Electrical polarity in embryos of wild carrot precedes cotyledon differentiation.
Endogenous electrical currents traverse embryos of a higher plant, the wild carrot Daucus carota L. Current enters the apical pole and leaves the region near the presumptive radicle in the radially symmetric globular embryo. Current also enters the exposed surfaces of incipient globular embryos. This electrical polarity precedes differentiation of vascular tissue and cotyledon development. Loca...
متن کاملUnlike in Drosophila Meroistic Ovaries, Hippo Represses Notch in Blattella germanica Panoistic Ovaries, Triggering the Mitosis-Endocycle Switch in the Follicular Cells
During insect oogenesis, the follicular epithelium undergoes both cell proliferation and apoptosis, thus modulating ovarian follicle growth. The Hippo pathway is key in these processes, and has been thoroughly studied in the meroistic ovaries of Drosophila melanogaster. However, nothing is known about the role of the Hippo pathway in primitive panoistic ovaries. This work examines the mRNA expr...
متن کاملCellular polarity in prokaryotic organisms.
Simple visual inspection of bacteria indicated that, at least in some otherwise symmetric cells, structures such as flagella were often seen at a single pole. Because these structures are composed of proteins, it was not clear how to reconcile these observations of morphological asymmetry with the widely held view of bacteria as unstructured "bags of enzymes." However, over the last decade, num...
متن کاملTreatment of Colon Carcinoma Tumors by Electrolysis: Effect of Electrical Dose and Polarity
Introduction: As a physical treatment, electrochemical therapy (ECHT) has provided an effective and useful approach for treating localized tumors. The chemical changes due to a direct electric current destroy the tumor. This study evaluates the effect of electrical dose and polarity on the efficacy of the treatment of a colon tumor model. Materials and Methods: In order to in...
متن کامل08-P012 Cellular polarity in mouse embryonic stem cells during neural differentiation
hypothesis, we used the Cre-loxP system to conditionally inactivate Numb and its homolog Numblike in RPCs at different stages of retinogenesis. We used retroviral vectors expressing Cre recombinase and a reporter to infect Numb/Numblike floxed mouse retinas at early (E13) and late (P0) stages of retinal development. Analysis of cell composition of the resulting knockout clones showed that Numb ...
