Figure 2. Growth of hair follicles in wildtype and Msx2-cre; Kras^G12D mice.

(A) Cleared P4 whole skin of wildtype and Msx2-cre; Kras^G12D mice, demonstrating hair shaft and hair follicles. (B) Tracings of example complete hair shaft and follicles from cleared P4 skin. Asterisks indicate broken hair shafts, which were excluded from analysis. Scale bar =100 μm. (C) Plot of average length of P4 vs. P7 hair shafts from wildtype and Msx2-cre; Kras^G12D mice, representing at least four mice per age. (D) Summary of change in hair length between P4 and P7 in wildtype and Msx2-cre; Kras^G12D mice and statistical significance.
