Abstract

This work was performed with L 428, a cell line established in 1978 from a patient with Hodgkin's disease. These in vitro cells represent counterparts of in vivo Hodgkin and Sternberg‐Reed cells. L 428 and its derived sublines produce a significant amount of colony‐stimulatling factor (CSF) compared to standard preparations of CSF (fetal liver conditioned medium). Hodgkin‐cell‐derived conditioned medium, tested in cord‐blood assays and in semi‐solid agar systems, induced myeloproliferation predominantly. Production of CSF is independent of fetal calf serum concentration in the cultures. L 428‐conditioined medium could provide an excellent source for characterization and purification of granulocyte CSF.

## BACKGROUND. The predeliction for prostate carcinoma cells to metastasize to bone suggests the hypothesis that bone and/or bone marrow-derived factors may promote prostate carcinoma cell growth or survival, or serve as chemoattractants for these cells. METHODS. We screened three prostate carcino
