Sixteen years ago, an area on the forearm of a freckled subject was painted with a solution containing 500 esu of thorium‐X per ml. Since then, despite much exposure to solar irradiation, there has been a complete absence of freckles from this area, which stands out in marked contrast to the surrounding skin. Biopsy of the skin from the area was examined by the Dopa technique and by electron microscopy. Melanocytes are present in apparently normal numbers, but in a condition of almost complete… Expand

TLDR
Freckled skin should provide very suitable material for a study of the histochemical reactions with various substrates of melanocytes of different morphology and population densities, and for a comparison of any resulting melanogenic activity with the amount of naturally occurring melanin. Expand

ELECTRON MICROSCOPY OF MELANOCYTES AND MELANOSOMES IN FRECKLED HUMAN EPIDERMIS.
TLDR
The suggestion that in epidermis of freckled individuals there may be two types of melanocyte with inherently different capacities for melanogenesis, each of which is a member of a distinct and “true-breeding” somatic cell lineage is suggested. Expand
Melanocyte Counts on Human Forearm Skin1
TLDR
In the course of a present investigation into a possible correlation between melanocyte concentration and differences in skin color in white (Caucasian) subjects, counts were carried out on corresponding areas of forearm skin of ten individuals, which comprise a larger series than has been hitherto available for this region.

Melanocytes in Early Regenerated Human Epidermis
TLDR
Two cellular components, each of different developmental origin, are present in fully differentiated normal human epidermis and it is generally agreed that the system of pigment-forming cells, or melanocytes is derived developmentally from the neural crest. Expand
