Permeable embryonic cells of sea urchins as a model for studying nucleus-cytoplasm interactions

  • Published:
Experientia Aims and scope Submit manuscript

Summary

Sea urchin embryonic cells were made permeable by treating them with glycerol solution for the purpose of exchanging cytoplasmic components. When proteoglycans prepared from embryos of advanced stages of development permeated into these glycerinated cells, these substances accumulated rapidly in the nucleus, being bound with chromatin.
