Bone progenitor dysfunction induces myelodysplasia and secondary leukemia


CD45 CD31 GFP + osteolineage cells in bone marrow (a) or collagenased bone fragments (b) (n=4) c-e impaired osteogenic differentiation capacity of OCD fl/fl bone marrow stromal cells as shown by reduced CFU-Alk/CFU-F ratio (c) (n=2, performed in quadruplicate), impaired in vitro osteogenic differentiation upon osteogenic induction (d) and decreased osteocalcin gene expression in primary osteolineage cells as shown by RT-PCR on CD45 Lineage CD31 GFP+ cells (n=5) (e) f, altered texture of the bone matrix g, normal trabecular bone volume (BV) and h, increased cortical bone volume as assessed by histomorphometric analysis (n=8)(TV=total volume; BA=bone area, TA total area). i,j reduced osteoblasts (Ob) number per bone surface (Bs) in OCD fl/fl mice as indicated by histomorphometric analysis (n=8) k, the number of osteoclasts (OC) was unaltered in OCD fl/fl mice (n=8). Data are mean ± s.e.m. * p≤0.05, **p≤0.01. CFU-F=colony-forming assay –fibroblast, CFU-ALK=colony forming unit alkaline phosphatase, AP=alkaline phosphatas i
