Three-Dimensional Bioreactor Technologies for the Cocultivation of Human Mesenchymal Stem/Stromal Cells and Beta Cells

Figure 1

Therapeutic effect of human mesenchymal stem/stromal cells (hMSCs) in the context of beta cell engraftment. Human MSCs modulate the host immune systems, for example, by secreting various trophic factors. Therefore, they prevent rejection of allogenic beta cell grafts and improve the survival of the graft by promoting neoangiogenesis at the transplant site and prevent apoptosis and fibrosis. ┤ inhibition, → improvement.
