Obtaining Primary Ovarian Cancer Cells from Solid Specimens: A Method to Culture Epithelial Ovarian Cancer Cells from Ovarian Tumor Specimens

Abstract

Source: Pribyl, L. J. et al. Method for Obtaining Primary Ovarian Cancer Cells From Solid Specimens. J. Vis. Exp. (2014)

In this video, we describe a method for isolating and characterizing primary ovarian cancer cells from solid ovarian tumor tissue specimens. The epithelial cancer cells obtained using this protocol are suitable for understanding the processes that may lead to ovarian cancer initiation and development.

Protocol

All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board.

1. Tissue Processing

1. Working under sterile conditions, transfer the samples onto a Petri dish (60 mm x 60 mm) containing 10 ml of fresh, ice-cold PBS and using a sterile razor blade, further cut into the smallest pieces possible (2 mm or less) (Figures 1A and 1B).
2. Transfer the minced tissues into a 15 ml conical tube containing 10 ml of prewarmed (37 °C for 30 m....

Results

Figure 1. Processing of clinical specimens. A) Solid specimen transferred onto a Petri dish containing 10 ml of fresh, ice-cold 1x PBS. B) Clinical specimens further cut into pieces about 2 mm in size
