text: Cdk inhibitors expression is elevated in senescent cells,25 and this together with the cell morphology of Cre-infected osteoblasts made us assay for the presence of senescence-associated β-galactosidase (SABG) that is considered to be a hallmark of senescence.26 Cre-infected osteoblasts stained positive for SABG, whereas Sox2-transduced cells did not, indicating that loss of Sox2 might produce a phenotype akin to senescence in osteoblasts (Figure 4d).
