Drosophila embryonic hemocytes
population size — seemed to fit well the predictions for purging to occur. But did purging actually take place? In the next step, the authors measured the extent of inbreeding depression in native and invasive species. Beetles from three native and three invasive populations were mated either with their siblings (inbreeding) or with unrelated individuals (outbreeding), and fitness-related trait...
متن کاملDrosophila Embryonic Hemocytes Produce Laminins to Strengthen Migratory Response
The most prominent developmental function attributed to the extracellular matrix (ECM) is cell migration. While cells in culture can produce ECM to migrate, the role of ECM in regulating developmental cell migration is classically viewed as an exogenous matrix presented to the moving cells. In contrast to this view, we show here that Drosophila embryonic hemocytes deposit their own laminins in ...
متن کاملEmbryonic origin of hemocytes and their relationship to cell death in Drosophila.
We have studied the embryonic development of Drosophila hemocytes and their conversion into macrophages. Hemocytes derive exclusively from the mesoderm of the head and disperse along several invariant migratory paths throughout the embryo. The origin of hemocytes from the head mesoderm is further supported by the finding that in Bicaudal D, a mutation that lacks all head structures, and in twis...
متن کاملThe two origins of hemocytes in Drosophila.
As in many other organisms, the blood of Drosophila consists of several types of hemocytes, which originate from the mesoderm. By lineage analyses of transplanted cells, we specified two separate anlagen that give rise to different populations of hemocytes: embryonic hemocytes and lymph gland hemocytes. The anlage of the embryonic hemocytes is restricted to a region within the head mesoderm bet...
متن کاملThe Drosophila VEGF receptor homolog is expressed in hemocytes
Several signalling pathways have been defined by studies of genes originally characterised in Drosophila. However, some mammalian signalling systems have so far escaped discovery in the fly. Here, we describe the identification and characterisation of fly homologs for the mammalian vascular endothelial growth factor/platelet derived growth factor (VEGF/PDGF) and the VEGF receptor. The Drosophil...
