There is an ever expanding field of research devoted to discovering further cell types in the cord, and uses for them. Perhaps of most importance is that the tissue of the umbilical cord is a rich source of mesenchymal stem cells. Biovault offer to freeze both cord blood – for the haematopoietic stem cells, and whole cord tissue -to facilitate the future potential of MSCs. Scientists continue to research the best methods to extract and grow cord stem cells and so better techniques may be developed than are used currently.
