Resumo
Highly porous cylinder-shaped 3D matrices with diameters of 1.3 and 3 mm were obtained by lyophilization of collagen solution. A study in vivo of the mechanism and rate of resorption of the resulting material showed that complete resorption of the matrix occurred 6 weeks after their implantation into liver tissue and 3 weeks after implantation into muscle tissue of animals. Surrounding tissues were not altered or damaged. Histological analysis revealed that, simultaneously with the resorption of matrix collagen, connective tissue and blood vessels were formed. This allows us to recommend the developed porous material based on collagen for use as matrices for tissue engineering and cellular transplantation.
