Substantial Wnt-Responsive Cells Persist in the Hard Palate During and Post-Injury Healing

(A–D) Representative Masson trichrome staining showing the healed (A) hard palate and (B) soft palate on PSD7. Xgal staining was performed to detect the Wnt-responsive cells in (C) the healed hard palate and (D) the healed soft palate on PSD7.

(E-H) Representative Masson trichrome staining showing the healed (E) hard palate and (F) soft palate on PSD14. Xgal staining was performed to detect Wnt-responsive cells in (G) the healed hard palate and (H) the healed soft palate on PSD14.

(I) Xgal staining showing Wnt-responsive cells in the healed hard palate on PSD28.

(J) Quantification of Xgal^+ve cells in the hard and soft palates at indicated time points (n = 6, 5 sections of each mouse). Abbreviation: lp, lamia proper; PSD, post-surgery day. Scale bars: 100 μm.

Data represent mean ± SD. See also Figure S4.
