Platelets are sensitive cells and are easily activated by different stimulants in the circulation system. It is known that tumor necrosis factor-alpha (TNF-α) is a proinflammatory cytokine and plays a role in inflammation. The role of TNF-α in the apoptotic process in blood platelets is unknown. In order to study the formation of apoptosis in platelets after incubation with TNF-α and/or ADP, several biomarkers were chosen: phosphatidylserine (PS) exposure and P-selectin binding; cGMP, Cyt-c, and Ca2+ levels and NOS activation; and gene and protein expression of caspase-3 and iNOS. Platelets were incubated with 100 pg/mL TNF-α and/or 50 mM iNOS …

The hematopoietic microenvironment regulates self-renewal and differentiation of hematopoietic stem cells. Mesenchymal stromal cells (MSCs) contribute to the niche and participate in supporting dendritic cell (DC) commitment in vitro and in vivo. However, due to MSCs being heterogenic, it is necessary to understand the function of the MSC subpopulation in modulating the DC commitment. The current study showed that one of the bone-related Sca1+ MSCs enhanced bone marrow cell differentiation into DCs by direct cell-to-cell contact. Furthermore, the expression of STAT3 and STAT5 genes decreased in supernatant cells after Sca1+ MSCs were cocultured with bone marrow cells. In contrast, the …
