[钙在沙蠋（Sabellaria alveolata (L.)，环节动物门，多毛纲）卵母细胞减数分裂重新启动中的作用]

C R Acad Hebd Seances Acad Sci D. 1977 Oct 10;285(8):913-5.

Meiotic maturation is triggered by ionophores A 23187 and X 537 A, even in absence of extracellular calcium. CaMg free medium alone initiates 100% maturations while Ca free SW triggers varying percentages of maturation and Mg free SW has no effect.

减数分裂成熟可由离子载体A 23187和X 537 A触发，即使在没有细胞外钙的情况下也是如此。仅无钙镁培养基就能引发100%的成熟，而无钙海水能引发不同百分比的成熟，无镁海水则没有影响。
