Problems solved by technology

Mature adipocytes can only increase the volume of the transplanted site and mature adipocytes are vulnerable to external mechanical damage, so that a considerable number of mature adipocytes are damaged and destroyed

Embodiment Construction

[0015] This method of enhancing fat survival and regeneration of adipose tissue involves the following steps:

[0016] a. Extraction of preadipocytes

[0017] Extract the postoperative adipose tissue mixture from human adipose tissue under sterile conditions and put anesthetics in the washing solution (d-hank's washing solution, which is prepared from sodium chloride, disodium bicarbonate and potassium chloride, etc.) After the blood cells were washed, they were left to stand for 40 minutes in sterile saline at 2-5°C; then, the centrifuge was set at 1500 rpm again, and after ten minutes of centrifugation, the supernatant was discarded to obtain preadipocytes.

[0018] Preadipocytes are isolated from the adipose tissue mixture after extraction from human adipose tissue. The adipose tissue has the advantages of convenient sampling and high content of stem cells. According to the average experimental data, 2X108~6X108 adipose mesenchyme can be obtained per 30ml of adipose tissue....

Abstract

The invention discloses a method for improving fat survival rate and regeneration of adipose tissue, which includes extracting pre-adipocytes, transplanting fat cells, extracting nutrient components and backfilling and transplanting. The fat cells obtained by the method of the present invention can continuously differentiate into fat cells after transplantation, which solves the problems of traditional fat transplantation absorption activity and fat cell transplantation absorption or necrosis; the transplanted fat can survive in a long-term, lasting and stable manner. The material extracted by the present invention is transformed into fat cells after transplantation, which can promote the continuous growth of the original fat cells, and eventually become stable fat tissue, with a survival rate as high as 90%. Activated adipocytes transform into adipocytes, form adipose tissue at the site to be filled, promote the continued growth of original adipocytes, help form blood vessels, accelerate vascularization and resurvival of grafted fat, and release factors that promote angiogenesis, which can The rapid survival of transplanted fat into normal and viable adipose tissue can significantly improve the patient's physical beauty.

Description

technical field [0001] The invention relates to a method for the survival and regeneration of fat cell autologous transplantation. Background technique [0002] Since Neuber first reported the success of free fat transplantation in 1893, many medical and aesthetic experts have used this method to perform a large number of filling repairs on breasts, faces and other parts, but none of them have achieved the expected surgical results. Fat is mainly distributed in human subcutaneous tissue, omentum, mesentery and perirenal and other parts. Adipose tissue is composed of preadipocytes and mature adipocytes. The patina in mature adipocytes contains 90% lipid droplets, which can be quickly metabolized after transplantation. Mature adipocytes are terminally differentiated cells that have lost the ability to continue proliferating. Mature adipocytes can only increase the volume of the transplanted site and mature adipocytes are vulnerable to external mechanical damage, so that a co...
