Variable cell number
in nematodes
Studies of the nematode worm Caenorhab-
ditis elegans have led to the widely held belief
that individuals of a given nematode species
are characterized by a property known as
eutely, in which all individuals have the
same total number of cells1
. This property,
which is peculiar to nematodes and a few
other phyla, has raised the question of
whether the developmental mechanisms of
nematodes differ from those of larger meta-
zoans. Here we show that many, perhaps
most, nematode species are not eutelic in at
least one organ, the epidermis, and that in
this respect they resemble other model
organisms such as fruitflies and mice.
