ROS1 and lung carcinoma: Of note, currently only one lung cell line (HCC78) carrying a ROS1 fusion (SLC34A2-ROS1) is available from a public biobank (DSMZ-German Collection of Microorganisms and Cell Culture GmbH), thus this additional lung tumoroid line (TPM3-ROS1) that we generated here would be useful for the lung cancer research community.
