23 Jul Method for pre-vascularization of biological structure body
Abstract
The invention discloses a method for pre-vascularization of a biological structure body. The method specifically comprises the steps that a hydrogel I film is prepared, a solid channel is printed, hydrogel III is prepared, a sandwich body is prepared, and a scaffold is prepared. The hydrogel with biocompatibility and biodegradability serves as a main body material of the scaffold, forming of the scaffold and opening of internal micro-channels of the scaffold are achieved through cross-linking forming characteristics between ions, the process is simple, preparation conditions are mild, a complex vascular network channel can be formed, and the material in use has good biocompatibility and can be well applied to the field of tissue engineering.
