[Characteristics of human mesenchymal stem cells isolated from bone marrow and adipose tissue].

Populations of human mesenchymal stem cells were derived from bone marrow and adipose tissue. Here analysis of six individuals is represented. Cells were isolated, expanded and evaluated by the expression of surface antigens using flow cytometry. These cells displayed similar characteristics for many markers. Cells isolated from bone marrow and adipose tissue were found to be homogeneously positive for CD13, CD44, CD90, CD105, and negative for CD45, CD34, CD31 and CD117. Besides, differences in surface antigene CD10 expression between narrow and adipose tissue-derived cells were detected. All these findings indicate that both bone marrow and adipose tissue are important sources of mesenchymal stem cells, which could be used in cell therapy protocols.
