使用放射自显影技术，在大鼠肾上腺皮质中的增殖活性进行了检查，在胎龄20天，和标记的细胞的命运后48，168，336和672小时注射[3H]胸苷。在第20天的胎儿生活，标记的销售更多的小球比其他区域。每个细胞室中标记细胞的命运显示出向心迁移，但从妊娠第20天到产后5天，它们的位移，结合肾上腺大小的减少，表明了真实的迁移。向心性运动被发现在皮层时，增长已经有效地停止。
Using autoradiographic techniques, proliferative activity in the adrenal cortex of rats was examined on day 20 of fetal life, and the fate of labeled cells was followed 48, 168, 336 and 672 h after injection of [3H]thymidine. On day 20 of fetal life, labeled sells were more numerous in the zona glomerulosa than in the other zones. The fate of the labeled cells in each cell compartment showed centripetal migration, but their displacement from day 20 of pregnancy up to 5 days post-partum, combined with a reduction in the size of the adrenal gland, suggested a real migration. Centripetal movement was found in the cortex when growth had effectively ceased.
