Figure 2: [A-H]: Monitoring of morphological changes in MCF-7 cells post treatment with C.ceratstes and V.lebetina venoms relatively to concentrations 24 h post treatment [A and E]: Untreated cell control; [B]: cells treated with C.cerastes (0.75 μg/ml); [C]: cells treated with C.cerastes (1.5 μg/ml); [D]: cells treated with C.cerastes (3 μg/ml); [E]: cells treated with V.lebetina (1.25 μg/ml); [F]: cells treated with V.lebetina (2.5 μg /ml); [G]: cells treated with V.lebetina (5 μg /ml) showing distinct cytotoxic effect of test venoms with larger areas of detached cells along with increasing venom concentrations compared to the normal appearance of untreated MCF-7 cells.
