FIG. 3.

Cell morphology in regular cell culture medium and after addition of growth factors. The upper panel shows DPSC in cell culture medium without supplements (A), and after addition of FGF2 (B), or TGFβ1 (C). Culture medium was changed every other day, and growth factors were replenished. Cellular morphology changes from spindle shaped to narrow and elongated with FGF2 or large and flat with TGFβ1. The lower panel shows DPSC in presence of MDP hydrogels in inserts, either without growth factors (D), with FGF2 (E), or TGFβ1 (F). Analogous changes in morphology can be observed compared with the control panel just described. DPSC, dental pulp stem cell; MDP, multidomain peptide.
