ADIPOSE STROMAL VASCULAR FRACTION-CONDITIONED MEDIUM
A combination of therapeutic factors derived from non-adherent or poorly adherent stromal vascular fraction (SVF) cells exposed to protein-free basal medium are disclosed.
1 . A conditioned medium obtained from digested adipose tissue.
2 . The conditioned medium of claim 1 , wherein the digested adipose tissue is a fractioned adipose tissue.
3 . The conditioned medium of claim 2 , wherein the fractioned adipose tissue is selected from the group consisting of adipose-derived stem cells and non-adipocyte, stromal-vascular fraction.
4 . A conditioned medium obtained from a non-adipocyte, stromal-vascular fraction.
5 . The conditioned medium of claim 4 , wherein the conditioned medium is obtained from a suspension culture of the non-adipocyte, stromal-vascular fraction.
6 . The conditioned medium of claim 4 , wherein the non-adipocyte, stromal-vascular fraction comprises at least one of a leukocyte and an endothelial cell.
7 . A method of producing conditioned medium, the method comprising: digesting adipose tissue by contacting the adipose tissue with an enzyme; fractionating the adipose tissue to obtain a fractionated adipose tissue that comprises at least a stromal-vascular fraction; culturing cells obtained from the fractionated tissue in a culture medium; and separating the cells from the culture medium to produce the conditioned medium.
8 . The method of claim 7 , cells obtained from the stromal-vascular fraction are cultured in the culturing step.
9 . The method of claim 8 , wherein the stromal-vascular fraction is selected from the group consisting of a freshly isolated population of stromal-vascular fraction and a non-adherent population of stromal-vascular fraction.
10 . The method of claim 7 , further comprising culturing cells from digested adipose tissue after the digesting step for a sufficient time to allow a plurality of cells to adhere to a culture substrate; collecting non-adherent cells; culturing the non-adherent cells; and collecting culture medium after the culturing of the non-adherent cells, wherein the culture medium results in the conditioned medium.
11 . The method of claim 10 , wherein the culture substrate comprises a plastic culture dish.
12 . The method of claim 11 , wherein the plastic culture dish is an uncoated plastic culture dish.
13 . The method of claim 10 , wherein the culturing the non-adherent cells comprises a suspension culture.
14 . The method of claim 13 , wherein the conditioned medium is obtained from a non-adipocyte, stromal-vascular fraction of the adipose tissue.
