Abstract
Provided are uses of allogeneic interstitial vessel-layer cells and allogeneic mesenchymal progenitor cells in the preparation of a pharmaceutical composition for preventing or treating osteoarthritis (OA). Also provided is a pharmaceutical composition containing the allogeneic interstitial vessel-layer cells and the allogeneic mesenchymal progenitor cells.
Claims12
A method for preparing a pharmaceutical composition for preventing and/or treating osteoarthritis, comprising:
- mixing allogeneic interstitial vessel-layer cells (SVF) and allogeneic mesenchymal progenitor cells (haMPCs) with a pharmaceutically acceptable carrier,
- wherein the allogeneic mesenchymal progenitor cells have one or more features selected from the group consisting of
- (i) more than 95% of the cells having surface antigen CD90,
- (ii) more than 95% of the cells having surface antigen CD73,
- (iii) more than 95% of the cells having surface antigen CD29, and
- (iv) more than 95% of the cells having surface antigen CD49d,
- wherein the allogeneic interstitial vessel-layer cells have one or more features selected from the group consisting of
- (a) more than 30% of the cells having surface antigen CD29,
- (b) more than 50% of the cells having surface antigen CD73,
- (c) more than 85% of the cells having surface antigen CD49d, and
- (d) more than 55% of the cells having surface antigen CD90,
- wherein the haMPCs are prepared by a method including:
- digesting an adipose tissue by an enzyme to obtain stromal vascular fraction cells;
- inoculating the stromal vascular fraction cells into a culture flask to obtain adherent cells;
- culturing the adherent cells for 5-7 days to obtain primary adherent cells;
- and
- subjecting the primary adherent cells to passage at a ratio of 1:1-2 and culturing for 2-3 weeks.

- (iv) more than 95% of the cells having surface antigen CD49d;
- (v) less than 2% of the cells having surface antigen HLA-DR;
- (vi) less than 2% of the cells having surface antigen Actin;
- (vii) less than 2% of the cells having surface antigen CD34;
- (viii) less than 2% of the cells having surface antigen CD45;
- and
- (ix) less than 2% of the cells having surface antigen CD14
- wherein the allogeneic interstitial vessel-layer cells have:
- (a) more than 30% of the cells having surface antigen CD29;
- (b) more than 50% of the cells having surface antigen CD73;
- (c) more than 85% of the cells having surface antigen CD49d;
- (d) more than 55% of the cells having surface antigen CD90
- (e) less than 85% of the cells having surface antigen CD34;
