K10 (red) of RbF19/F19
(A,E), RbF19/F19;K14cre (B,F),
RbF19/F19;p107+/;K14cre
(C,G) and
RbF19/F19;p107/;K14cre
(D,H). Yellow staining indicates co-expression. DAPI (blue) was used to stain
nuclei. Scale bars: 50 µm.
