FIG. 7.

Gene expression of early and later stage osteogenic markers in growth media and osteogenic media through 2 weeks relative to day 0. hMSCs were cultured on polyHIPEs with no particles, ACP, or HA in growth media (GM) and no particle control polyHIPEs in osteogenic media (OM). (A) Runx2 and ALP expression, (B) osteopontin (OPN), collagen type I (Col1a1), and osteocalcin (OCN) expression. * indicates significance between marked with an asterisk or all other groups in the case where only one group is marked. o indicates significance between groups marked with the same symbol (o).
