Adhesion and Proliferation of Human Periodontal Ligament Cells on Poly(2-methoxyethyl acrylate)
Figure 6
Percentage of Ki-67-positive cells on polymer surfaces: (a) 1 day, (b) 3 days, and (c) 7 days. Polymers: PET, PMEA, and PHEMA. and versus PMEA, mean ± standard deviation, . (d)-(e) Classification of Ki-67 staining. The images show Ki-67 staining of PDL cells on PHEMA after 3 days. Scale bars: 100 μm. Blue: nucleus, green: Ki-67-positive cells. (d) CLSM images of PDL cells showing the nucleus and Ki-67 staining. (e) CLSM images of PDL cells showing Ki-67 staining. Types I and II: the Ki-67 antigen is present in the nucleus during the G1, S, and G2 phases of cell division and during mitosis. Type III: quiescent or resting cells in the G0 phase do not express the Ki-67 antigen.
