Stem cells in children can trigger the development of a brain tumor, brain cancer before it becomes difficult to cure. It expressed the researchers from the University of Queen Mary in London recently. These findings certainly adds to the chances of making the drugs to cure brain cancer in children.
A Tumor that invades the brain child of Medulloblastomas, can occur at the age of three to eight years, though by no means children under the age of three years will not be attacked this malignant disease. According to doctor Silvia Marino, medulloblastomas became a challenge for physicians. "In some children, the treatment went well, but on the other cancer became very aggressive and hard to be cured," explains Professor neropatologi University of Queen Mary.
In previous research, the human brain is found to have some stem cells are called neural stem cells. This part of the proper functioning of the brain to repair the damage caused by a tumor until at a certain level. "This research into major findings because for the first time we can show the development of endogenous on stem cells," explained doctor Marino.
According to scientists, tumor type Medulloblastomas often make pengidapnya only has little chance of healing. "This discovery is important with two reasons; First, this result can be direct care like what is needed, and where body parts that need to be dealt with intensively. Second, understanding here will help us create more anti-cancer medications on the child's brain, "said doctor Marino.
A new breakthrough that researchers from Oxford University have developed a new method to isolate cancer stem cells. If could do treatment against these cells in particular, we can eradicate the cancer to vanish.
To date research on cancer stem cells is too slow, because the cells are difficult to identify and isolate the tumor. In the past, scientists have been trying to find the cancer stem cells in tissue samples taken from patients. Thus the Telegraph, Tuesday released (26/1).
New research more engaging way this time using molecular markers to identify cancer stem cells and the cells in a laboratory. Researchers found, the proportion of cancer stem cells in different colon cancer vary widely, with a high risk of aggressive tumors.
Dr. Trevor Yeung from Oxford University explains, radiotherapy and chemotherapy is working against the cells quickly. But there is increasing evidence that cancer stem cells are more resistant than other cells for the treatment of this. Cancer stem cells that have not been destroyed later can relapse into cancer.
"People assume that cancer stem cells comprise a small percentage of cells in a tumor, but this is not true. The most aggressive tumors can have most of the cells, cancer stem cells, "he said.
