Similar percentage of CD8⁺CD103⁺ and CD8⁺NKg2a⁺-cells in RE and other squamous esophageal biopsies.

<p>Panel A depicts percentage of CD103⁺-cells percentage of the population of CD8⁺-cells (CD8⁺CD103⁺) in 14 days <i>ex vivo</i> culture of squamous epithelial biopsies from controls (C SQ 5 cm: 5 cm above the Z-line), RE patients and (RE 5 cm: 5 cm above the inflamed RE tissue) and BE patients (BE SQ 5 cm: 5 cm above the BE tissue). Panel B represents CD8⁺CD103⁺- percentage in 14 days <i>ex vivo</i> culture of normal looking distal squamous epithelial biopsies of controls (C SQ 2 cm: 2 cm above the Z-line) and inflamed esophageal tissue of RE-patients (RE). Panel C depicts percentage of NKg2a⁺-cells of the population of CD8⁺-cells (CD8⁺NKg2a⁺) in 14 days <i>ex vivo</i> culture of squamous epithelial biopsies from controls (C SQ 5 cm: 5 cm above the Z-line), RE patients and (RE 5 cm: 5 cm above the inflamed RE tissue) and BE patients (BE SQ 5 cm: 5 cm above the BE tissue. Panel D represents CD8⁺NKg2a⁺-percentage in 14 days <i>ex vivo</i> culture of squamous epithelial biopsies of controls (C SQ 2 cm: 2 cm above the Z-line) and inflamed esophageal tissue of RE-patients (RE). Panels A and C: Kruskal-Wallis test. Panels B and D: Mann-Whitney test. Mean value and SEM are calculated.
