FibroBiologics shows preclinical disc‑height improvement with FSdC spheroids at NASS 2026
FibroBiologics presented preclinical data on its fibroblast spheroid‑derived chondrocyte (FSdC) therapy at the North American Spine Society 2026 Annual Meeting in San Antonio. The study used a 12‑week rabbit model of degenerative disc disease and compared a single injection of FSdC spheroids, conventional 2D fibroblasts and 3D fibroblast spheroids against a control. FSdC spheroids achieved the highest normalized percent disc height index (%DHI) of 80.7% versus 71.8% in controls, with statistically significant improvements over all groups. Company scientists highlighted chondrogenic differentiation and matrix remodeling as key mechanisms.
Why it matters
The company’s press release suggests the FSdC results could advance its pipeline toward clinical trials for disc degeneration, potentially creating a novel, cell‑based therapeutic option. If successful, this could broaden FibroBiologics’ addressable market and support future revenue growth.
