The coelomic envelope of Xenopus laevis eggs: a quick-freeze, deep-etch analysis.

abstract：:To investigate the mechanism by which the hormone 17 alpha,20 beta-dihydroxy-4-pregnen-3-one(17 alpha,20 beta-DP) acts on a receptor on the external surface of rainbow trout oocytes to induce maturation, the interaction between 17 alpha,20 beta-DP receptors and G-proteins was examined.
