Chinese fire-bellied newt histology pigment cell hepatocyte seasonal variation
The pigmentation in the liver of Chinese fire-bellied newt (Cynops orientalis) was described during two periods of the annual cycle (summer activity and winter hibernation). A large number of melanin granules were gathered into clusters and distributed unevenly inside the pigment cells. Liver pigmentation (melanin content) was found unstable, varying during the annual cycle. During the hibernation period, pigmentation accumulation was shown to increase in the liver of the Chinese fire-bellied newt. Hepatocytes during the active period are approximately 14.64% larger than those in the hibernation period, while the nucleus is approximately 7.43% bigger during the active period when compared with that during the hibernation period. These findings indicate that variation in pigment distribution and hepatocyte morphology in Chinese fire-bellied newt liver may be an ecologically adaptive strategy to the adverse physiological conditions during hibernation.
