Figure 6

Phase contrast microscopic images of human bone marrow mesenchymal stem cells (hBMMSCs) following exposure either as cell suspension arm (A) or cell pellet arm (B) to illuminated arthroscopic temperature and cultured for 72 h. Decrease in cell density was observed in cell suspension arm (A) compared to cell pellet arm (B). (Magnification 10X). (C,D) Cellular activity assay of the hBMMSCs exposed to an illuminated arthroscope at 72 h, either as cell suspension (C) or cell pellet (D). Values are expressed as mean ± standard error of the mean (SEM) from three different samples. Asterisks (*) indicate statistical significance at p < 0.05 compared to respective controls.
