This service provides in-depth protocols, hands-on training, biologics, and ongoing support for the derivation and culture of gastrointestinal organoids/enteroids/mini-guts from stomach, small intestine, or colon of mouse or human.
The L-WRN cell line (L cells expressing Wnt3a, R-spondin3, and Noggin) is maintained and aliquots of conditioned media are available.
The R-Spondin cell line (293T cells expressing mouse R-Spondin1) is maintained and aliquotes of conditioned media are available.

Logistics:
Investigators are trained in organoid culture by Core scientists (David Breault, MD, PhD and Amy O’Connell, MD, PhD) and staff. The Core helps investigators to establish this technology within their own labs, by providing the resources for a “pilot experiment” using primary tissue provided by the investigator or the core as needed. Methods include isolation of crypts/glands from primary tissues, suspending them in Matrigel, culture in defined or conditioned media, and monitoring organoid health. Methods to perform viral transduction, organoid freeze down, fluorescent imaging of live cultures and post-fixation histological applications are also available. Consultation is provided to HDDC members (at no charge).
Quality Control:
L-WRN conditioned media used for organoid generation are routinely assayed for Wnt-3a activity.
