[Analysis of the formation of tissue antigens of the retina of chicks in embryogenesis].

The following antigens were found in the chick retina: one organospecific, three interorganic antigens of narrow specificity characteristic of only the tissues of the eye and brain, and seven interorganic antigens of broad specificity characteristic of, besides the tissues of the eye and brain, many other organs of the chick. The interorganic antigens of broad specificity manifest themselves the first in the retina during development. The interorganic antigens of narrow specificity and the organospecific antigen arise during the period of retinal histogenesis. One of the antigens of narrow specificity (retina--iris--brain) arises in the brain at the same time as in the retina.
