DEVELOPMENTALEFFECTSOFLITHIUMCHLORIDEONXENOPUSEMBRYOS
PURPOSE: The objective of this experiment is to study the effect of lithium chloride treatment on early blastula xenopus embryos.INTRODUCTION: When the developing embryos of many organisms, such as the lytechinus variegatus (sea urchin) and xenopus (frog), are treated with lithium chloride, they experience alterations or perturbations in development. Lithium is believed to be the cause t......阅读全文
