[An analysis of the distribution of clone cells in the retinal pigment epithelium from chimeric mice].

The quantity of pigmented and unpigmented cells was estimated in the retinal pigment epithelium (RPE) in ten newborn and five 20-days old aggregated chimaeric mice C/C----c/c. A strong correlation was shown in the proportion of cells of the paternal genotypes either in the whole RPE of right and left eyes or in its separate regions, i.e. dorsal, central, ventral. Random distribution was revealed in these RPE cells clones. A high correlation was shown between the number of RPE pigmented cells and percentage of coat pigmentation.
