Fig. 4. Normal hair growth in grafts of p107/p130-null epidermis. Growth of hair coat in the grafts from control (A') and p107/p130-doubly deficient mice (A) was evident four weeks after transplantation. Sections of skin grafts from p107/p130-doubly deficient mice (B,C') showed normal anagen hair follicles without alterations in any of the different epithelial layers (B) and hair bulbs (C') undistinguishable from those of control transplants (C). Scale bars: 50 µm.
