Abstract (original English)
Adipose-derived and bone marrow stem/stromal cells (ASCs and BMSCs) have been often compared for their application in regenerative medicine, and several factors sustaining their differentiation and efficacy have been investigated. 17 β-estradiol (E2) has been reported to influence some functions of progenitor cells. Here we studied the effects of 10 and 100nM E2 on ASC and BMSC vitality, proliferation and differentiation towards osteogenic and adipogenic lineages. E2 did not modulate ASC and BMSC vitality and growth rate, while the hormone produced a pro-adipogenic effect on both mesenchymal stem/stromal cells (MSCs). In particular, the synergy between 7-day pre-treatment and 100nM E2 led to the most evident result, increasing lipid vacuoles formation in ASCs and BMSCs of +44% and +82%, respectively. Despite the fact that E2 did not alter collagen deposition of osteo-induced MSCs, we observed a different modulation of ASC and BMSC alkaline phosphatase (ALP) activity. Indeed, this osteogenic marker was always enhanced by 17 β-estradiol in BMSCs, and 7-day pre-treatment with 100nM E2 increased it of about 70%. In contrast, E2 weakened ASC osteogenic potential, reducing their ALP activity of about 20%, with the most evident effect on ASCs isolated from pre-menopausal women (-30%). Finally, we identified an estrogen receptor α (ERα) variant of about 37kDa expressed in both MSCs. In
