The markers of mechanical sensation and osteogenic differentiation in the mandibles with disabled tendons and masseters. a–f The immunostaining of Yap in E13.5 WT (a) and Osr2-cre; Rosa26R-Fgf8 mandibles (b), E13.5 WT (c) and Osr2-cre; Rosa26R-DTA mandibles (d), as well as E13.5 WT (e) and Myf5-cre; Rosa26R-DTA mandibles (f). (g, g’, h, h’, i, j) The immunostaining of p-Erk1/2 in E13.5 WT (g) and Myf5-cre; Rosa26R-DTA mandibles (h), as well as E13.5 WT (i) and Osr2-cre; Rosa26R-DTA mandibles (j). The boxed areas in g and h were amplified in g’ and h’, respectively. k, l, m, m’, n, n’ The immunostaining of p-Smad1/5/8 in E13.5 WT (k) and Osr2-cre; Rosa26R-Fgf8 mandibles (l), as well as E13.5 WT (m) and Myf5-cre; Rosa26R-DTA mandibles (n). The boxed areas in m and n were amplified in m’ and n’, respectively. o, o’, p, p’, q, r The immunostaining of Osterix in E13.5 WT (o) and Osr2-cre; Rosa26R-Fgf8 mandibles (p), as well as E13.5 WT (q) and Myf5-cre; Rosa26R-DTA mandibles (r). The boxed areas in o and p were amplified in o’ and p’, respectively. Red dashed lines encircled masseters, blue dashed lines encircled mandibular bones, and the black dashed lines encircled masseter tendons; the red arrowheads pointed to the periosteal mesenchyme of mandibular bones; Scale bars: 200 μm
