ILC2 adoptive transfusion in neonatal mice. A Neonatal mice were treated with an adoptive transfusion at day 7 during hyperoxia exposure. Neonatal mice in different groups were sacrificed at day 14. B In vivo imaging of Cy7-stained ILC2 in BPD mice; upper panel: whole-body imaging at 0, 6, and 30 h; lower panel: ex vivo imaging of the heart, lung, liver, spleen, kidney, and stomach at 30 h. C, D Representative results and percentage of ILC2 detected by flow cytometry in the lung tissues from the different groups. E IL-6 levels in the blood serum and lung tissues were assessed in different groups. Data presented are the mean ± SD (n = 6); ** P < 0.05
