Caspase-12 protein in perinatal and postnatal development. Immunofluorescence analysis of caspase-12 (green) in mandibular bone and the first lower molar at perinatal stages (E18 and P1) and postnatal stage P12. Caspase-12 was localized in the mandibular bone, predominantly in osteoblasts (A,C,E) at all of these stages. In the developing tooth, caspase-12 was positive mainly in ameloblasts and odontoblasts (B,D,F). Scale bar: 100 μm, counterstained by DAPI (blue). White arrows point to osteoblasts, a red arrow points to osteoclasts. mb, mandibular bone; si, stratum intermedium; sr, stellate reticulum; dp, dental pulp; am, ameloblasts; od, odontoblasts.
