Increased functional recovery in Col HA Lam hydrogel with NPCs group over other groups.

(a) Vibrissae-Elicited Forelimb Placing Test. This test examined the animals sensory-motor function unrelated to reflex by examining a motor task in response to a sensory stimulus unrelated to the direct spinal reflex path. Contralesional limbs and laminectomy control group consistently received a score of 4. b) Cylinder Paw Preference Test. Assessment of forelimb function with the cylinder paw preference test reveals an animal’s ability to use their paws in a normal motion task. The hydrogel with NPCs group improved significantly over the media alone group by six weeks after injury. Laminectomy control group consistently received a score of 49 ± 0.64% for the ipsilesional limb. Note: *p ≤ 0.05, **p ≤ 0.01 (c) Pasta Handling Test. Assessment of time to use the ipsilesional limb after injury reveals the speed of recovery for each experimental group, animals in Col HA Lam with NPCs group began using their ipsilesional paw significantly earlier than the Col HA Lam group.
