23 Jul Preparation method and device for artificial blood vessels
Abstract
The invention discloses a preparation method and device for artificial blood vessels and belongs to the technical field of tissue engineering. According to the method, firstly, repeated subculture is performed on blood vessel seed cells taken from a patient, so that the quantity requirement is met; then a cell suspension, ion concentration sensitive material-containing sodium alginate and a cell adhesive growth-promoting biodegradable material are mixed in a specific mass ratio; finally, a mixed solution containing the blood vessel cells, sodium alginate, the cell adhesive growth-promoting biodegradable material and the like is subjected to extrusion forming in a 0.5% CaCl2 solution by a self-made device, and artificial blood vessel unit prototypes having certain shapes and mechanical properties are obtained.
