23 Jul Preparation and preservation method of amniotic membrane biological agent
Abstract
The invention provides a preparation and preservation method of an amniotic membrane biological agent. The method includes the first step of raw material selection and pretreatment, the second step of inactivation treatment of viruses, the third step of preparation, the fourth step of dyeing and the fifth step of preservation. Compared with the prior art, the method has following advantages that the preparation method is simple, raw materials are wide in source, large-scale industrial production can be achieved, prepared decellularized amniotic membranes are low in treatment strength and good in decellularization effect, and dense collagenous structures of natural amniotic membranes can be fully maintained. Amniotic membrane features are optimized easily, and important technical support can be provided for tissue engineering amniotic membrane industrialization.
