However, because neointimal formation is only observed in patients with pulmo...

spinal cord injury (sci) in humans remains a devastating and incurable disorder. a very important obstacle in axonal regeneration after spinal cord injury is astroglial scaring. the use of self-assembling peptide nanofiber, a hydrogel mimicking extracellular matrix, has been suggested as a scaffold for spinal cord regeneration and inhibition of astrogliosis. however, neurogenesis potential of l...
