No stem-cell therapy for long COVID has FDA approval. IND protocols permit investigational trials at US academic centres (Stanford, Yale, UCLA). European trials operate under national regulatory frameworks (EMA compassionate-use pathways available in some countries). Regulatory clarity is evolving as long-COVID natural history becomes better characterised.
Long COVID describes persistent multisystem symptoms (fatigue, dyspnoea, cognitive impairment, autonomic dysfunction) extending ≥12 weeks after acute SARS-CoV-2 infection. Proposed mechanisms include persistent viral fragments in reservoir tissues, endothelial activation with microclot formation, dysregulated immune memory (skewed Th1/Th17 responses, reduced regulatory T cells), and mitochondrial dysfunction. Placental mesenchymal stem cells and exosomes address these pathways through endothelial repair, anti-inflammatory cytokine secretion, and metabolic rescue of dysfunctional immune cells. Eleven registered clinical trials and two actively recruiting protocols evaluate MSC and exosome infusions in long-COVID cohorts, predominantly focusing on severe functional impairment or cardiopulmonary involvement.
