Stealthy stem cells to treat disease

Posted by in categories: biotech/medical, genetics, health

Strategies differ, but there are some gene edits that all researchers agree must underpin any universal stem-cell-derived therapy. There is also widespread consensus that the optimal product should incorporate as few edits as possible, both to minimize the potential for unintended genetic consequences and to streamline manufacturing and regulatory approval.

Beyond that, the scientific community is divided. The complexities of the immune system have fuelled spirited debates over the exact genetic manipulations necessary to create a cell therapy that is both capable of bypassing immune defences and delivering meaningful health benefits.

“The immune system is pervasive and persistent,” says Charles Murry, a cardiovascular pathologist at the University of Washington in Seattle and chief executive of StemCardia in Seattle, one of a growing number of biotechnology companies developing gene-editing strategies to overcome immune barriers in regenerative cell treatments.
