CellTrack Information

CellTrack tracks where cell and gene therapies actually go in the body, in real time. Most CAR-T, Treg, and cell-therapy developers still rely on endpoint biopsies and terminal studies to piece together biodistribution. That leaves sponsors guessing about potency, persistence, and off-target risk until it's too late to change course. Our platform, TrackTGL, labels therapeutic cells, and cell-membrane particles like exosomes and lentiviruses, with zirconium-89, then follows them in vivo by PET imaging. We pair it with AcouTrack, an acoustic-wave labeling and washing system that avoids the variability that comes from older, chemistry-based labeling methods. CellTrack spun out of the University of Wisconsin-Madison and was built in partnership with WARF. We're running pilot studies with an academic research partner and have signed development agreements with CAR-T and Treg developers. In August 2026, we won the Pressure Chamber, the Greater Madison Chamber of Commerce's pitch competition and the closing event of Forward Fest. We strongly believe that you shouldn't have to guess where your therapy ends up. If you're developing a cell or gene therapy, let's talk.
