What we do

bit.bio is a synthetic biology company providing human cells for research, drug discovery and cell therapy. The company applies a patented safe harbour gene-targeting approach (opti-ox™; Pawlowski 2017) to inducibly express transcription factor combinations that reprogram human induced pluripotent stem cells (iPSCs) into highly defined and mature human cell types. 

The required transcription factor combinations are discovered using high throughput screens and advanced data analysis (bit.bio discovery platform). The company is currently building a clinical pipeline and marketing a wide range of cells and disease models for research and drug discovery under its ioCells brand including nerve cells, immune cells and muscle cells. 

The company was spun out of the University of Cambridge in 2016 and has since raised approximately $200M from Arch Ventures, Foresite Capital, Milky Way, Charles River Laboratories, National Resilience, Tencent, and Puhua Capital among others.
