Figure 2: Longitudinal morphometric data showing myelinated and unmyelinated fiber numbers. Note increasing deficits in both myelinated and unmyelinated fibers in diabetic rats compared to age-matched control rats. However the absolute fiber numbers in diabetic rats did not change over the observation period, suggesting a component of impaired fiber maturation in diabetic animals. * , ** , *** versus age-matched control values.
