Summary:Results of studying spinal marrow histogenesis in age varying Japanese quail embryos and chicklings whose embryonic development took place in microgravity are presented. Histological comparison of spinal cords showed retardation of morphogenetic development, lumber spine especially, in the group of flight embryos manifested as incomplete proliferative activity during migration processes and nervous cell differentiation. Like on earth, in space microgravity chicklings also hatched on day 17 of embryogenesis. Multiform marrow changes in space chicklings were a nervous cells reaction to the functional state of organism in the micro-g environment.
