Abstract
Langerhans' cells were observed to migrate into chemically injured corneal epithelium of pigmented and albino guinea pigs in substantial numbers. Whereas the migration of Langerhans' cells was a regular occurrence in both pigmented and nonpigmented animals, the migration of melanocytes occurred in only a portion of the pigmented animals and in fewer numbers. These observations may have significance in relation to the possible origin and function of the Langerhans cell.
