Ni2＋ treatment causes cement gland formation in ectoderm explants of Xenopus laevis embryo

摘要

We found T-type calcium channel blocker Ni2+ can efficiently induce the formation of cement gland in Xenopus laevis animal cap explants.Nother T-typer specific calcium channel blocker Amiloride can also induce the formation of cement gland,while L-type specific calcium channel blocker Nifedipine as no inductive effect.These results may offer us an new approach to study the differentiation of cement gland through the change of intracelluar calcium concentration.
