Normal human cells, and even cancer cells will (regrettaby) stop dividing after a few generations.

The cells are called HeLa cells, after mrs. Lacks. The cell line is used extensively in biomedical research, testing of among other things drugs and environmental factors, and as a growth medium for viruses (viruses can't proliferate outside cells, and for viruses infecting humans, human cell cultures are especially useful). The Salk vaccine against poliomyelitis was developed using HeLa cells (poliovirus could until HeLa only be grown in human and simian nervous cell cultures). According to Wikipedia almost 11000 patents are connected to HeLa cells.

Since 1951 20 tons of cells have been produced, the number of HeLa cells thus far exceeds the number of cells in Henrietta. Due to ongoing mutations there are now several genetically different lines of HeLa cells.

The use of her cells raises several ethical and privacy questions, most important is the fact that the cells were taken from her without her knowledge and consent. Today the Lacks family is involved in deciding the use of the cell line.

There's a book about her, and being most cynical, this is more or less exploiting a person's genome - without giving her or her family a share of the profits, not even the patents.
It's like Biopiracy 3.0, so to say.
Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius and a lot of courage to move in the opposite direction. (E.F.Schumacher, Economist, Source)
