Title:
DEVICE FOR ISOLATING CELL FRACTIONS FROM HUMAN AND ANIMAL TISSUES AND METHOD FOR THE USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/078563
Kind Code:
A8
Abstract:
The present invention relates to medical biotechnology and cell technology. Proposed is a method for isolating stromal vascular fraction of adipose tissue, which includes: decantation of a lipoaspirate; delicate washing of the lipoaspirate in buffer solutions; enzymatic treatment using a mixture of collagenases, thermolysin, dispase and trypsin at a temperature of 37ºC; centrifugation at 500-2000 g and filtration through microfilters with a pore size of 10-300 microns with the subsequent removal of fat and stromal tissue matter; repeat washing, and concentration of the cell fraction, wherein all of the stages of the process are carried out under closed system conditions. A corresponding device is configured as a sealed container consisting of two chambers, which are separated from one another by nylon microfilters with pore sizes of 10-500 microns. The device comprises fittings, provided with valves, and channels for the introduction and removal of biological tissue and a cellular end product for subsequent administration. Owing to the presence of a cocktail of mature and progenitor cells in stromal vascular fraction, which have a paracrine effect, the sterility of all of the stages of the process and the safety thereof, the claimed method can be used in medicine for the cell-based therapy and regeneration of organs and tissues, including: soft tissue and bone regeneration, and the treatment of cosmetic defects, chronic trophic and radiation ulcers, burns, Crohn's disease, multiple sclerosis, graft-versus-host reactions, myocardial infarction and strokes of different origins.
