Morphology and viability evaluation of encapsulated hDPSCs using ALG and ALGPA. ALG- and ALGPA-encapsulated hDPSC morphologies were evaluated under light microscope a. The viability of encapsulated hDPSCs was also determined by alamarBlue™ assay b and live/dead staining c. The asterisks indicated significant difference, comparing with initial condition at 2 h (p < 0.05)
