The cells lining the surface of trabeculae in the HuO9 tumour were positive for Alu, but a few of them were also positive for m-L1. The m-L1-positive cells expressed mouse osteocalcin and type 1 collagen mRNAs. Sep 2, 2011 · Figure 1. The origin of bone. Precipitation of hydroxyapatite around the basal membrane of the skin gave rise to enamel- and dentine-like tissues that formed odontodes, which became the progenitors of teeth and scales. Spread of mineralization deeper in the dermis formed shields consisting of acellular—and later cellular—bone. Those are ensheathed by osteoid produced by osteoblasts, thus forming the bone trabeculae of the primary spongiosa. Based on previous lineage tracing experiments it was concluded that the spongiosa forming osteoblasts originate from invading, periosteum-derived osteoprogenitor cells (Colnot et al., 2004; Maes et al., 2010).A.
