[Lens cell growth in tissue culture]

The epitheliomorphous zones of growth of piece explants of the mammalian embryonic lenses are comparable with those of neuroectodermal origin in formation of the rosette-shaped, perle-like and neuroretinal structures. They differ from the epidermal epithelia by absence of keratinization. The cambial and differentiated cells of the lens in the culture retained their specificity and differentiated. Comparison of the personal and literature data confirms N. G. Chlopin's idea of a necessary inclusion of the lens tissue in the group of tissues of the ependimo-glial type.
