  • Title: Studies on primary cell cultures derived from ovarian tissue of Penaeus monodon.
    Author: Fraser CA, Hall MR.
    Journal: Methods Cell Sci; 1999; 21(4):213-8. PubMed ID: 10627674.
    Abstract:
    As part of a bioassay approach to investigate ovarian development and function, primary cell cultures were derived from Penaeus monodon ovaries at various stages of maturation. These cultures were established in modified Grace's or modified 2x L-15 media. Various supplements including growth factors, vitamins and minerals were trailed. Four morphologically different types of cells (epithelioid, fibroblastic, rounded, and epithelioid with large nuclei) were maintained for up to 17 months. Epithelioid cells grew best in modified Grace's medium but were generally short-lived (less than two months). Fibroblast-like cells formed confluent monolayers in modified 2x L-15 medium, were passaged three times and survived for 17 months. In other cultures, millions of rounded cells migrated from tissue. They survived for prolonged periods (up to ten months), either loosely attached to the flask or suspended in the medium. A change in dominant cell type from fibroblastic to epithelioid was observed in some cultures after three or nine months incubation. These epithelioid cells which had very large nuclei, grew to confluence but could not be sub-cultured. It is noteworthy that the rounded cells and the epithelioid cells with the large nuclei both produced vitellogenin in protein-free media.
