Feb 5, 2014 - Recent interest in the neural bases of spatial navigation stems from the discovery of neuronal populations with strong, specific spatial signals. The regular firing field arrays of medial entorhinal grid cells suggest that they may provide place

Oct 28, 2019 - Sea stars use adhesive secretions to attach their numerous tube feet strongly and temporarily to diverse surfaces. After detachment of the tube feet, the adhesive material stays bound to the substrate as so-called ‘footprints’. In the common sea

Oct 31, 2019 - The intestine is the most anisotropically shaped organ, but, when grown in culture, embryonic intestinal stem cells form star- or sphere-shaped organoids. Here, we present evidence that spontaneous tonic and phasic contractions of the circular

Sep 6, 1984 - Early biosynthetic studies implicated the intestine as one of the major sites of synthesis of C1q in guinea-pigs, humans and pigs (Colten et al. 1966; Colten et al. 1968; Day et al. 1970). Columnar epithelial cells were considered to be the

Mar 12, 1990 - For granulocytic-macrophage progenitor populations and their progeny, five glycoproteins have been identified: GM-CSF, G-CSF, multi-CSF, M-CSF and IL-6 that can regulate their proliferative activity, maturation and functional activities. The same

Feb 6, 2014 - Controlling and improving neuronal cell migration and neurite outgrowth are critical elements of tissue engineering applications and development of artificial neuronal interfaces. To this end, a promising approach exploits nano/microstructured

Jun 24, 1980 - Cancers are clones of abnormal cells, arising presumably as the result of mutational or epigenetic alterations of gene expression. The kinetics of appearance of spontaneous cancers in populations of multiplying cells (i. e. the relation between age

Jul 10, 2019 - Hybrid male sterility (HMS) contributes to speciation by restricting gene flow between related taxa. Detailed cytological characterization of reproductive organs in hybrid males is important for identifying phenotypes that can help guide searches of

Jun 6, 2013 - Intravital microscopy has become increasingly popular over the past few decades because it provides high-resolution and real-time information about complex biological processes. Technological advances that allow deeper penetration in live tissues,
