The lack of available, well characterized, established, domestic porcine cell lines hinders the advancement of porcine cellular immunology. A case of multicentric lymphoma was diagnosed in a market weight pig at the time of slaughter. Affected lymph nodes and spleen were collected and used for single cell isolation and analysis. Cell lines were established by 3 rounds of limiting dilution from splenic and subiliac lymph node lymphomas. Surface marker staining identified the cells as CD21+, CD79a+, CD20+, PAX5+, and CD3- and cells were grown and easily passaged in cell culture. Transcriptome analysis was carried out to further characterize these rapidly proliferating cells validating the initial cytometric findings, confirming their identity as B cell lymphomas, and suggesting that they arose from germinal center centroblasts with aberrant control of BCL6 expression. Functional analysis identified the cells as being involved in cancer, cell movement, cell survival, and apoptosis. These new porcine B cell lymphoma cell lines will be a valuable resource for more in-depth cellular investigations into the porcine immune system and cancer, as well as providing a potential tool for the growth of lymphotropic viruses of pigs and humans.
