In fact, we did lose the cell, which is a big reason damaging the root cause of suffering from dementia and head injuries. 瓦德莱 said: "However, there are two parts of the brain cells self-renewal, dominate our sense of smell in the olfactory bulb and hippocampus projections for learning."
4 Cardiac Life: 20 years
Before people always thought that the heart can not self-update. However, one study found that New York Medical College, covered constantly self-renewing stem cells on the heart, they are lifetime updates at least 2-3 times.
5 lung Life: 2-3 weeks
