Figure 3

The spatial structure of developing microtissues pre-exposed to TEGDMA prior to treatment with NAC. (A) Schematic diagram of the experimental assay. (B–M) Confocal images of (B–G) hpDPSC and (H–M) hiDPSC microtissues (B,E,H,K) non-exposed versus exposed to (C,F,I,L) moderate and (D,G,J,M) high concentrations of TEGDMA before (E–G,K,L,M) treatment with NAC. (N–O) Bar graphs comparing the thickness of the (N) hpDPSCs and (O) hiDPSCs structures non-treated vs. treated with NAC. * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001.
