Cellular Origins  

Cell therapies have been shown to cure devasting and previously untreatable diseases like cancer by re-programming the patient’s own immune system. Giving more patients access to these life-saving therapies requires a revolution in manufacturing and process automation.  

Cellular Origins, a TTP Company, is focused on enabling scalable, cost-effective and efficient manufacture of cell and gene therapies. Our technology addresses the challenges associated with manufacturing at scale with an elegant solution for automated sterile fluidic interconnection that reduces cost and labour, eliminates human error, and increases efficiency.
