摘要:
The present invention provides a preparation method of a three-dimensional construct for regenerating a cardiac muscle tissue comprising a step of forming a three-dimensional construct by printing and crosslinking the first bioprinting composition comprising a tissue engineering construct forming solution containing decellularized extracellular matrix and a crosslinking agent, and cardiac progenitor cells, and the second bioprinting composition comprising the tissue engineering construct forming solution, mesenchymal stem cells and a vascular endothelial growth factor, to arrange the first bioprint layer and the second bioprint layer alternately and a step of obtaining a crosslink-gelated three-dimensional construct by thermally gelating the crosslinked three-dimensional construct, and a three-dimensional construct for regenerating a cardiac muscle tissue, and the preparation method according to the present invention not only equally positions the cardiac progenitor cells in the construct but also implements a vascular network composed of vascular cells in the construct, so that the viability of cells can be maintained for a long time and the cell transfer efficiency into the myocardium can be significantly improved.
