Abstract |
The negligible self-repair potential of the myocardium has led to cell-based tissue engineering approaches to restore heart function. There is more and more consensus that, in addition to cell development, paracrine effects in particular play a pivotal role in the repair of heart tissue. Here, we present two complementary murine P19 and P19CL6 embryonic carcinoma cell-based in vitro test approaches to study the potential of repair cells and the factors secreted by these cells to induce cardiomyogenesis. P19 cells were 3-dimensionally cultured in hanging drops and P19CL6 cells in a monolayer. Both systems, capable of inducible differentiation towards the cardiomyogenic lineage shown by the appearance of beating cells, the expression of connexin 43 and cardiac troponins T and I, were used to test the cardiomyogenesis-inducing potential of human cardiac-derived adherent proliferating (CardAP) cells, which are candidates for heart repair. CardAP cells in coculture as well as CardAP cell-conditioned medium initiated beating in P19 cells, depending on the cell composition and concentration of the medium. CardAP cell-dependent beating was not observed in P19CL6 cultures, but connexin 43 and cardiac troponin formation as well as expression of GATA-binding protein 4 indicated the dose-dependent stimulatory cardiomyogenic effect of human CardAP cells. In summary, in different ways, P19 and P19CL6 cells have shown their capability to detect paracrine effects of human CardAP cells. In a complementary approach, they could be beneficial for determining the stimulatory cardiomyogenic potential of candidate cardiac-repair cells in vitro.
