Abstract (original English)

Objectives The use of infrapatellar fat pad adipose stem cells (IPFP-ASCs) shows an age-independent proliferation and differentiation potential. In addition, the pronounced chondrogenic potential of IPFP-ASCs makes them promising candidates for research for use in other methods of regenerative therapy. The purpose of this study was to ascertain the presence and compare the relative abundance of cells exhibiting an immunohistochemical profile characteristic of adipose-derived mesenchymal stem cells in selected samples of the stromal vascular fraction (SVF) obtained from the IPFP and subcutaneous fat tissue. Methods A direct immunohistochemical study was carried out in serial paraffin sections of the SVF of the infrapatellar fat pad (IPFP) and subcutaneous tissue, using monoclonal antibodies. The minimum criteria were established by the International Society for Cell Therapy to ensure the identity of mesenchymal stem cells use CD73, CD90, and CD105 as positive markers and CD34, CD31, and CD45 as a negative. Results According to the results of histological, immunohistochemical, morphometric, and statistical studies, it was found that in the SVF of IPFP and subcutaneous adipose tissue, the relative number of cells with the profile CD105+, CD73+, CD34+, CD31-, CD45- in the standard field of view (×200), the SVF of IPFP was 1.58%, whereas the SVF of subcutaneous adipose tissue was 6.
