Effect of ritonavir on apoptosis and cell death in normal BM.
Samples of purified CD34+ cells, obtained from normal uninfected controls, were cultured with and without ritonavir and stained with annexin V or ICE antibody after 72 hours. (A) Summary of results from 5 experiments performed to measure the number of apoptotic cells. ▪ Indicates annexin; ▨, ICE. (B) Examples of flow cytometry scattergrams showing annexin-stained cells cultured with and without ritonavir.
