MCEC

Molecular and Cellular Engineering Corporation (MCEC) was a biotechnology company focused on the development of gene and cell therapies for genetic disorders. Founded by Dr. Savio Woo, a pioneer in gene therapy, the company specialized in non-viral gene delivery systems and treatments for metabolic diseases such as phenylketonuria (PKU) and hemophilia. MCEC's research emphasized the engineering of cells to produce therapeutic proteins, aiming to provide long-term cures for inherited conditions. The company was acquired in 1998 by Megabios Corporation, which subsequently merged with GeneMedicine to form Valentis, integrating MCEC's technology into a broader gene therapy portfolio.
