This was done in animals, not people. Most findings at this stage never become treatments.
This was early lab research and has not been tested in people.
The short version
Lab research suggests helper cells in the brain may pass energy parts to resting tumor cells, helping them grow again.
What was studied. Researchers looked at glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells that sit quietly at the edge of a tumor. They studied how nearby brain support cells, called astrocyte: A star-shaped helper cell in the brain and spinal cord. It is one of the glial cells that sit around nerve cells. An astrocytoma starts in these. See the glossary, might wake these resting cells up.
What they found. The support cells seemed to pass tiny energy parts, called mitochondria, into the tumor cells. These parts carried a helper protein that changed how the tumor cells worked. This helped the tumor cells grow fast and hide from the body's defense system. Blocking this handoff slowed the waking of resting cells and delayed tumor growth.
What this means, and what it doesn't
What it could mean: This points to a possible weak spot in glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. In the future, doctors might try to block this handoff to keep resting tumor cells from growing back.
What it doesn't mean: This does not mean there is a new treatment. This was early lab research, not a study in patients. It will take many years of testing to know if blocking this could help people. It is not a cure.
