Flow cytometry results. Plt-MPs were isolated from platelet concentrate at the 7th day of storage. Daudi cells were treated with different concentrations of the isolated Plt-MPs for 5 days. After the co-culture time, the expression of CD86, CD27 and IgD was compared between the test (Daudi+ Plt-MPs 7th day) and control (Daudi) cells. The increasing profile for CD86, CD27 and decreasing profile for IgD were seen on the Daudi cells at the 3rd (a) and 5th (b) days of co-culture. Data were presented as the mean ± SD of five experiments. *Indicates the significant difference between the test and control (p < 0.05).
