Fluorescent In Situ Hybridization and 5-Ethynyl-2′-Deoxyuridine Labeling for Stem-Like Cells in the Hydrozoan Jellyfish Cladonema pacificum

Overview

This article presents a protocol for visualizing stem-like proliferating cells in the jellyfish Cladonema. By employing whole-mount fluorescent in situ hybridization with a stem cell marker and 5-ethynyl-2'-deoxyuridine labeling, researchers can identify both proliferating and non-proliferating stem-like cells.
