	Dirunal hormone cycles are acknowledged to be important in ageing
of intact animals, but when "in vitro" cell doubling limits are discussed
the standard model is steady state medium composition.  Does anyone out
there know of any studies where the tissue culture media has been regulated
to mimic the normal "in vivo" hormonal pattern?
