In vivo expression of B-glucuronidase has been associated with inflammation, and inflammatory cells such as lymphocytes, kupffer cells (liver immune cells) and/or macrophages. Glial cells such as astrocytes and oligodendrocytes share a common embryonic origin with neurons; however, these cells can proliferate, especially in response to trauma. Post-mitotic cells don't divide further after they reach maturity. Quiescent cell populations aren't actively progressing through the cell cycle but are still capable of mitosis if stimulated. The sub populations of T cells with functional difference can be identified by means of surface markers (CD markers) or antigens.

Releasing toxins is just collateral damage. Finally, senescent cells damaged by wear and tear don't undergo mitosis. Most cell types divide in very young children as they grow, but in the adult human, there are cells that (1) do not divide, (2) can be forced to divide but usually do not, and (3) cells that are constantly being renewed at various rates… then there are the unique cases of cancer cells and stem cells for example. These include erythrocytes, platelets, neurons, retinal photoreceptors, cardiac cells and skeletal muscle cells. Survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained. Thus, to Barcroft homeostasis was not only organized by the brain—homeostasis served the brain. The cells making up these two body layers are relatively simple.
