The clonal growth of cell lines from some human solid tumours can be stimulated by haematopoietic growth factors such as recombinant human (rh) interleukin-3 (IL-3) and rh granulocyte-macrophage colony-stimulating factor (GM-CSF) in vitro. Among these cell lines are the human colorectal adenocarcinoma cell line HTB 38 and the human small-cell lung cancer cell line HTB 119. Here we report on a series of experiments studying the influence of subcutaneously administered rhIL-3 and rhGM-CSF on the in vivo growth of HTB 38 and HTB 119 cell lines as xenografts in athymic nu/nu BALB/c mice. Beginning 1 day after transplantation of the tumour the cytokines were administered daily for 20 days as a subcutaneous bolus distant from the tumour lesion at dose levels up to 1 mg/m2/day. The cytokines caused no significant and reproducible growth modulation of the tumours in vivo.

We have studied the effect of recombinant human hematopoietic growth factors (interleukin-3 [rhIL-3], granulocyte-macrophage colony-stimulating factor [rhGM-CSF], and granulocyte CSF [rhG-CSF]) on the clonal growth of human colon adenocarcinoma cell lines HTB-38, CCL 187, and WiDr (CCL 218). The factors stimulated clonal growth of HTB-38 and CCL 187 in a capillary modification of the human tumor clonogenic assay in agar up to twofold. There were dose-response correlations over a range of 1 to 10,000 U/mL for rhIL-3, rhGM-CSF, and rhG-CSF. Incubation with neutralizing monoclonal antibodies abolished the stimulation of clonal growth by rhGM-CSF. The WiDr cell line was nonresponsive to rhIL-3 and rhGM-CSF. These results represent the first evidence that a variety of hematopoietic growth factors can stimulate the growth of clonogenic cells of some nonhematopoietic malignant cell lines in vitro.
