Evidence class
Published experiment — human-derived cells in vitro
Source access
Wiley full text and figure captions inspected; supplement not independently inspected. Donor count and donor-to-experiment mapping remain unverified.
Model
Adult human bronchial epithelial cell-derived motile spheroids; scratch assays in human neural monolayers.
Donors / population
Count: UNKNOWN . Unknown from inspected material; do not substitute bot counts or experiment counts.
Experimental units
Individual spheroids for morphology/motility; 10 experimental bridge replicates in Figure 6. Five maintained bridging connectivity, and closure was reported beneath all five.
Controls
Native uninjured neural tissue, adjacent/distal scratch regions, and passive agarose loading comparator.
Endpoints
Morphology, ciliary movement, trajectories and neuronal pixel coverage at scratch bridges.
Finding in scope
Adult somatic cells self-organized into motile constructs without direct genetic editing; stable bridges were associated with localized gap closure.
Limitations
In-vitro gap coverage does not establish restoration of a functioning nervous system, clinical repair, or a bioelectric mechanism. Selection of stable bridges matters; donor replication is unresolved.
Next test
Audit donor/batch mapping and blinded gap scoring; distinguish migration, proliferation and survival; add electrophysiological and durable connectivity endpoints before functional neural claims.
Human clinical evidence
None established by this study.
