Interestingly, while there was a trend to increase leukocyte adhesion at 6 h for NSCLC-TECs (and particularly for A549-TEC that expressed the higher level of ICAM-1 and VCAM-1) (Fig. 2E; Supplementary Figure S3B), this effect was lost after 24 h of culture (Supplementary Figure S3C). Here, VCAM1 is linked to non-small cell lung carcinoma.
