Collagen hydrogels useful as cell carriers

Abstract

A collagen hydrogel which has a 3D fibrillar structure with micropores obtainable by a process including: providing an acidic mass of native Type I collagen fibers dispersed in water in a concentration comprised between 1-15% in weight; b) neutralizing the acidic mass to adjust the pH to physiological pH; and c) applying beta radiation in a range of up to 50 KGy; wherein the acidic mass has a pH between 0.5-5; and fibers, wherein the acidic mass includes fibers, wherein at least 90% of the total mass of the fibers have a length in of 1 μm to 2500 μm and a fiber diameter of from 0.1 to 150 μm measured at a pH between 1 and 2. A process for its preparation as well as its use as support for cell tissue or as scaffold of cultured meat, as well as the hydrogel for use in biomedical applications.
