Abstract

Metaphase spread preparation in adult abalone has not been successful, which has restricted the applications of karyotyping-based technologies. Here, we present a non-lethal method to enable preparation of metaphase spreads from live adult abalone using a tissue culture method. Mantle tissue fragments from live adult abalone were cultured in vitro and the cultured cells were used for metaphase spread preparation. To retrieve a sufficient number of proliferating cells required for metaphase spread preparation, at least 14 days of culture was required, and culturing the marginal zone of mantle was more optimal than culturing other areas. Additionally, it was shown that simple medium consisting of basal medium, fetal bovine serum and antibiotics could stimulate cellular proliferation followed by metaphase spread preparation.

Keywords: adult abalone; culture; karyotyping; mantle; metaphase spreads.
