A),B),C) Primary calvarial cells and D),E),F) BMSCs stimulated with PBS, HD (Antennapedia Homeodomain), 40nM BMP2, and 100nM CK2.3. A),D) low resolution, B),E) high resolution of cells. C),F) Quantification of B),E). 3 independent experiments were performed. Statistically significant compared to (a) control, (b) HD, (c) BMP2, (d) CK2.3. (p< 0.05).
