Recovery of Peripheral Nerve with Massive Loss Defect by Tissue Engineered Guiding Regenerative Gel

Table 1

Number of rats	Treatment of the segmental 15 mm loss*	Experimental length in time
8	Control operated and further implanted with autogenous peripheral nerve graft	90 days
8	Bridged with standard tube only	90 days
8	Bridged with standard tube and filled with gel vehicle including HA only	90 days
8	Bridged with standard tube filled with GRG	90 days

∗In rats model, regeneration within empty tube is possible when gap is up to 7 mm long.
