These are the brew of stem cells that can be obtained from the amniotic fluid as well as the amniotic membrane. The human amniotic fluid stem (AFS) cells are fortunate cells for therapeutic schemes that can be naturally changed to express therapeutic proteins. HAFSCs exhibit a natural tropism to cancer cells in vivo. They can be useful in tumour cells targeting. Further, they are easily available from surplus diagnostic samples during pregnancy and less ethical and legal concern are associated with the collection and application than other putative cells are subjected.
