Langerhans Cells And The Architecture Of The Epidermis In The Chick And Mouse, William Clyde Williams

Master's Theses

For more than a century, Langerhans cells have been known to occur in the mammalian epidermis. Experimental evidence has shown that their origin is ectodermal (Reams and Tompkins, 1973). Almost nothing ls known of their function. Mackenzie ( 1972) has shown a good correlation between the arrangement of epidermal Langerhans cells in the mouse and the ordered structure of the epidermis into columns. He has suggested that Langerhans cells might serve as an active organizer of epidermal structure.

As chickens do not have epidermal Langerhans cells, the present histological study was undertaken to compare the epidermal architecture of chick and …
