Immortalized Cell Lines

At first glance immortalized cell lines and maintaining them seem to be a sort of necessary evil of lab.  More of a tool to get work done than anything.  A protocol which until recently I haven't honestly put too much thought into.  I've known what goes into them and the purpose of different substances, but my thought on them plateaued in a sense.  However I've found that the more time I spent splitting the cell lines I've been maintaining, the more I think about what goes on beyond the normal routine of the protocol of splitting them.

At times I've wondered how these cell lines were produced. Why are they not cancerous? Could they be cancerous because they are indefinitely proliferating?

Is immortalization possible with other cell lines? Can stem cells be give rise to other stems? Can you clone pluripotent stem cells?

Is it possible that cells in vitro could evolve differently than in vivo cells?

Last but not least, my most "out there" idea. Would it be possible to reassemble life in space? Is the fusion of sex cells on an unmanned spacecraft possible to extend the length of interstellar voyages. How do cells react in zero gravity.

So many questions...

Beware...

Some of you might hear the myth about a little girl running around the lab at night...  but that is just a myth.

On the other hand, I encounter paranormal activity in our own lab. We called it THE centrifuge. It is a mentally deranged scientist from the 1920's who had an obsession for the power of a centrifuge. The story tells that he likes to grab as many tubes as possible and walk the halls of the lab trying to mix the solution until he forms a pellet. 

And, I happen to record him in action... take a look, but BEWARE! you might be scared...
