Magnesium deficiency in embryos of Xenopus laevis.
Embryos of Xenopus laevis reared in media with various low (less than or equal to 10(-5) M) magnesium ion concentrations will exhibit differing degrees of a potentially lethal magnesium starvation syndrome depending on the ion concentration and rearing temperature. The higher the rearing temperature or the lower the magnesium ion content of the medium the more severely the syndrome will be expr...
متن کاملFacial transplants in Xenopus laevis embryos.
Craniofacial birth defects occur in 1 out of every 700 live births, but etiology is rarely known due to limited understanding of craniofacial development. To identify where signaling pathways and tissues act during patterning of the developing face, a 'face transplant' technique has been developed in embryos of the frog Xenopus laevis. A region of presumptive facial tissue (the "Extreme Anterio...
متن کاملRegional differences in catheptic activity in Xenopus laevis embryos.
T H A T the intracellular proteolytic enzymes known collectively as 'cathepsins' may have a special function in newly forming tissues was first suggested by the findings of Orechowitsch, Bromley, & Kusmina (1935). These authors observed that in certain amphibians regenerating tail-tissue had a much higher catheptic activity than the normal, non-regenerating tail. Their findings have been confir...
متن کاملThe establishment of polarized membrane traffic in Xenopus laevis embryos
Delineation of apical and basolateral membrane domains is a critical step in the epithelialization of the outer layer of cells in the embryo. We have examined the initiation of polarized membrane traffic in Xenopus and show that membrane traffic is not polarized in oocytes but polarized membrane domains appear at first cleavage. The following proteins encoded by injected RNA transcripts were us...
متن کاملImaging the cytoskeleton in live Xenopus laevis embryos.
Historically, much of our understanding of actin filaments, microtubules and intermediate filaments has come from the study of fixed cells and tissues. But the cytoskeleton is inherently dynamic, and so developing the means to image it in living cells has proved crucial. Advances in confocal microscopy and fluorescent protein technologies have allowed us to dynamically image the cytoskeleton at...
