UMR106-01 cells as well as primary calvarial bone cells assembly spherical extracellular supramolecular protein-lipid complexes, termed biomineralization foci (BMF), in which the first crystals of hydroxyapatite mineral are deposited (Midura et al., 2004; Wang et al., 2004). A major difference between these culture models is the speed with which mineralization occurs, ranging from 12–16 days after plating for primary osteoblastic cells to 88 h for UMR106-01 cells. https://www.leica-microsystems.com//science-lab/dry-ultrathin-sectioning-combined-with-high-pressure-freezing/ Mon, 10 Dec 2012 23:00:00 +0000 Ph.D. Jeff P.
