The amnion is the innermost layer of the placenta, a layer of translucent film that is formed by the interconnection of single layer of epithelial cells. Stroke is a group of diseases characterized by brain ischemia and hemorrhagic injury, with extremely high morbidity and mortality. Stroke is mainly divided into two categories: hemorrhagic stroke (cerebral hemorrhage) and ischemic stroke (cerebral infarction).
Researchers at Le Tropez University and Monash University have found that injection of human amniotic epithelial cells is expected to be used for ischemic stroke treatment.
The researchers found in animal experiments that after a 1.5-hour stroke, human amniotic epithelial cells were injected intravenously, and these cells quickly entered the damaged area of ​​the brain, significantly reducing inflammation and reducing nerve cell death. Even after injection of human amniotic epithelial cells 1 to 3 days after stroke, the healing process can be accelerated and the functional recovery of the body can be improved.
In a press release issued by the school, Professor Chris Sobi of Lezhuo University, who led research, said that injection of human amniotic epithelial cells is an effective cell therapy. Amniotic epithelial cells are a kind of amnion stem cells, which retain the characteristics of embryonic stem cells, have strong differentiation potential and immune tolerance, will not be rejected by the human body, and will not cause cancer. The amniotic tissue is a relatively easy to obtain postpartum waste, which does not lead to ethical debate.
The research results have been published in the American Journal of Stroke. It is understood that researchers at Monash University who are participating in the research will conduct relevant human clinical trials in the near future to further evaluate the feasibility and safety of this method.
