Fig. 4From: Infarct-preconditioning exosomes of umbilical cord mesenchymal stem cells promoted vascular remodeling and neurological recovery after stroke in ratsInfarct-preconditioned exosomes improved spatial learning and memory ability after stroke. The rats were trained to remember the hidden platform in the maze from 3 to 6 days after MCAO. A Representative routes of each group. B The latency was recorded. C The time stayed in the target quadrant of each group. D The number of platform crossings of each group. E Swimming speed of each group. *P < 0.05, **P < 0.01 versus MCAO group and EXO group. n = 10 in each groupBack to article page
