Sigilon Therapeutics is a biopharmaceutical company creating functional cures for chronic diseases using Shielded Living Therapeutics. To create Shielded Living Therapeutics, we engineer novel human cells that we encase in a proprietary immune-shielding matrix and place in the body. These Shielded Living Therapeutics then produce therapeutic proteins in a programmable and durable fashion, without generating fibrosis or immune rejection. Sigilon was founded and created by Flagship Pioneering in conjunction with Daniel Anderson, Ph.D., and Robert Langer, Sc.D., of the Massachusetts Institute of Technology.
