Changes of T cells and RORγt⁺ cells in NEC patients. Representative immunofluorescent staining pictures, and the statistical analyses of the count of CD3e⁺ T cells (a–c) and RORγt⁺ cells (d–f). n = 4 per group. Data were shown as mean values ± SD. Statistical analyses were performed with Student’s two-tailed unpaired t-test. **p < 0.01. Scale bars represent 50 μm. Ctrl, tissue from neonatal intestinal atresia patients. The Y-axis means total cell number in a visual field of one patient’s terminal ileum (c, f)
