Fig. 3From: Dysfunction of apoptosis and autophagy correlates with local recurrence in esophageal squamous cell carcinoma after definitive chemoradiationAutophagy in cells derived from primary and recurrent tumors. The numbers of autophagosomes per cell are shown. Data are presented as the mean ± SD. Subcellular structure analysis showed the typical morphological features of autophagy in cells from recurrent tumor samples, namely autophagic vacuoles containing cytoplasmic fragments or residual digested material. By contrast, only occasional autolysosomes were observed in cells from primary tumor samples (P < 0.05)Back to article page
