Tritiated thymidine and Ehrlich ascites tumour cells were injected intrathecally in adult Balb/c mice. Thymidine penetrated easily into the sphenoid bone marrow, where it labelled numerous leukocytes. The microvessel wall constituted a partly penetrable barrier against the infiltration of Ehrlich ascites tumour cells from arachnoid space into the bone marrow. A possible physiological role of the drainage of substances from the brain into the bone marrow is discussed.
