Figure 1From: Proliferating and differentiating effects of three different growth factors on pluripotent mesenchymal cells and osteoblast like cellsa) Cell count of the osteoblast like cell culture treated with different growth factors. The data presented are normalized to the control group (PDLLA) which is set 100%. A significant increase in the cell number was seen after treatment with PDGFbb or IGF-I (days 2–10) in comparison to the PDLLA treated cells (ANOVA, Dunnett). b) Alkaline phosphatase activity (AP) of the osteoblast like cell culture treated with different growth factors. The data presented are normalized to the control group (PDLLA) which is set 100%. A significant increase in AP activity was seen after treatment with BMP-2 (days 5–15) in comparison to the PDLLA treated cells (ANOVA, Dunnett).Back to article page
