  • Title: [Radioautographic study of cell proliferation in the pigment epithelium of tritons after transplantation into the cavity of a lens-free eye].
    Author: Mitashov VI, Grigorian EN.
    Journal: Ontogenez; 1984; 15(1):49-54. PubMed ID: 6700938.
    Abstract:
    The proliferative activity of the pigment epithelium cells transplanted in the lens-less eyes was studied in the adult crested newt. The cells of transplanted pigment epithelium incorporated 3H-thymidine injected intraperitoneally. Within 10 days after explantation, the index of labelled nuclei equaled 27.8-34.0% and within 20 days the number of labelled cells doubled. By that time the proliferating transplant cells were depigmented and formed 2-3 rows of cells of retinal rudiment. In response to the removal of lens from the of recipients eyes their regeneration proceeded. Irrespective of participation (dorsal iris) or nonparticipation in lens regeneration (ventral iris), the index of labelled nuclei in these regions of iris had similar values. The eyes of recipients were also characterized by a local proliferation of pigment epithelium cells in the zones of retinal detachment. In these zones the index of labelled nuclei in the pigment epithelium equaled 11.0-31.3%.
