Abstract

The study of adhesive properties of multipotent mesenchymal stromal cells evaluated from fibroblast colony-forming units in the bone marrow of adult mice and rats in populations of cells attached and unattached to plastic substrate after 2 h to 7 days in culture demonstrated both similarities and differences. The increase in the fibroblast colony-forming units in the adhesive population peaked on day 7 of in vitro culture in both cases; however, nearly no fibroblast colony-forming units were observed in the nonadhesive population from the mouse bone marrow in this period. Conversely, the number of colonies from the rat bone marrow nonadhesive population on day 7 of culture considerably increased, and this nonadhesive population in long-term culture became the source for subsequent nonadhesive subpopulations containing fibroblast colony-forming units. After 7 days of in vitro culture, the suspension of cells isolated from the liver of 17-day-old rat fetuses also contained a fraction of unattached fibroblast colony-forming units. In the nonadhesive subpopulations from the bone marrow and fetal liver, fibroblast colony-forming units were observed up to day 48 and 30, respectively. Stromal cell precursors of nonadhesive subpopulations from the rat bone marrow featured a period of colony formation reduced to 7 days (i.e., they were formed 1.5-2 times faster compared to the primary culture). The total number of fibroblast colony-forming units from all nonadhesive subpopulations was roughly 6 and 7.4 times that of the adhesive population of the primary culture from the bone marrow and fetal liver, respectively. Considering that the mammalian bone marrow remains the preferred source of mesenchymal stromal cells, using nonadhesive subpopulations in the presented culture system can considerably increase the yield of stromal precursor cells
