This was done on cells in a lab, not in people. It is a very early step.
This was lab work on stored tumor tissue, not a treatment.
The short version
Some brain tumors that spread from other cancers hold a tough support tissue, and this study looked at what cells are in it.
What was studied. Researchers looked at stored tumor tissue under a microscope. They checked 19 brain tumors that had spread from carcinomas, 10 glioblastomas, and 20 carcinomas from the original site. They used stains that mark a kind of support cell.
What they found. In the 19 brain tumors that had spread, the support cells matched the look of a helper cell seen in other cancers. The stains were much stronger in these tumors than in the 10 glioblastomas. The cells did not look like brain cells or blood vessel cells.
What this means, and what it doesn't
What it could mean: This adds to what doctors know about how these tumors are built. Over time, that kind of basic knowledge can point researchers toward new things to test.
What it doesn't mean: This is not a treatment, and it is not a cure. It was lab work on stored tumor tissue seen under a microscope. No one was treated, and nothing here was tested in people. Anything useful for everyday care is far off, if it comes at all.
