Abstract (original English)
Mesenchymal stromal cells (MSCs) from umbilical cord blood (CB) attract attention by significantly impaired or absent adipogenic differentiation compared with MSCs derived from bone marrow (BM) and adipose tissue (AT). The diverging adipogenic propensity between the developmentally younger CB-MSCs and MSCs of the adult AT and BM resembles the age-dependent process in the BM, where adipose tissue increases with advancing age, accompanied by loss of bone stability. Thus, MSCs appeal as an attractive model to study the adipogenic process with respect to tissue sources and developmental ages. We followed the expression of main adipogenic transcription factors, genes and protein markers in CB-, BM- and AT-MSCs under adipogenic induction, after silencing of preadipocyte factor 1 (Pref-1, PREF1) and after incubation with CB-plasma supplemented adipogenic media. An inverse relation in the expression of adipogenesis-associated markers and PREF1 in CB-MSCs suggested an inhibitory role of Pref-1 toward adipogenesis. However, Pref-1 protein was rarely detected in CB-MSCs, and siRNA silencing of Pref-1 failed to induce adipogenic differentiation in CB-MSCs. Thus, the impaired adipogenic differentiation of CB-MSCs in vitro was unrelated to endogenous Pref-1 protein expression. Nevertheless CB-plasma containing Pref-1 protein revealed an anti-adipogenic effect on AT-MSCs. Because Pref-1 is va
