Background & Aims: Organs of the gastrointestinal tract contain tissue-resident immune cells that function during tissue development, homeostasis, and disease. However, most published human organoid model systems lack resident immune cells, thus limiting their potential as disease avatars. For example, human intestinal organoids (HIOs) derived from pluripotent stem cells contain epithelial and various mesenchymal cell types but lack immune cells.

However, limited attention has been given to the circumferential aspect. This study aimed to investigate the prevalence and characteristics of ESCC lesions resected via endoscopic submucosal dissection (ESD), taking into consideration both longitudinal and circumferential positions.
