				        	 Background and Objectives:The colonic epithelial layer is a complex structure consisting of multiple cell types that regulate various aspects of colonic physiology, yet the mechanisms underlying epithelial cell differentiation during development remain unclear. Organoids have emerged as a promising model for investigating organogenesis, but achieving organ-like cell configurations within colonic organoids is challenging. Here, we investigated the biological significance of peripheral neurons in the formation of colonic organoids. 
				        	
Methods:and Results: Colonic organoids were co-cultured with human embryonic stem cell (hESC)-derived peripheralneurons, resulting in the morphological maturation of columnar epithelial cells, as well as the presence of enterochromaffin cells. Substance P released from immature peripheral neurons played a critical role in the development of colonic epithelial cells. These findings highlight the vital role of inter-organ interactions in organoid development and provide insights into colonic epithelial cell differentiation mechanisms.
Conclusions:Our results suggest that the peripheral nervous system may have a significant role in the development ofcolonic epithelial cells, which could have important implications for future studies of organogenesis and disease modeling.
