FIG. 4. Ultrastructure of the wound epithelium (EP). The cytoplasmic content is different in the outermost cells rich in cytokeratin tonofilaments (arrow) as compared with the cells located below (star). There, in addition to intermediate filaments, mitochondria and free ribosomes are quite prominent, suggesting high synthetic activity. Note the changes in size and electron density of the nucleus from the basal region toward the surface of the epithelium where c-myc transcription is no longer observed (MB, mesenchymal cells). (x 7360).
