Increased senescence and persistent DNA damage in bone marrow cells from Recql4HD mice. (a) Senescence of bone marrow cells from two pairs of sibling wild-type and RTS mice at the age of 4 months was measured by SA-β-gal staining. The bar indicates 150 μM. (b) Expression of p21 was investigated by western blotting. (c) DNA-SCARS were identified by immunostaining bone marrow cells with p53 and PML antibodies. The bar indicates 20 μM
