Abstract (original English)
Cells, scaffolds, and growth factors are the three main factors for creating a stem-cell-based tissue-engineered construct, but the interactions between three factors are not very clear. We hereby explored the interactions between rat-adipose-derived stromal cells (rASCs), recombinant human bone morphogenetic protein-2 (rhBMP-2), and beta-tricalcium phosphate (beta-TCP) to provide evidence for their application in bone tissue engineering by evaluating the protein adsorption of beta-TCP, the cell attachment, alkaline phosphatase (ALP) activity/protein, osteocalcin (OCN) content, mineral formation, calcium content, phosphonium content, cell vitality, gene expression, and implantation in the backs of severe combined immunodeficient mice of rhBMP-2 preinducing rASCs seeded onto beta-TCP. The results showed that beta-TCP could adsorb the proteins from the media. The attachment, proliferation, and osteogenic properties of rASCs were supported by beta-TCP, as revealed using scanning electron microscopy. Compared with rASCs cultured on the culture plate, rASCs cultured on beta-TCP had significantly higher ALP activity/protein, OCN content, and mineral formation. These values for rASCs cultured on beta-TCP with rhBMP-2 increased most significantly. The rhBMP-2 significantly increased the calcium content, phosphonium content, and ALP, type I collagen, and OCN mRNA levels of rASCs culture
