✦ Synopsis


A variety of concentrations of the IMPase inhibitor L690,330 were added to sea urchin embryos. Immediate arrest of development was obtained for concentrations from 7.5 mm on. Concentrations lower than 3.5 mm permitted gastrulation but inhibited skeletogenesis and disturbed elongation along the animal-vegetal axis. The latter results are similar to those obtained by counteracting lithium effect with myoinositol, which are suggested to be due to partial relief of IMPase inhibition.

## Abstract The effect of a light stable retinoid (CD 367) was studied on sea urchin embryos. CD 367 did not affect sperm‐egg interaction. In a range of concentrations between 10 and 100 ΞΌM, CD 367 delayed the first and the second cleavages. When added after fertilization, micromolar amounts of CD
