Abstract (original English)
Human mesenchymal stem cells have previously been isolated and characterized from the gingiva, and gingiva-derived stem cells have been applied for tissue engineering purposes. The present study was performed to generate size-controllable stem cell spheroids using concave microwells. Gingiva-derived stem cells were isolated, and the stem cells of 1×10 5 (group A) or 2×10 5 (group B) cells were seeded in polydimethylsiloxane-based, concave micromolds with 600 µm diameters. The morphology of the microspheres was viewed under an inverted microscope, and the changes in the diameter and cell viability were analyzed. The gingiva-derived stem cells formed spheroids in the concave microwells. The diameters of the spheroids were larger in group A compared to group B. No significant changes in shape or diameter were noted with increases in incubation time. Cell viability was higher in group B at each time point when compared with group A. Within the limits of the study, the size-controllable stem cell spheroids could be generated from gingival cells using microwells. The shape of the spheroids and their viability were clearly maintained during the experimental periods.
