Figure 4From: Low-dose etoposide-treatment induces endoreplication and cell death accompanied by cytoskeletal alterations in A549 cells: Does the response involve senescence? The possible role of vimentin DNA fragmentation rate in A549 cells after treatment with etoposide - representative histograms from flow cytometric analyses (the TUNEL method); upper left - control cells, upper right - 0.75 μM etoposide, lower left - 1.5 μM etoposide, lower right - 3 μM etoposide.
