BM-MSCs were positive CD29 and negative for other markers, while PB-MSCs were positive for CD146, CD29, and CD140b and negative for Sca-1, CD44, CD45, CD90 and CD105. CD, cluster of differentiation; BM-MSCs, bone marrow-mesenchymal stromal cells; PB, peripheral blood; FITC, fluorescein isothiocyanate; PE, phycoerythrin.
