Figure 5. Exemplar TEM images of HCC70 cells cultured in hydrogel.

HCC70 cells grew adjacent to each other in hydrogel and comprised several mitochondria (A–D,‘m’), autophagic vacuoles (A, C,‘av’) and intercellular junctions (A, B,‘*’). The data are representative of two independent experiments (A, B: Experiment 1; C, D: Experiment 2). Scale bar = 500 nm.
