Abstract
This invention discloses an implant for regeneration of tissue with lesions, comprising a mixture with different types of cells, particularly, mesenchymal stem cells (MSC), endothelial cells, and specific functional cells according to the nature and function of the tissue, included into the biocompatible polymeric matrix, where the cells may or may not be organized in a specific way. This innovation also discloses a method to manufacture the implant. The implant of the present invention is useful for replacement or regeneration of animal and human tissues.
Claims8
A method for manufacturing a tissue regeneration implant, consisting of:
- scattering mesenchymal stem cells, endothelial cells selected from mesenchymal stem cells differentiated into vascular endothelial cells and cells obtained from a vascular endothelial tissue;
- and functional cells, wherein the functional cells are cardiomyocytes and wherein said cardiomyocytes are selected from mesenchymal stem cells differentiated into cardiomyocytes and cardiomyocytes obtained from a cardiac tissue;
- adding a precursor of a biocompatible re-absorbable polymeric matrix;
- and
- polymerizing the precursor to form a re-absorbable biocompatible polymeric matrix embedded with the mesenchymal stem cells, endothelial cells and functional cells, wherein the polymerization reaction is carried out in the presence of ammonium hydroxide vapor;
- and the re-absorbable biocompatible polymeric matrix comprises type 1 collagen.
