摘要:: Many cell therapy approaches aim to deliver high-density single-cell suspensions to diseased or injured sites in the body. Long term clinical success will in part be dependent on the cells that remain viable and that assume correct functionality post-administration. The research presented in this paper focuses on the potential of cell aggregate delivery to generate a more supportive environment for cells than single cell suspensions. An in vitro model of injection delivery of C2C12 myoblast cells showed a significant difference in cell function and phenotype between adhesive collagen and non-adhesive alginate, indicating that in vitro assays based on this approach can discriminate between cell-cell/cell-matrix interactions and could be valuable when assessing cell therapy systems. Contrary to single cells, aggregates maintain viability, cellular activity, and phenotype beyond that of single cells, even in non-adhesive matrices, enabling delivery of higher cell densities with enhanced proliferative and differentiation capacity.
