A Swedish group has successfully tested a new porous material that allows for the efficient delivery of key molecules to transplanted cells that have been derived from stem cells. Such a material can dramatically improve the way stem cell-based treatments for neurodegenerative diseases.
This research project included a collaboration between Danish, Swedish and Japanese laboratories, and it tested a new type of porous material that efficiently delivers key molecules to transplanted cells derived from stem cells in an animal model.
This potentially versatile and widely applicable strategy for the efficient differentiation and functional integration of stem cell derivatives upon transplantation, and it can serve as a foundation for improving stem cell-based neurodegenerative protocols, for example, Parkinson’s disease.
Alfonso Garcia-Bennett of Stockholm University, one of the lead authors of this study, said: “We are working to provide standard and reproducible methods for the differentiation and implementation of stem cell therapies using this type of approach, which coupled material science with regenerative medicine.”
Garcia-Bennett continued: “We demonstrated that delivering key molecules for the differentiation of stem cells in vivo with these particles enabled not only robust functional differentiation of motor neurons from transplanted embryonic stem cells but also improved their long-term survival.”
This research group is already working together with two companies to speed up the commercialization of a standard differentiation kit that will allow other scientists and clinicians to reproduce their work in their own laboratories.
