Abstract (original English)
The purpose of this study was to identify the effect of collagen-alginate composition on the size and shape of microbeads and the proliferation and osteogenic properties of microencapsulated canine adipose-derived mesenchymal stem cells (ASCs) in vitro. Canine ASCs were microencapsulated in mixtures of various collagen-alginate compositions using a vibrational technologic encapsulator. The size and shape of the resultant microbeads were measured using a light field microscope and the viability of the microencapsulated canine ASCs was evaluated using a live/dead viability/cytotoxicity kit. Proliferation and osteogenic potentials of microencapsulated canine ASCs were evaluated using an alamarBlue proliferation assay and an alkaline phosphatase assay, respectively. As the collagen ratio increased, the size and size variation of microbeads increased and the shape of microbeads became more irregular. Nonetheless, homogeneous microbeads were created with no significant difference in size and shape, in the range of 0.75% alginate mixed with 0.099% collagen solution in 1.2% alginate solution. There were no significant differences in viability of the ASCs in the various collagen-alginate compositions. Both proliferation and osteogenic properties, in vitro, increased with increasing collagen ratio. Microencapsulation of canine ASCs with appropriate collagen-alginate composition increases
