Program Description:

The BioStabilization Systems (BoSS) program aims to transform how live cell-based therapies are stabilized, manufactured, and distributed. At its core, BoSS addresses a foundational bottleneck in the delivery of advanced cell and gene therapies (CGTs): the critical dependence on ultra-cold conditions (-80 to -196˚C) for storage and transport. BoSS will yield a bioprocessing system that enables scalable production of thermally stable cells, paving the way for a new era of efficient and resilient manufacturing and distribution of biologics without any need for cold storage. BoSS-developed technologies will also accelerate many other avenues in biotechnology that directly impact healthcare, including bio-surveillance, regenerative medicine, large-scale genetic testing, blood product supply, and wound repair, in addition to improving access to a wide range of existing biotherapeutics. 

Solution Summaries are required:
