Whole-cell chloride currents in rat astrocytes accompany changes in cell morphology.
Astrocytes can change shape dramatically in response to increased physiological and pathological demands, yet the functional consequences of morphological change are unknown. We report the expression of Cl- currents after manipulations that alter astrocyte morphology. Whole-cell Cl- currents were elicited after (1) rounding up cells by brief exposure to trypsin; (2) converting cells from a flat...
متن کاملTransient genetic asymmetry and cell fate in a bacterium.
Certain species of Gram-positive bacteria can initiate a developmental program that results in the formation of two daughter cells with different fates. One cell develops into a spore and the other cell undergoes programmed lysis, with each process being mediated by a cascade of cell-type-specific transcription factors. An early and critical step in this developmental pathway is the formation o...

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Dynamic and Polarized Muscle Cell Behaviors Accompany Tail Morphogenesis in the Ascidian Ciona intestinalis
BACKGROUND Axial elongation is a key morphogenetic process that serves to shape developing organisms. Tail extension in the ascidian larva represents a striking example of this process, wherein paraxially positioned muscle cells undergo elongation and differentiation independent of the segmentation process that characterizes the formation of paraxial mesoderm in vertebrates. Investigating the c...
متن کاملElectrophysiological changes that accompany reactive gliosis in vitro.
An in vitro injury model was used to examine the electrophysiological changes that accompany reactive gliosis. Mechanical scarring of confluent spinal cord astrocytes led to a threefold increase in the proliferation of scar-associated astrocytes, as judged by bromodeoxyuridine (BrdU) labeling. Whole-cell patch-clamp recordings demonstrated that current profiles differed absolutely between nonpr...
