Stem cells can help repair spinal cord after injurySpinal cord injury often leads to permanent functional impairment. In a new study published in the journal Science researchers at Karolinska Institutet show that it is possible to stimulate stem cells in the mouse spinal cord to form large amounts of new oligodendrocytes, cells that are essential to the ability of neurons to transmit signals, and thus to help repair the spinal cord after injury.

New CRISPR-Cas9 variant may boost precision in gene editingResearchers have developed a new variant of the gene editing technique CRISPR-Cas9 that has the potential to increase precision during gene therapy in humans. The new variant reduced unintended changes in DNA compared to its wildtype, suggesting it could play a role in gene therapies that require high precision. The study by researchers from Karolinska Institutet’s Ming Wai Lau Centre of Reparative Medicine in Hong Kong is published in the journal PNAS.
