โœฆ Synopsis

It has been shown that a dialyzable substance produced by normal and tumor cells can stimulate the growth of a myeloid, erythroid, and two lymphoid leukemias, and a sarcoma. The growth stimulation of the tumor cells was observed as an increase in cloning efficiency and number of cells per colony. Rat granulocytes stimulated the growth of mouse tumor cells as efficiently as a variety of mouse cells, The stimulating substance was found in conditioned medium, and it was produced by all the normal and tumor cells tested.

Bone is one of the most common sites of metastasis in melanoma and breast cancer cells. Human melanoma (A375M) and human breast cancer (MDA-MB-231) cells form osteolytic bone metastasis in vivo when these tumor cells are injected into the left ventricles of BALB/c nude mice. These tumor cells promot
