Figure 5

Cell morphology as shown by transmission electron microscopy (X24500) micrographs. Normal desmosome connections between cells (arrows) were seen at all temperatures, represented in (e) and (f). Large mitochondria (arrow) were more frequent at 24 °C (f). Mitochondrial fission or fusion (arrow) was also seen at 24 °C (inset (f)). Keratin bundles (arrowhead) were visible at all temperatures, but were more pronounced at 24 °C (f).
