摘要
Abstract
Timing of vegetal-endodermal cell determination in amphioxus embryos remains uncertain. We tentatively tested effects of A23187
the calcium ionophore
on the development of vegetal blastomeres isolated at the 16-cell stage. It was found that when vegetal blastomeres committed to endoderm were treated with A23187 prior to gastrulation
they were transformed into ectodermal cells as evidenced by the cell morphology and function characteristic of epidermis. However
the developmental fate of the same blastomeres untreated or treated with DMSO at the same stage or of those treated with A23187 after gastrulation remained unchanged. Thus
vegetal-endodermal cells in amphioxus embryos are not irreversibly determined before the gastrula stage
and artificial increase in intracelluar Ca2+ concentration can induce transdetermination of the predetermined endodermal cells into ectodermal cells.
