Abstract

The invention discloses a preparation method for a three-dimensional cell scaffold based on collagen sponge-nanocellulose. The preparation method is characterized in that the preparation method for the three-dimensional cell scaffold based on the collagen sponge-nanocellulose is completed through the steps of preparation of collagen sponge, preparation of nanocellulose and preparation and cultivation of the collagen sponge-nanocellulose. The preparation method for the three-dimensional cell scaffold based on the collagen sponge-nanocellulose is reliable in result, easy and convenient to operate and high in repeatability, three-dimensional growth and proliferation of cells can be effectively promoted for a long time, meanwhile, a certain effect is achieved on formation of various human body three-dimensional micro-tissues, especially on formation of the liver cancer tissue function, and thus beneficial reference can be provided for the scientific research of liver tissue engineering and clinical treatment of liver cancers.

Description

technical field [0001] The invention belongs to the technical field of biomaterials and tissue engineering, and specifically relates to a [0002] Preparation method of collagen sponge-nanocellulose three-dimensional cell scaffold. Background technique [0003] Collagen is a structural protein that exists in the body in the form of collagen fibers. Collagen extracted from fresh porcine Achilles tendon, bovine Achilles tendon, etc. can maintain a triple helical structure, can re-form fibers under simulated physiological conditions, can obviously activate cell growth, and has good biological activity and tissue repair function. However, due to the poor mechanical strength and easy degradation, the application in medicine and tissue engineering is greatly limited. Therefore, it is especially important to improve the scaffold performance of collagen sponge to achieve wide application. [0004] TEMPO oxidized nanocellulose dispersion (TOCN) has the characteristics of large spec...
