Human Suprapatellar Fat Pad-Derived Mesenchymal Stem Cells Induce Chondrogenesis and Cartilage Repair in a Model of Severe Osteoarthritis

Figure 1

Supra- and infrapatellar fat pad cell populations in the SVF. The SVF derived from the mechanical and enzymatic homogenization of each fat pad of the knee were subjected to FACS analysis for immunodetection of mesenchymal superficial cell markers CD29, CD90, CD44, CD117, and CD105 as well as the hematopoietic cell marker CD34 and the mature leukocyte marker CD45. The positive cell populations were expressed as a percentage of the total analysed cell population. The mean ± SD of the identified population (in percentage) of twenty-four different samples was shown. in comparison with infrapatellar group.
