Method for reshaping and beautifying by using tissue engineering fat regeneration technology

Abstract

The invention provides a method for reshaping and beautifying by using tissue engineering fat regeneration technology, which is applicable to plastic surgery and reshaping and beautifying and belongs to the field of tissue engineering. The method comprises the following technical routes: directly extracting mesenchyme matrix cells with multiple differentiation capabilities from fatty tissues of a patient, culturing and propagating the mesenchyme matrix cells in vitro, wrapping a specific amount of cells and other necessary components in a hydrogel stent material, and implanting the hydrogel stent material into the corresponding part in the body of the patient. The cells are grown into fatty tissues along with degradation and absorption of the stent material so as to perform regenerative repair on the soft tissue defect of the patient. The method has the advantages that the cells of the patient do not bring immunological rejection to the patient, and the regenerative repair effect is safe, natural and durable because the used hydrogel stent material is finally degraded and absorbed in the body of the patient.

Description

technical field [0001] The invention provides a method for repairing human body defect tissue by using human body's own stem cells, which is suitable for plastic surgery and cosmetic surgery, and belongs to the field of tissue engineering. Background technique [0002] The loss of tissues and organs is one of the major hazards to human health and the leading cause of human disease and death. Currently, there are roughly three ways to repair tissues or organs commonly used clinically: autologous tissue transplantation, allogeneic tissue transplantation, or the use of tissue substitutes. Although there is no immune rejection in autologous tissue transplantation, the sources are limited and cause damage to the donor site. Allogeneic tissue transplantation can cause acute rejection and disease infection, and there are also defects such as limited supply; although artificial tissue substitutes have been widely used in recent years, they do not have physiological activity, do not...

Problems solved by technology

Allogeneic tissue transplantation can cause acute rejection and disease infection, and there are also defects such as limited supply; although artificial tissue substitutes have been widely used in recent years, they do not have physiological activity, do not belong to a physiological repair, and are prone to infection , so its application is still limited
