Lung adenocarcinoma (LAC) is a common and aggressive form of lung cancer that is increasing in incidence among never smokers at a younger age. Current treatment of patients with LAC is insufficient and there is a need for identification of effective biomarkers and development of therapeutic targets. These demands require also unproved models for in vivo and in vitro experimentation. In this study, we describe the establishment of two LAC cell lines, named LuCa-3 and LuCa-6. Both were derived from pleural effusion (PE) cells of LAC patients (13 and 16) and readily propagated as tumor xenografts in immunodeficient mice. PE cells from the patient L6 exhibited also the capacity for in vitro growth and were cultured in two forms: (i) as a suspension growing cell population, labeled LuCa-6S, composed of non-clumping single cells; and (ii) as a monolayer-like culture, labeled LuCa-6A, exhibiting tight cell-to-cell and to culture surface adherence. Unique features of these two sublines and their cell clones are the capacity to convert from a non-clumping single-cell suspension into the adherent growth pattern and vice versa. Immunostaining of patients' tumor tissue xenografts and cultured subline cells displayed markers specific for the phenotype of human LAC. LuCa-6S and LuCa-6A cells did not reveal a noticeable disparity in quantitative growth characteristics. However, a number of differences were detected between these two cell populations manifested in detection or intensities of antigen expressions on the cell surface (CD133, SFTPC) and in the nucleus (TTF-1) including pluripotcnt (OCT-4, SOX-2, NANOG) genes in cancer stem-like cells (CSCs). Dissimilarities between these two sublines were also detected in N-glycan profiles and in the sensitivity to natural killer cells. Salient features of these subline cell populations are responsiveness to selective upregulation of the pluripotent genes in subsets of CSCs via conversion of their growth patterns and/or by using culture stem media with growth factors. The described in vivo/in vitro model enables broader experimental approaches in studies of lung adenocarcinoma.
