Abstract: | Clonal cultures with 1,000–3,000 cells were prepared from cells harvested from high density cultures of neural retina of 8-day-old chick embryos. About 1.14% and 0.31% of inoculated cells developed into recogniziable colonies in Eagle's MEM and in Ham's F-12 supplemented with fetal calf serum respectively. Of these colonies, lentoid bodies of authentic lens nature were differentiated in 10% and 33.52% in MEM and F-12 respectively. Cells harvested from high density cultures of the anterior and posterior portions of the neural retina were clonally cultured. Plating efficiency was much higher in the anterior cells than in the posterior ones and clonies with lentoid differentiation were developed only in clonal cultures of the anterior cells. |
