Abstract (original English)
White adipose tissue is a source of mesenchymal stromal/stem cells (MSCs) that are actively studied for their possible therapeutic use in bone tissue repair/remodeling. To better appreciate the osteogenic potential of these cells, we compared some properties of MSCs from human subcutaneous adipose tissue [subcutaneous-adipose stromal cells (S-ASCs)] and dental pulp stem cell (DPSCs) of third-impacted molars, the latter representing a well-established MSC source. Both undifferentiated cell types showed similar fibroblast-like morphology and mesenchymal marker expression. However, undifferentiated S-ASCs displayed a faster doubling time coupled to greater proliferation and colony-forming ability than DPSCs. Also, the osteogenic differentiation of S-ASCs was greater than that of DPSCs, as evaluated by the higher levels of expression of early osteogenic markers Runt-related transcription factor-2 (RUNX2) and alkaline phosphatase at days 3-14 and of extracellular matrix mineralization at days 14-21. Moreover, S-ASCs showed a better colonization of the titanium scaffold. In addition, we investigated whether S-ASC osteogenic commitment was enhanced by adenosine A1 receptor (A1R) stimulation, as previously shown for DPSCs. Although A1R expression was constant during DPSC differentiation, it increased in S-ASC at day 21 from osteogenesis induction. Accordingly, A1R stimulation by the ag
