Figure 4. The differential growth of regenerating axons within BXD strains. The longest distance that five axons regenerated (A) and the longest regeneration for a single axon (B) are shown for the two control strains (DBA/2J and C57BL/6J untreated mice) and in nine strains treated with the regeneration protocol. Boxplots show median, 25^th and 75^th percentile, maximum, and minimum values for each BXD recombinant inbred strain. Black dots: outliers. *: p<0.05 when compared with BXD102. **: p<0.01 when compared with BXD102.
