The production of high-quality mammalian cells remains a bottleneck, limiting productivity across the biomedical R&D landscape—from basic research to translational sciences, and therapeutics manufacturing. XDemics Corporation, a Caltech spin-out, has solved this challenge with our proprietary High-Density Cell Respiration™ (HDCR™) laboratory cultureware and bioreactor products. These products permit tissue-level oxygenation, allowing cells to reach 10–100X higher densities than conventional devices, near the theoretical limit of achievable densities for cell growth. With HDCR™, researchers and manufacturers can generate far more high-quality viable cells and products with less sheer-induced debris in much less space and time, sharply cutting costs, speeding discovery, production, and increasing quality and reproducibility. XDemics is the proud winner of the 2026 SLAS Ignite Award for best start up.
