Laboratory Maintenance and Propagation of Freshwater Planarians
Makayla R. P. Dean, Elizabeth M. Duncan
Abstract
Freshwater planarians are a powerful model organism for the study of animal regeneration, stem cell maintenance and differentiation, and the development and functions of several highly conserved complex tissues. At the same time, planarians are easy to maintain, inexpensive to propagate, and reasonably macroscopic (1 mm to 1 cm in length), making them excellent organisms to use in both complex academic research and hands-on teaching laboratories. Here, we provide a detailed description of how to maintain and propagate these incredibly versatile animals in any basic laboratory setting. © 2020 Wiley Periodicals LLC.
