TCE induces apoptosis and cell cycle arrest.

<p>(<b>A</b>) Distribution of viable, early apoptotic, late apoptotic and necrotic cells analysed by extent of expression of annexin V on the surface of cells and total PI uptake by flow cytometer. (<b>B</b>) Histogram showing percentage of cells in viable, early apoptotic, late apoptotic and necrotic stages. (<b>C</b>) Histogram representing distribution of cells in G0/G1, S and G2/M phase of cell cycle analysed by PI stain using flow cytometer. ‘*’ represents statistical significant difference (<i>p</i><0.05) between control and TCE treated group.
