Culture of equine intestinal epithelial stem cells after delayed tissue storage for future applications

BMC VETERINARY RESEARCH, 18(1).

By: A. Stewart n, C. Schaaf n, B. Veerasammy n, J. Freund n & L. Gonzalez n

author keywords: Horse; Stem cell; 3D culture; Organoid; Enteroid; Intestine; Storage
MeSH headings : Animals; Cryopreservation / veterinary; Epithelial Cells / cytology; Horses; Intestines / cytology; Stem Cells / cytology; Time Factors; Cells, Cultured; Intestinal Diseases / therapy; Intestinal Diseases / veterinary
TL;DR: Equine ISCs can be isolated and cultured after prolonged tissue storage and this suggests that ISCs could be isolated for several days from samples properly stored after procedures, including surgery or necropsy, and used to create ISC repositories for study or therapy of equine intestinal diseases.
