Autolysis in Crustacean Tissues after Death: A Case Study Using the Procambarus clarkii Hepatopancreas

Figure 2

The histological changes of hepatopancreases over time after death. (a–c) Normal hepatopancreatic histological appearance. (d–f) The hepatic tubules were swollen, hepatopancreatic stroma widened (), the lumen dilatated (☆), R cell fusion (Δ), and hepatic tubule epithelial cells sloughed from the basement membrane (⟶). (g–i) Large areas of mesenchyme expanded at lower power, necrosis of some epithelial cells (), accumulation of debris in the lumen (☆), R cells fusion, and necrosis (Δ). (j–r) Hepatic tubule epithelial cells sloughed from the basement membrane (⟶); hepatic tubule cell necrosis (☆), and large necrosis areas ().
