TERC and aplastic anemia: Aplastic anemia has been also associated to telomere shortening in both humans and mouse models (Siegl‐Cachedenier et al., 2007); however, blot tests and bone marrow examination did not evidence severe aplastic anemia either in TERC−/− p66SHC+/+ or TERC−/− p66SHC−/− mice (Fig. 5B).
