Effect of probiotics or high incubation temperature on gene expression and cell organization of the small intestine and yolk sac of chicks
… organs share a similar structure of epithelial cell-lined villi with tight junctions between adjacent cells. Probiotics have been reported to improve chicken growth performance and gut health including promotion of intestinal morphology. However, there are few studies that show the effect of …

FUNCTIONAL STUDY OF MAMMARY EPITHELIAL CELL ARCHITECTURE
Cell organization confers cellular identity and guides cellular functions. Here, the

Studies on Cell Membrane Ultrastructure, and the use of the Freeze-Fracturing Technique in Electron Microscopy
… appearance of frozen-fractured mouse liver cell membranes, and consistent variations in the distribution of membrane-associated particles caused by various pretreatments as described by previous investigators, were confirmed in this study. 2) Freeze fracturing, was evaluated as a method for …

Geometry and transport in development
… systems ranging from organelles to every single cell within specific tissues or even whole organisms. This enables quantitative physical modeling to understand the phenomena driving and controlling the emergence of spatial patterns and organization in development. In the first half of this …

THE ROLE OF NON-MUSCLE MYOSIN IN TENDON AND ATTACHMENT UNIT FORMATION AND MATURATION
… loads to the nucleus, supporting critical cellular functions such as division, migration, mechanosignaling, and cytoskeletal organization. Given the importance of loading on tendon biology and NM-II’s central role in regulating cytoskeletal tension, we hypothesized that NM-II-mediated …

The Role of Sox17 in Normal and Pathological Beta Cell
… which are also known regulators of postnatal β cell function. Our data shows that Sox17 is expressed in all islet cells. Thus, we hypothesize that Sox17 is a key modulator of β cell homeostasis.</p><p>In the course of this study, we discovered a novel role for Sox17 in regulating insulin …

The Role of PRICKLE1 in the Regulation of Uterine Structure and Physiology
… implantation and pregnancy. The smooth muscle cells of the myometrial layer are organized into several sub-layers with longitudinal and circular orientations and help to facilitate uterine contractions and sperm transport. The specific cellular arrangement and orienertaion is crucial for the …

Cellular and Molecular Mechanisms of Retinal Neuron Spatial Patterning
<p>During development, cell-cell recognition events mediate crucial steps in the formation of organized cellular patterns critical for tissue function. In the nervous system, cell recognition cues guide migrating neurons during development to appropriate terminal locations and sculpt their …

Cell mechanics-based modelling and in toto imaging describe a new mode of lumen formation in chicken neural tube
… through secondary neurulation where the caudal cell mass forms multiple de novo lumens that then merge to form a central lumen. Second neurulation is also thought to be present in several other species, such as mouse and human, whilst zebrafish takes a different approach of lumen opening that …

3D Cell Culture in Microgels: A Novel Screening Platform for Disease Modelling and Drug Testing
… drug candidates are usually tested on 2D cancer cell lines adhered to a plastic surface, which neglect many aspects of a tumour in vivo, such as cell-cell and cellmatrix interactions. In 2011, the first successful long-term culture of epithelial cells from primary tissue was developed by the …

ELUCIDATION OF THE UNIQUE TRANSLATION OF ANGIOGENIC SIGNALING BY AORTIC VALVE CELLS
… However, the process through which native valve cells, valve endothelial cells (VECs) and valve interstitial cells (VICs), form the neovascularization exhibited during CAVD is unclear due to their atypical translation of several angiogenesis related signals. Therefore, the in vitro angiogenic …

Elastic interactions of cellular force patterns
Gewebezellen sammeln ständig Informationen über die mechanischen Eigenschaften ihrer Umgebung, indem sie aktiv an dieser ziehen. Diese Kräfte werden an Zell-Matrix-Kontakten übertragen, die als Mechanosensoren fungieren. Jüngste Experimente mit Zellen auf elastischen Substraten zeigen, dass Zellen …
