In brief
This review examines experimental models used to study necrotizing enterocolitis (NEC), from in vitro intestinal cell cultures and organoids to in vivo animal models. The article discusses how these research platforms have advanced understanding of NEC pathogenesis and informed development of preventive and therapeutic strategies for this high-mortality preterm intestinal disease.
Written by the GCMD Library team from the article.
Necrotizing enterocolitis (NEC) is a devastating intestinal disease that continues to have high morbidity and mortality among preterm neonates, despite medical advancements in neonatology and neonatal care. To investigate the pathogenesis of the disease and explore novel form of treatment, a variety of experimental models of NEC have been developed and used by various investigators. These experimental models range from in vitro evaluation of intestinal epithelial cells and intestinal organoids to in vivo models of the disease in neonatal mice, rats, and piglets. Most recently, human-derived intestinal organoids have also been developed and investigated. In this review, we will briefly discuss these experimental models and the contributions that they have made to our understanding of NEC. We will also point to the ischemia/reperfusion (I/R) model of intestinal injury which has been used as an indirect model of NEC by some investigators. Advancements in laboratory research into this devastating disease have continued to expand our knowledge on the pathogenesis and prevention of NEC as well as the effectiveness of therapeutic options for management of this severe disease.
