Basic differences between the cells from the alveolar bone and long bones. Light microscopy of (A) the alveolar bone cells and (B) the long bone cells at day 7. (C) DNA content, as a measure of the number of cells at a given time point, of both cells derived from alveolar bone and the long bone at day 0, day 7, day 14 and day 21. To gain insight into the osteogenic lineage of both cell types, the gene expression of osteogenic genes was assessed at day 0 (D–H) The relative expression of both (D) Col1a and (E) RUNX2 was comparable in both the alveolar bone cells and the long bone cells. The relative expression of (F) OPN, (G) DMP-1 and (H) ACTA1 was significantly higher at day 0, in long the bone cells compared to the alveolar bone cells. Significance for DNA was measured using 2-way ANOVA with Bonferroni post-tests. For the relative gene expression, significance was measured using a t-test. * p < 0.05, ** p < 0.01.
