    layers of cells covering body surfaces and lining cavities

    Epithelial tissues, also known as epithelia, are layers of cells that cover the surfaces of the body, both inside and out. They form the outer layer of the skin, line the cavities and organs, and are involved in protection, secretion, and absorption. These tissues are crucial for creating barriers and interfaces between different environments, such as the skin protecting against pathogens and the lining of the gut absorbing nutrients.

      Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
