[Studies on the differences between the skin of nude mice and bald skin in man]

The author carried out studies and established that in contrast to the bald skin of a man the elastic fibres in the skin of naked mice were completely normal and the small arteries and arterioles were with normal structure, because of which they could not be considered as a cause of degeneration of hair follicles, falling of hairs and of their irreplaceability with hairs grown externaly in these animals (fig. 4 a and b, fig. 5 a and b). The processes, occuring in the skin of the mice, are determined genetically and their manifestations represent changes in features, which, induced by mutation, are inherited.
