Generally speaking, some claim that women should be paid a fair wage for their reproductive labour or tissues, while others argue against the further commodification of reproductive labour or tissues and worry about voluntari...

Microglia is considered the only cell population of mesodermal origin, which comprises 10% of the cells in brain parenchyma. Recent neural stem cell (NSC) studies demonstrate that the brain has regenerative potential. NSCs do not give rise to microglial cells, however indicating that NSCs alone cannot complete the regenetion of the brain. Although the role of microglia is not fully understood, ...
