"1)"Immortal Cells" Don't Need Food to live. (simple) "
Yes, they do. That's why they have to be grown in nutrient broth in order to keep the cell line alive.
"2) Cancer cells are Primitive, and have no function. Except to consume. They are parasites That consume the host. And then Die. (agian simple)"
Cancer cells are actuall normal cells, could be muscle, neural, cardiac, etc, that has become stuck in the growth phase of the cell cycle. This can be
due to oncogenes being turned on by chemicals, certain viruses, etc.
"3) In evolution. Cells that adapt, Evolve."
Umm..I'm not clear on what you're saying here. Yes, that's true, they do, but cancer cells can do the same. When you put a culture of HeLa cells in
a broth rich in arabinose instead of glucose, certain adaptive genes turn on that allow it to metabolise arabinose instead. That counts as
"For some reason, Our own cells Program themselves to die after so many replications. During those replications, The "learned" knowledge of the
previous Cell is passed on. For exp. The Bodies ability to recognize and destroy different Bacteria"
That's not entirely true. First, yes, they are programmed to die for many reasons, including the last replication. This is called apoptosis. However,
they do not pass on "learned" knowledge. The reason cells can recognize bacteria better the second time we get an illness is because during the
first infection, called a first set reaction in immunological terms, we develop plasma B cells and memory B cells (in the case of viruses, we develop
memory T and cytotoxic T cells). The plasma cells release antibodies specific for that bacteria, and then die off about 10 days later. The memory B
cells, however, stick around for about 10 months and then die off. These memory B cells allow us to react to the same infection faster the second time
because they rapidly divide into antibody producing cells quickly, as opposed to the original B cell it derived from. So really, when a cell divides,
it passes on NO "learned" knowledge whatsoever. The adaptive immune system is relient on cellular selection, not evolution.
"Cancer Cells are like the Human Version of the Zombie. They Consume, They are long lasting, But they have no ability to evolve past thier primal
instinct. To Eat. And when All the Human's Are Dead. They die as well. Hardly seems immortal to me."
I think this is where you and I are misunderstanding each other. Immortal cells are not referring to cancer cells in the body. They are referring to
cells grown in a laboratory culture DERIVED from cells in the body. No, of course cancer cells in the body aren't immortal. And it is true they die
when the person dies. Cells in a culture, however, that have been induced to become cancers, can in fact be immortal if given proper nutrients.
