Developmental regulation of glial cell phagocytic function during Drosophila embryogenesis

Developmental regulation of DNA-topoisomerases during Drosophila embryogenesis.

Type I and type II DNA-topoisomerases are essential enzymes that mediate replication, transcription, recombination, and mitosis in multicellular eukaryotes but the extent of their interchange for specific reactions in vivo is controversial. Expression patterns for topoisomerase I and topoisomerase II during the embryogenesis of Drosophila melanogaster were compared with patterns of DNA replicat...

Glial interactions with neurons during Drosophila embryogenesis.

A monoclonal antibody (Mab5B12) demonstrating specificity for glial cells within the central and peripheral nervous systems of Drosophila has been used in combination with neural-specific antibodies to study the early organization of the Drosophila embryo. The embryonic central nervous system of Drosophila contains cells within the ventral midline that are recognized by monoclonal antibody 5B12...

Expression profiling of glial genes during Drosophila embryogenesis.

In the central nervous system of Drosophila, the induction of the glial cell fate is dependent on the transcription factor glial cells missing (gcm). Though a considerable number of other genes have been shown to be expressed in all or in subsets of glial cells, the course of glial cell differentiation and subtype specification is only poorly understood. This prompted us to design a whole genom...

Programmed cell death during Drosophila embryogenesis.

The deliberate and orderly removal of cells by programmed cell death is a common phenomenon during the development of metazoan animals. We have examined the distribution and ultrastructural appearance of cell deaths that occur during embryogenesis in Drosophila melanogaster. A large number of cells die during embryonic development in Drosophila. These cells display ultrastructural features that...
