Pharmacological and Functional Genetic Assays to Manipulate Regeneration of the Planarian Dugesia japonica

¹Department of Pharmacology and The Stem Cell Institute, University of Minnesota Medical School

An attractive model for studying stem cell differentiation within a live animal is the planarian flatworm. Regeneration is studied by simple amputation experiments that are easily performed in a basic laboratory and are amenable to pharmacological and genetic (in vivo RNAi) manipulation as detailed by protocols in this article.

¹Department of Surgery, Division of Thoracic and Foregut Surgery, University of Minnesota, ²University of Minnesota Medical School

Redo foregut surgery is associated with increased patient morbidity and presents a technical challenge for the surgeon. We describe our approach and considerations when performing a redo hiatal hernia repair to provide a guide for other surgeons and improve patient outcomes.
