In the case published in the Proceedings of the National Academy of Sciences, researchers use genetic research to prove if cancer cells have been transferred from mother to child. The mother is 28 years old Japanese woman who was diagnosed with leukemia after giving birth, and his daughter 11 months old also suffered the same type of cancer.
According to researchers in the last 100 years has been several reports of the discovery of cancerous cells in the baby's mother. This, they say, showed a possible reduction in cancer cells from mother to fetus. "But he has not yet been proven genetically," said the researcher.
The results of genetic tests showed the cancer cells have a baby with a genetic match of cancer stem cells. Special signs in babies of cancer cells to prove that these cells come from the mother.
In addition, the results of further tests showed that cancer cells in babies lose some genetic material, material that is believed lost as a marker of cancer cells are abnormal cells, and was eliminated by children's immune systems. This genetic trait, according to researcher Takeshi Isoda, allowing the mother to cancer cells, avoiding the protective layer of the placenta of the fetus.
