Endothelium vs Epithelium: Spot the Difference


Illustration of key differences between Endothelium vs Epithelium. Epithelium of epithelial cells refers to a broad group of cells that cover body surfaces (skin), line covering of organs (respiratory system, digestive tract, etc.). These cells are involved in protection, adsorption of fluids, and secretion. In contrast, the endothelium forms a single-cell layer that lines blood and lymphatic vessels. Endothelial cells regulate blood flow, tissue homeostasis, the exchange of electrolytes, and vascular function. While epithelial cells can form multiple layers, endothelial cells are always thin and simple to allow efficient transport.

Illustration of the steps involved in Swine Liver hepatocytes cell isolation.

The schematic representation of sequential processes involved in the isolation of primary hepatocytes from Swine Liver. The liver tissue is collected and perfused to remove blood. The tissues are thoroughly washed, followed by mechanical disintegration and enzymatic digestion. The enzyme used is either collagenase or trypsin, which dissociate the extracellular matrix and release hepatocytes from the tissue structure. The cell suspension is further filtered and centrifuged to isolate a single cell suspension. The cells are seeded in a culture flask/petri dish in a suitable medium (consisting of all macronutrients and micronutrients). The cells are isolated at 37°C in the presence of 5% CO2 and 95% humidity. The cells are observed at specific time intervals. On reaching 80-85% confluency, the cells are subcultured and used for experimentation.

Primary Human Hepatocytes in Regenerative Research

Illustration of human primary cells that have a crucial role in dermatological and regenerative research. It mimics the physiological environment in the human body. Human Dermal Fibroblasts are used in skin regeneration research, wound healing, extracellular matrix production, tissue engineering, and cellular ageing. Primary human hepatocytes serve as the gold standard for investigating liver metabolism, drug toxicity, and liver disease mechanisms. The cells appear in connective tissues (dermis layer). In primary culture cells are isolated from specific human tissue or animal models in controlled laboratory conditions.
