Tony Ting, PhD, Bone Therapeutics SA, Gosselies, Belgium, discusses challenges associated with developing cell therapies for clinical use. Chemistry, Manufacturing and Controls (CMC) remains a major barrier for many manufacturers, which lead to the creation of genetically engineered induced pluripotent stem cell-(iPSC)-derived mesenchymal stem cells (MSCs). Dr Ting additionally highlights how genetically engineered therapies can overcome regulatory issues relating to potency assays. This interview took place at Advanced Therapies Week 2022.
