Fig. 7

Frequency distribution of “g” ratio and dot plot of “g” ratio/axon diameter in the experimental groups. a–d Values were obtained 8 weeks after the lesion in the experimental groups. e–h Values were obtained 12 weeks after the lesion in the experimental groups. Note the shift towards an increase in diameter of the myelinated axon in the autograft and PCL + MSC groups when compared to the PCL group after 8 and 12 weeks
