Nanoparticles may prove effective tools for improving stem cell therapy, new research suggests. Chemical engineers have successfully used nanoparticles to enhance stem cells' ability to stimulate regeneration of damaged vascular tissue and reduce muscle degeneration in mice, they report in a study published online today (October 5) in Proceedings of the National Academy of Sciences.
"This is an intriguing finding," said linkurl:Arnold Kriegstein,;http://bms.ucsf.edu/faculty/kriegstein.html a regenerative biologist at the University of California, San Francisco, who was not involved in the study. "But it would need to be explored a good deal further before one could really be excited about this new approach." Researchers studying linkurl:the role of stem cells in stimulating new blood vessel formation;http://cardiovascres.oxfordjournals.org/cgi/content/full/56/3/357 have suggested that after implantation into a living organism, cells may not continue to renew tissue effectively enough to keep the tissue alive long-term. The cells can therefore benefit from help...
