Isolation from a naturally occurring cancer. This is the original method for generating an immortalised cell line. A major example is human HeLa, a line derived from cervical cancer cells taken on February 8, 1951 from Henrietta Lacks, a 31-year-old African-American mother of five, who died of cancer on October 4, 1951.

Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) [2] was an African-American woman [5] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line [B] and one of the most important cell lines in medical research. An immortalized cell line reproduces indefinitely under specific ...
Non-human primates are useful as they have a more similar aging pattern to humans compared to rodent models. [60] During non-human primate aging, they can display neuropathy, cognitive changes, and amyloid-β deposits, similar to that of Alzheimer's disease. [60]
However, cellular extensions, in general, can be found on a larger "macro" scale, occupying relatively large areas of the cell membrane. [1] For example, microglia can use their primary processes to constantly monitor and evaluate alterations in the brain environment, and they can further deploy thin filopodia from these primary processes to ...
Astrocytes (green) in the context of neurons (red) in a mouse cortex cell culture 23-week-old fetal brain culture human astrocyte Astrocytes (red-yellow) among neurons (green) in the living cerebral cortex. Astrocytes are a sub-type of glial cells in the central nervous system. They are also known as astrocytic glial cells.
The Alzheimer type II astrocyte is thought to be a pathological type of cell in the brain; however, its exact pathology remains unknown. Like other astrocytes , it is a non-neuronal glial cell . It's mainly seen in diseases that cause increased levels of ammonia ( hyperammonemia ), such as chronic liver disease and Wilson's disease .
HeLa (/ ˈ h iː l ɑː /) is an immortalized cell line used in scientific research. It is the oldest human cell line and one of the most commonly used. [1] [2] HeLa cells are durable and prolific, allowing for extensive applications in scientific study.
Human cells are considered to be a more predictive model and a replacement for other cellular models that serve as proxies, including animal cells, immortalized cell lines, and cadaveric cells. [ 3 ] FCDI offers several terminally differentiated cell types as catalog products: iCell® Cardiomyocytes, iCell Neurons, iCell Endothelial Cells, and ...
