Figure 2. "Apoptotic" effects of TEGDMA on HGF. Fibroblasts were stained with APOPercentage^TM for 1 hr. (A,D) Untreated control cultures; no apoptotic cells are visible. Cells exposed for 24 hrs to TEGDMA: (B) 2.5 mM and (C,E) 7.5 mM TEGDMA. Apoptotic cells are stained intensely red (A-C bar = 22 µm; D,E bar = 5.5 µm).
