Safranin O staining of the growth plate in PKC-δ+/+ and PKC-δ−/− mice. (A, B) Slightly weaker staining of safranin O was found in PKC-δ−/− mice; no significant difference in the height of the growth plate was found between PKC-δ+/+ and PKC-δ−/− mice as measured by safranin O staining regions. (C) Measurement of the height of growth plates by safranin O staining regions in PKC-δ+/+ and PKC-δ−/− mice. (TIFF 1716 kb
