Figure 4: Viability of primary normal bone marrow cells and normal CD34+ cells treated with algae extracts. Primary light density mononuclear cells (a) were treated with 8.0 μl/ml and 15 μl/ml doses of algae extracts for 24 hours and assayed for viability via annexin V staining. Normal CD34+ cells (b) isolated from healthy volunteers were isolated and cultured for 24 hours in the presence of algae extracts and stained for anexin V. Data shown is normalized to conditions with vehicle control ± standard errors of three independent experiments (*indicates ).
