Precision Animal Models and Organoids Core (PAMOC)

The DDRCC PAMOC has two components.  The mouse genetics component subsidizes services provided by the Mouse Genetics Core (see Mouse Genetics Core entry for details) for digestive diseases-related research. These include production of conventional transgenic mice by microinjection of DNA constructs and editing of the mouse genome (Indels, point mutations, insertion of loxP sites and reporters) by either microinjection or electroporation of CRISPR/Cas9 reagents into zygotes.  CRISPR approaches are implemented in collaboration with the Genome Engineering and Stem Cell Center (GESC).  The core also performs in vitro fertilization.

The organoid component (directed by Dr. Matt Ciorba) provides comprehensive services for the derivation, growth, transfection, and analysis of mouse and human GI Organoids.  Please contact Dr. Ciorba (mciorba@wustl.edu) to discuss access to organoid services.

Service available to Specific groups, centers or departments – see Additional Information for details.

Priority service for Washington University only.
