Gene Therapy Approach, Tested on Liver Cells and Mice, Seen as Potential Treatment for Hemophilia B
Researchers, working with mice, have developed a new way of producing substantial numbers of gene-corrected liver cells with the possibility of repopulation in vivo. The strategy, which relies on the liver’s unusual regenerative skills, may hold promise for the treatment of diseases such as hemophilia B. The study by scientists at Oregon Health & Science University,…
