Stem cells can be a cause of cancer spread

US scientists believe that dangerous changes in cancer cells enable them to spread throughout the human body, possibly caused by the body's own stem cells.

A team from the Whitehead Institute said that when they " mix " human breast cancer tumors with their human stem cells and then put them into mice, the cancerous tumor is capable of spreading. The lung is seven times larger than its normal ability to spread on the body.

Breast cancer cells. They found that the appearance of cells in cancer tumors has caused genetic changes in cancer cells that make these cells likely to cause metastatic cancer. But as soon as these cells spread, they changed back to their original gene state.

"This not only makes these key genes difficult to detect, but also means that it is possible to prevent or reverse dangerous changes in cancer cells, making the block The cancer is not metastatic and therefore much easier to treat, the risk of death of the patient will also decrease.

Middle tissue stem cells are detected in the bone marrow, and the 'key cell' used by the body to help produce new bone, fat, cartilage and muscle.

Scientists suspect that stem cells are a cause of cancer spread after they are found to be able to move in large numbers to areas where tumors are found. They think that, by understanding how a tumor suddenly changes and the cause of that change, it is possible to find a treatment to help prevent this change, and to keep the cancer tumor. This is fixed, not spread.

Dr. Kat Arney of the British Cancer Research Institute said the results of the study suggest that middle tissue stem cells may contribute to breast cancer spread. However, since research has only been carried out on mice, it is not possible to know exactly if everything is going to be exactly the same on human bodies.
