Figure 7 Mesenchymal stem cells-derived dental pulp after (a) 24 h culture, (b) 48 h culture, (c) 72 h culture, and (d) 72 h culture (passage 1); black arrow represented the spindle-shaped cells. Black square represented the colony-forming unit with spindle cells emerged beneath it (scale bar: 50 μm).
