- Review
- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was only done with cells in a lab dish, not in people.
The short version
In a dish, some glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells spread farther when the gel around them gave way easily.
What was studied. Researchers made soft gels in the lab to act like the matrix that surrounds brain cells. They put glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary stem cells from patients into the gels and watched how the cells spread. The cells were sorted into three groups by their gene patterns, called Reactive, Invasive, and Constructive.
What they found. Each new gel let go of pressure faster than the plain base gel. The three cell groups did not all act the same way in the gels. Reactive cells spread more in the gels that let go of pressure fastest.
What this means, and what it doesn't
What it could mean: This helps explain why glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells spread the way they do. It also shows that not all tumor cells from the same person behave alike. It does not change any care or treatment you can get now.
What it doesn't mean: This is not a treatment, and it is not a cure. The work was done with cells in gels in a lab, not in people. No one was treated and no drug was tested. Years of more research would be needed before this could help anyone in the clinic.
