Hi, and sorry for my English. I have a problem understanging the following article http://www.chirurgiewien.at/wp/wp-co...e-EJC-2008.pdf
In this article, 8 cell strains derived from patients with medullary thyroid carcinoma are used.
All strains except one have a low telomerase activity, their telomeres shortened each time they replicate, and then they stop dividing after a certain number of division. Only in rare cases spontaneous immortalised cells arise when the experiment is conducted several times.
I really don't understand that. If thoses cells are mortal, they aren't cancer cells no ?
Have a nice day
