1. Human umbilical cord–derived mesenchymal stem
cells (hUC-MSCs) can be manipulated via neuronal differentiation and
dedifferentiation in vitro.
2. Compared with naïve hUC-MSCs, dedifferentiated hUC-MSCs reveal distinguished stem cell phenotype such as enhanced cell survival, neuronal differentiation potential, and cell migration.
3. Local administration of hUC-MSCs or dedifferentiated hUC-MSCs significantly improves brain functional recovery in hypoxic-ischaemic encephalopathy rat model.
4. Compared with hUC-MSC, dedifferentiated hUC-MSCs exhibit stronger repair function, as demonstrated by more improved motor, learning, and memory abilities.
5. The enhanced therapeutic effects of dedifferentiated hUC-MSCs are attributed to enhanced neural protection and promotion of endogenous repair.
