Abstract (original English)
Mesenchymal stem cells (MSC) are multipotent progenitors retaining the capability to undergo multilineage differentiation, mostly towards all the mesodermal cellular lineages. MSC growing under standard conditions are composed of two main subpopulations with a characteristic distribution in the morphologic flow cytometric scatter: RS (recycling stem) cells (small, agranular) and m (mature) MSC (large, moderately granular cells). MSC obtained from BM of healthy donors and expanded in culture were characterized by evaluating both the expression of conventional markers and differentiation potential. We used CFSE, a lipophilic dye that is taken up by cell membranes, to investigate separately the proliferative activity of RS cells and mMSC subsets. With flow cytometric analysis, RS cells and mMSC showed nearly the same immunophenotypic pattern, even if a significantly smaller percentage of RS cells expressed some of the classic mesenchymal Ag. The RS cell fraction was confirmed to have a higher proliferative potential and such a feature was particularly evident under certain culture conditions. CFSE has been shown as a reliable method for studying the proliferative activity of MSC subpopulations identified by flow cytometric analysis. The acquisition parameter strategy is crucial for the accuracy of the analysis.
