Suppression of TPO protein expression in human BM stromal cells by PF4 and TSP.
The addition of PF4 and TSP to stromal cells in culture suppressed TPO protein expression, as measured by an enzyme-linked immunosorbent assay. The results shown are the mean ± SD values from 3 separate experiments carried out in triplicate. *P < .05 compared with controls.
