Transplanted Human Neurons Restore Damaged Stroke Circuits
Researchers at Sanford Burnham Prebys and Duke-NUS published Jan. 8, 2026 in Cell Stem Cell that human stem-cell–derived neurons transplanted into mice with stroke cavities survived, matured, integrated into existing circuits, and restored function. Using genetic barcodes, single-cell gene expression and machine learning, they identified four neuronal subtypes and transcriptional codes, including Ctip2 effects, that guide axon targeting and enable targeted circuit repair.
Scoring Rationale
Strong peer-reviewed evidence of functional circuit repair in mice; limitation: preclinical results and translation to humans remains unproven.
