Figure 6. Relationship between PGP9.5-positive NFs (green) and ICs (red) in the LM in 5-day (A a–c), 40-day (A d–f) and 70-day (A g–i) groups, respectively. Higher magnification views of the square frames in (A–c,f,g). The cytoplasm and protuberances of the ICs were wrapped by the varicosities with PGP9.5. The MOD change of PGP9.5 positive NFs (B) and ICs (C) in the LM with age, both of them decreased. (Bar = 20μm in A a–i).
