Table 1.

Mean data ± standard deviation (∆σ) of immunopositivity of: RPE, PRL (inner and outer segments), OPL, ACs, BCs, HCs, IPL, and GCs detected by BDNF, NGF, NT-3, TrkA, TrkB, TrkC, and compared with anti-Opsin, anti-Chat, Parvalbumin and, s100p. The statistical analysis shows a different distribution pattern of the antibodies used in this study in cellular layer of N. guentheri retina. Mean values ± standard deviation (Δσ). (ꟷ) No value. Statistical significance: *** p < 0.001, ** p < 0.01, * p < 0.05.
