Tóm tắt

Human induced pluripotent stem cells offer the possibility of generating unlimited quantities of cells for autologous transplantation. By correcting the genetic defect underlying Z-allele α1-antitrypsin deficiency, we recently provided the first proof of principle for application of human induced pluripotent stem cells in the treatment of inherited genetic disorders. Several important safety concerns will need to be addressed before this can be translated into clinical practice.
