Amniotic epithelium is derived from the epiblast by approx 8 d after fertilization. Other parts of the placenta are derived from extraembryonic tissue. In addition to this developmental difference, amniotic epithelial (AE) cells are known to have unique characteristics, such as low level expression of major histocompatibility complex antigens, and a less restricted differentiation potential. The differentiation of the AE cells to the neural lineage is well documented. Recently, we reported that AE cells from term placenta express several stem cell surface markers that are commonly found on pluripotent stem cells such as embryonic stem cells, and that in culture, AE cells differentiate into cell types from all three germ layers. In this review, we describe the unique characteristics of the AE stem cells and summarize previous work concerning the stem cell nature of cells from amnion.

D015195 Drug Design The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include PHARMACOKINETICS, dosage analysis, or drug administration analysis.
