Representative staining of nestin and periostin in femur sections from 8-day-old wild-type and Dnmt2−/− mice. The anti-periostin staining is comparable in the periosteum of wild-type and Dnmt2−/− mice, but is reduced in the bone marrow cells (compare the highlighted areas). Scale bar: 100 μm. Nuclei are counterstained with DAPI (blue).
