Eye-antennal discs and cephalic complexes obtained from mature third-instar larvae of D. melanogaster were cultured in vitro in synthetic media, in order to investigate the tryptophan metabolism in the eye discs. Eye-antennal discs cultured together with cephalic complexes showed more pronounced growth than discs cultured alone. This indicates that the metamorphic hormone is the most essential substance for growth, differentiation, and pigmentation in the tissue culture of eye discs.
