A great deal of PWS research uses cellular and animal models. Below is a list of some of the most commonly used PWS cellular models and animal models. Each table includes a brief description of the model, a link to the primary publication, and Principal Investigator (PI) information. Additional PWS iPSC models are currently in development; please contact us for additional information.

Animal Models
This table of PWS animal models was adapted from the publication by Resnick et al, outlining recommendations for the investigation of animal models of PWS. For the full list of PWS models, see the publication here. Additional PWS animal models are currently in development; please contact us for additional information (theresa.strong@fpwr.org).
