title: Rate of regeneration of sensory axons in transected rat sciatic nerve repaired with epineurial sutures.
abstract: Rat sciatic nerves were cut and the ends were rejoined using epineurial sutures. The most rapidly regenerating sensory axons, as measured by the pinch test, grew at a rate of 3.2 +/- 0.2 (SE) mm/day after a delay of 4.0 +/- 0.3 (SE) days. Regenerating axons began to grow beyond the site of injury about 2 days later in sutured nerves than in crushed nerves; this difference provides an estimate of the scar delay in sutured nerves. The rate of axonal outgrowth was slower in sutured nerves than in crushed nerves throughout the distal stump.
