 Much of the effects of expanding these cells are unknown and scientists are continuing to study ways to cultivate these cells without changing their pluripotent properties.Scientists have found that freezing amniotic epithelial cells causes them to not function as they normally would, which have scientists thinking that the extracellular matrix is the part of the cell that controls its functions.There have been several studies conducted on the potential benefits of using amniotic epithelial cells in various parts of the body.
