Abstract
Amyotrophic lateral sclerosis (ALS) causes progressive degeneration of the motor neurons. In this study, we delivered the genetic construct including the whole locus of human mutant superoxide dismutase 1 (SOD1) with the promoter region of human SOD1 into porcine zygotes using intracytoplasmic sperm injection–mediated gene transfer, and we thereby generated a pig model of human mutant SOD1–mediated familial ALS. The established ALS pig model exhibited an initial abnormality of motor neurons with accumulated misfolded SOD1. The ALS pig model, with a body size similar to that of human beings, will provide opportunities for cell and gene therapy platforms in preclinical translational research.
