Antitumor Activity of Ethanolic Extract of Dendrobium formosum in T-Cell Lymphoma: An In Vitro and In Vivo Study

Figure 3

Acridine orange/ethidium bromide staining was carried out to reveal apoptotic cell morphology of DL treated cells with the ethanolic extract at 50, 100, 150, 200, and 250 μg/mL and a control on 3 h, 6 h, 16 h, and 20 h incubation, respectively [blue arrow shows live cells, red arrows show late apoptotic cells, dotted red arrow shows membrane blebbing in early apoptotic cells, and yellow arrows show necrotic cells].
