Meristem

Meristem Therapeutics was a French biotechnology company focused on producing therapeutic recombinant proteins in plants for pharmaceutical applications. Its core capability was a plant-based biomanufacturing platform designed to take programs from gene construct through large-scale production and purification, with particular relevance for high-volume proteins and antibodies. Historical materials describe programs and intellectual property around recombinant human lactoferrin and other plant-made biologics rather than a broad late-stage clinical pipeline. The company appears to no longer operate economically: French government records classify the legal entity as dormant or presumed inactive with all establishments closed. Meristem Therapeutics was publicly listed in Paris historically, but available evidence indicates it is no longer an active operating biotech business.
