Figure 5. Relationship between PGP9.5-positive NFs (green) and ICs (red) in rumen CM with age. 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 of PGP9.5 positive NFs (B) and ICs (C) in the CM with age, both of them decreased. (Bar = 20 μm in A a–i).
