The young abnormality is distinguished early in its ontogeny by a group of undifferentiated, lightly staining cells which divide very rapidly. The rate of growth, however, decreases with increase in size and age. 4. The epidermis, which consists of a single layer of rather isodiametric cells, differentiates soon after the preceding stage. 5.
