A Phase 1/2a clinical trial has demonstrated that intravenous infusions of autologous adipose-derived mesenchymal stromal cells (MSCs) are a safe and promising treatment for patients with chronic traumatic brain injury (TBI). The study, involving 24 patients, found that three infusions of HB-adMSCs over six weeks led to significant reductions in microstructural brain damage, specifically reduced elevated mean diffusivity volumes in the hippocampus, as well as decreased brain immune cell density in key regions as measured by PET imaging. For a neuroscientist focused on developing novel models of chronic pain and placebo analgesia, this work is particularly relevant as it provides strong clinical evidence for a cell-based therapy that can modulate neuroinflammation and improve clinically meaningful outcomes like depression, fatigue, and pain, offering a potential new therapeutic avenue for conditions with overlapping pathological mechanisms.
