Amniotic Epithelial Cell Expansion
Because there is not a sufficient amount of amniotic epithelial cells extracted from a single term placenta to be use in cellular therapies, the cells must be expanded in a lab. However, some studies have shown that once these cells are duplicated in the lab, some of the pluripotentency is lost. Also, these lab grown cells have shown altered gene expression causing a differing phenotype as well as differing antigen levels. This may change their ability to be compatible across non related tissues. 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.

Famous quotes containing the words cell and/or expansion:
“She that but little patience knew,
From childhood on, had now so much
A grey gull lost its fear and flew
Down to her cell and there alit,
And there endured her fingers’ touch
And from her fingers ate its bit.”
—William Butler Yeats (1865–1939)
“Artistic genius is an expansion of monkey imitativeness.”
—W. Winwood Reade (1838–1875)
