The embryonic origin of imaginal discs in Drosophila.
نویسندگان
چکیده
The thoracic imaginal discs of Drosophila melanogaster can be observed during embryogenesis as clusters of cells with particular shapes, sizes and behaviours. These structures can be detected soon after germ band shortening and their development appears to be tightly linked to that of the larval epidermis.

The Preparative Isolation of Imaginal Discs from Larvae of Drosophila Melanogaster
Imaginal discs of insccts have long been known to be embryonic Anlagen (1). Indeed, in Drosophila, the external structures in the head and thoracic regions, as well as some in the abdominal region, develop from imaginal discs (2). Discs develop normally when transplanted into larvae, and Schneider (3) has recently shown that eye discs develop normally and become pigmented in a defined medium. T...
متن کاملWe have analyzed the cell lineage of larval and imaginal cells in the thoracic ectoderm of the early embryo of Drosophila melanogaster, by homotopic transplantation
In holometabolous development, higher insects pass through two stages, the larva and the imago. Both larval and imaginal cells are derived from the cells of the blastoderm stage. After the final embryonic wave of mitosis, however, only the imaginal cells remain diploid and capable of division, proliferate massively and do not differentiate. The development of the imaginal discs in Dacus tryoni ...
متن کاملDissection and immunostaining of imaginal discs from Drosophila melanogaster.
A significant portion of post-embryonic development in the fruit fly, Drosophila melanogaster, takes place within a set of sac-like structures called imaginal discs. These discs give rise to a high percentage of adult structures that are found within the adult fly. Here we describe a protocol that has been optimized to recover these discs and prepare them for analysis with antibodies, transcrip...
متن کاملTranscription of the segment-polarity gene wingless in the imaginal discs of Drosophila, and the phenotype of a pupal-lethal wg mutation.
Wingless (wg) is a segment-polarity gene in Drosophila which is related to the murine proto-oncogene int1. In Drosophila embryos, wg transcription defines part of each parasegment. In situ hybridization shows that wg is also expressed in the imaginal discs which give rise to the adult during metamorphosis. Transcripts are localized in the apical cytoplasm of disc cells, and accumulate in differ...
متن کاملCell affinities in antennal homoeotic mutants of Drosophila melanogaster.
DISSOCIATED embryonic cells show, in culture, cell affinities and morphogenetic movements which are tissue characteristic. While cells which derive from the same organ and tissue are able to reconstitute the original cell arrangements in mosaic fashion, cells from different organs sort out and regroup separately. This situation holds for vertebrate cells as well as for cells of many other lower...
