When dissociated blastula cells of the sea urchin Paracentrotus lividus were prevented from aggregating by extracting them with 2.5% n-butanol in sea water, they became unable to incorporate labelled thymidine, like over-diluted dissociated cells. If, however, cells were prevented from aggregating by the addition of Fab against plasma membranes, thymidine incorporation was not blocked, but increased compared to that of spontaneously aggregating cells. At the same time amino acid incorporation also increased.
当用海水中2.5%的正丁醇提取海胆紫球海胆的解离囊胚细胞以阻止它们聚集时，这些细胞变得无法掺入标记的胸腺嘧啶核苷，就像过度稀释的解离细胞一样。然而，如果通过添加抗质膜的Fab片段来阻止细胞聚集，胸腺嘧啶核苷的掺入并未受阻，反而与自发聚集的细胞相比有所增加。与此同时，氨基酸的掺入也增加了。
