Fig. 3From: 3D printing of injury-preconditioned secretome/collagen/heparan sulfate scaffolds for neurological recovery after traumatic brain injury in ratsA Rat mNSS scores were recorded at 1, 3, 7, 14, 21, and 28 days after implantation of differentiated scaffolds after TBI. B Representative motor evoked potential waveforms at 2 months posttransplant in the four groups. C, D The amplitude (C) and latency (D) of MEP in four groups. E Representative swimming paths in the Morris water maze in the four groups. F–H Escape latency (F), time spent in the target quadrant (G), and number of site crossings (H) in the four groups. *P < 0.05, **P < 0.01 versus TBI group, #P < 0.05, ##P < 0.01 versus 3D-CH-ST groupBack to article page
