"Because
egl-4 mutants have markedly increased body size in 4-day adults, the number or size of some types of cells is probably increased. We analyzed morphology of four major organs... The volume of whole intestine is increased by 60-80% in the 4-day adult mutants... The volume of hypodermis is increased by approximately 80% in the mutants. In the muscles expressing
myo-3p::gfp (body wall muscles, vulval, uterine and intestine-associated muscles) (Okkema et al., 1993), a great majority of which consists of body wall muscles, the volume increased by 42% or 30% in the mutants."
