This was done on cells in a lab, not in people. It is a very early step.
This was lab work on tissue samples, not a treatment tried in people.
The short version
Scientists built a new way to study the blood vessels at the outer edge of glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary, a brain tumor.
What was studied. Researchers used human tissue samples of glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary and the brain next to it. They stained the blood vessels, then used a computer program to sort the vessels by shape and makeup.
What they found. The staining worked for the vessel markers they tested. The computer sorted the vessels into four groups. The edge areas had the fewest blood vessels. Some vessels there were unlike vessels anywhere else. Others looked like vessels in the tumor center or in normal brain.
What this means, and what it doesn't
What it could mean: The edge of a glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary is hard to remove with surgery, and drugs have a hard time reaching it. This tool may help scientists learn why. Over time, that could help others design drugs that reach those cells.
What it doesn't mean: This is not a treatment, and it is not a cure or a promise of one. No one was treated in this study. It was lab work on tissue samples, not a test in people. It is a long way from anything your doctor can offer today.
