Automated Axon Counting in Rodent Optic Nerve Sections with AxonJ

Abstract: We have developed a publicly available tool, AxonJ, which quantifies the axons in optic nerve sections of rodents stained with paraphenylenediamine (PPD). In this study, we compare AxonJ’s performance to human experts on 100x and 40x images of optic nerve sections obtained from multiple strains of mice, including mice with defects relevant to glaucoma. AxonJ produced reliable axon counts with high sensitivity of 0.959 and high precision of 0.907, high repeatability of 0.95 when compared to a gold-standard of m… Show more

“…5 and SI Appendix, Table S5). Our WT C57BL/6 data match those obtained via other automated counting approaches (59,60). Consistent with previous analyses (19), there was no significant difference in the number or density of RGCs in adult Atoh7 KO/+ and SE/+ retinas compared to WT, and KO/KO retinas had scant RGCs.…”

“…www.nature.com/scientificreports www.nature.com/scientificreports/ In our study PPD (paraphenylendiamine) stain was used for histologic preparation. PPD stain has the attribute of labeling the myelin sheath strongly 35 . Therefore we could ensure that primarily axons of interest were stained, allowing these to be counted by both the semi-automated and manual methods, while simultaneously ensuring a strong contrast between the myelin sheath and other structures prior to digital image preparation.…”
