Figure 1

Microscopic analysis of dental pulp and amniotic fluid stem cells cultured in collagen scaffolds. 6-Carboxyfluorescein diacetate-stained cells present in (A) dental pulp stem cell–collagen and (B) amniotic fluid stem cell–collagen constructs after 7 days of culture were analyzed by in vivo confocal microscopy. Confocal images of cells (green) were superimposed to differential interference contrast images of scaffolds (gray). Scale bar = 20 μM.
