23 Jul Modified acellular corneal stroma and modification method thereof
Abstract
The invention belongs to the field of tissue engineering, and particularly relates to modified acellular corneal stroma and a modification method thereof. The modification method comprises the following steps: (1) carrying out pretreatment on acellular corneal stroma; (2) reacting with the pretreated acellular corneal stroma by amino acid, and carrying out graft modification on the acellular corneal stroma; and (3) carrying out post treatment on the acellular corneal stroma subjected to graft modification, and removing the residual material in the graft modification process to obtain the modified acellular corneal stroma. The modified acellular corneal stroma has good mechanical property and biocompatibility, also has excellent rehydration water-retaining properties, can quickly restore the transparency after being implanted, and can be applied to tissue engineering research, clinical corneal transplantation and the like.
