The Effects Of Ultraviolet Irradiation On The Pigment Cells Of The Pet/Wmr Mouse Epidermis, Vaughan Henry Howard Jr.
Master's Theses
Epidermal melanocytes in mammals are known to occur in a variety of shapes, sizes, and colors. The basic melanocyte morphology is dependent upon genetics, but there are a number of environmental factors that can cause modification.
In the epidermis of PET/\vrnr mice, the population of rnelanocytes reaches a peak and begins to decline during the first post-natal week, and has disappeared within four weeks. Dispersed among the large, highly DOPA-reactive melanocytes are miniature melanocytes. These miniature melanocytes are weakly DOPA-reactive and appear early in the post-natal period. The miniature melanocyte population is relatively constant and these miniature cells are among …

The Induced Differentiation Of Mouse Ectoderm To Epidermis By Growth On Freeze-Thawed Dermis, Albert Joseph Banes
Master's Theses
Previous investigators have grown or maintained adult or embryonic skin in tissue culture and on the chorioallantoic membrane (CAM) of chickens. These studies have revealed two important factors involved in culturing skin: (1) the presence of an inducer which originates in the dermis and affects the phenotype of epithelial cells; and (2) the influence of the physical surface of the substrate on which epidermis is cultured.
The current investigation presents evidence that ectoderm from the limb buds of 10 to 12 day-old mouse embryos can form an epidermis when combined with dermis killed by alternate freezing and thawing, and cultured …
