Morphological aspects of stem cells and pre-osteoblasts on tissue culture plate (a, a’, a”, a”’) and on bioceramics G20-40 (b, b’, b”, b”’ and c, c’, c”, c”’), in control media, at day 7. Under light microscopy, pre-osteoblasts (MG-63) had round-shaped morphology compared to stem cells (a, a’, a”, a”’). When seeded on the bioceramics, eventual distinct morphological features of the cells are not distinguishable (b, b’, b”, b”’, c, c’, c”, c”’). MSC mesenchymal stem cells, ADSC adipose-derived stem cells, DPSC dental pulp stem cells. Scale bars (SEM) 50 μm
