Bulletin of Experimental Biology and Medicine Aims and scope

Summary

It has been shown that dividing cells are arranged in nests in the optic vesicle and the presumptive ectoderm in the period of contact between the two in a 48-hour-old chick embyro. The degree of this arrangement in the optic vesicle and ectoderm is variable: in the optic vesicle there are 29.4% of isolated mitoses and 25.9% of paired mitoses. The number of dividing cells per nest in the ocular rudiment is up to seven. In the ectoderm isolated mitoses account for 72.7%, paired ones −18.3%. The number of mitoses per nest does not exceed four. The number of isolated mitoses and various combinations of conjugate mitoses varies during a day.
