Apoptosis induction in NCI-H929 cell lines. Annexin V/PI assay of NCI-H929 cells incubated with 0.5, 1, 2, 4 × IC50 of chloroform fractions of (A)-T. vulgaris (TCF) and (B)-A. lappa (ACF) for 48 and 72 h. Morphology of NCI-H929 cell was noticed under fluorescence microscope by using 4′,6-diamidino-2-phenylindole (DAPI) stain. Yellow arrows referred to apoptotic features were observed in A-TCF and B-ACF treated cells vs. untreated cells. Control: NCI-H929 cell without treatment.
