Discussion

Evaluation of hypoxia-conditioned extracellular vesicles shows significant infarct volume reduction, suggesting potential neuroprotective effects.

HxEV treatment significantly reduced infarct volume from day 1 through day 21, promoting recovery.
MRI with diffusion tensor imaging revealed progressive normalization of fractional anisotropy in treated rats.
Histological analysis confirmed greater dendrite and axon preservation in HxEV-treated animals compared to controls.
Region-specific therapeutic responses were observed, particularly in the corpus callosum related to stroke recovery.

Heras‐Romero et al. (2025) studied this question.
