Washington: Scientists have developed sugar-coated scaffolding to improve stem cell technology to cure some of the world`s incurable diseases and conditions.Stem cells have the unique ability to turn into any type of human cell, opening up all sorts of therapeutic possibilities for diseases from Alzheimer`s to diabetes.But how to encourage stem cells to turn into the particular type of cell required to treat a specific disease is the problem that scientists are facing now.Now researchers at the University of Manchester`s School of Materials and Faculty of Life Sciences have developed a web-like scaffold, coated with long-sugar molecules, that enhances stem-cell cultures to do just this.The scaffold is formed by a process known as `electrospinning`, creating a mesh of fibres that mimic structures that occur naturally within the body.The team`s results are particularly promising, as the sugar molecules are presented on the surface of the fibres, retaining structural patterns important in their function. The sugars are also `read` by the stem cells grown on the surface, stimulating and enhancing the formation of neuronal cell types.
