Figure 3. Atraumatic ETS repair.

A. The fluorescent-naïve median nerve graft, marked by a dashed line, is sutured ETS to the donor common femoral nerve using the sleeve technique and imaged at t=0 days in a mThy1-YFP(16) mouse. B. No axons observed regenerating into the recipient limb at t=60 days in mThy1-YFP(16) mice. C. By 150 days, faint fluorescence is noted in 50% of mThy1-YFP(16) mice. D. In mThy1-GFP(S) mice, all of the grafts remained devoid of fluorescent-labeled axons to 150 days.
