Given that the DNA of all cells in one individual is supposed to be the
same, the difference between a labile cell and a committed cell is not a
difference in the DNA. Yet the DNA almost certainly contains both the
information on how to be labile and how to be committed. Given the leanings
of modern cell biology, the difference is probably in the combination of
membrane and cytoplasmic proteins signalling binding proteins that control
gene expression. However, the devil is in the details. Exactly which
proteins and genes is the catch.
