According to Joseph Panno, Ph.D. book, STEM CELL RESEARCH: Medical Application & Ethical Controversy, ISBN: 0-8160-6601-9, page 5
Embryonic Stem Cells
("The ultimate stem cell is the fertilized egg ... being totipotent, can give rise to an entire organism ....
Mammalian ES cells ... inner cell mass (ICM) of a blastocyst ... ... cannot develop into a embryo. .... In culture, ES cells are immortal, proliferating indefinitely while retaining an embryonic phenotype.")

The answer is Yes!

All cells which come from the human body have a life expectancy... Eventually they will die out through metabolic processes and autolysis. Stem cells for this reason are frozen. However I think that if you provide the correct nurtional and atmospheric conditions you may be able to maintain the life of the stem cells.(keepem livin for longer).
Cells which can be kept indefinately are hybridoma's, normal human cells which are fused together with cancer cells.
Cancer cells have developed the 'immortality' and keep dividing.

Many stem cells are capable of perpetual growth in vitro - so yes, most can be cultured indefinitely.
Stem cells, like germ-line cells (and many cancers) have active telomerase, which allows them to escape the Hayflick limit, and to continue to divide without losing any genetic information.

Yes. That is how the scientists maintain the culture.
