Problem
Current methods of preserving biological materials, such as cells, tissues, and organs, often rely on freezing, which can cause cryoinjury and reduce viability. Existing preservation protocols and solutions have seen limited innovation in the past 50 years, leading to suboptimal clinical outcomes and high unmet medical needs in organ transplantation and cell/gene therapies.
Solution
CryoStasis has developed a biopreservation platform, called Woolii™ SU, that enables the subzero unfrozen storage of biological material to maintain optimal cell viability and function. The platform uses a novel cold chain management process that combines proprietary media, temperature, and pressure controls to preserve biological material indefinitely. The media leverages cold shock inhibitors and membrane protectants to prevent cryoinjury to cells. The temperature systems include devices and shipping solutions to ensure viability and seamless integration into manufacturing and logistics. The pressure systems lower the freezing point and cell metabolism, enabling long-term storage.
Target Audience
The primary customers are doctors, researchers, and companies in the healthcare and research industry, specifically those involved in cell and gene therapy, regenerative medicine, and organ transplantation.
