Procedure and device for separating adult stem cells from fatty tissue
The invention relates to a method for separating adult stem cells from fatty tissue, wherein the fatty tissue is mixed with a fluid and the stem cells are subsequently separated. The fatty tissue with fat cells and adult stem cells is exposed to a fluid jet ( 38 ) having a pressure adjusted such that the adult stem cells are separated from the fat cells and the adult stem cells are separated from the fat cell-stem cell-fluid mixture. A container ( 12 ) is provided for receiving fatty tissue removed from a biological structure, which includes fat cells ( 62 ) and adult stem cells ( 64 ), wherein the container ( 12 ) has a feed device ( 28 ) for a pressurized fluid and the feed device ( 28 ) includes an outlet the arrangement ( 30 ) for the fluid which is introduced or can be introduced into the fatty tissue.
1. Apparatus for separating adult stem cells from fatty tissue, comprising a container ( 12 ) for receiving fatty tissue removed from a biological structure, the fatty tissue comprising fat cells ( 62 ) and adult stem cells ( 64 ), wherein the container ( 12 ) has a feed device ( 28 ) for a pressurized fluid and the feed device ( 28 ) comprises an outlet arrangement ( 30 ) for the pressurized fluid, wherein the outlet arrangement ( 30 ) is introduced or is structured for introduction into the fatty tissue, the pressure of a fluid of the pressurized fluid jet being adjustable such that the adult stem cells may be separated from the fat cells and the adult stem cells may be separated from the fat cell-stem cell-fluid mixture.
2. Apparatus according to claim 1 , wherein the outlet arrangement ( 30 ) comprises a hollow body with an inlet opening ( 34 ) and an outlet opening ( 36 ), wherein the fluid jet ( 38 ) passes through the outlet arrangement ( 30 ).
3. Apparatus according to claim 2 , wherein the hollow body is constructed as a hollow cylinder ( 50 ).
4. Apparatus according to claim 3 , wherein the hollow cylinder ( 50 ) comprises flow surfaces ( 58 ).
5. Apparatus according to claim 1 , wherein the outlet arrangement ( 30 ) comprise a Venturi nozzle.
