Directed 3D cell alignment and elongation in microengineered hydrogels.
Organized cellular alignment is critical to controlling tissue microarchitecture and biological function. Although a multitude of techniques have been described to control cellular alignment in 2D, recapitulating the cellular alignment of highly organized native tissues in 3D engineered tissues remains a challenge. While cellular alignment in engineered tissues can be induced through the use of...
متن کاملAberrant cell expansion in the elongation mutants of barley.
The elongation (elo) mutants of barley (Hordeum vulgare cv 'Himalaya') are a class of dwarf plants with defects affecting cell expansion. The phenotypes of mutants in three of the elo loci (elo1, elo2 and elo3) are recessive to the wild-type allele, and the mutations at elo-4 and elo-5 are semi-dominant. Allelism tests showed that elo1, elo2 and elo3 were at separate loci, and mapping data indi...
متن کاملCorrelation of cutaneous tension distribution and tissue oxygenation with acute external tissue expansion
Today, the biomechanical fundamentals of skin expansion are based on viscoelastic models of the skin. Although many studies have been conducted in vitro, analyses performed in vivo are rare. Here, we present in vivo measurements of the expansion at the skin surface as well as measurement of the corresponding intracutaneous oxygen partial pressure. In our study the average skin stretching was 24...
متن کاملCollective ontology alignment
Enterprises are captivated by the promise of using big data to develop new products and services that provide new insights into their customers and businesses. However, there are significant challenges leveraging data across heterogeneous data stores, including making those data accessible and usable by non-experts. We designed a novel system called Helix which employs a combination of userdriv...
متن کاملCell Chirality Induces Collective Cell Migration in Epithelial Sheets.
During early development, epithelial cells form a monolayer sheet and migrate in a uniform direction. Here, we address how this collective migration can occur without breaking the cell-to-cell attachments. Repeated contraction and expansion of the cell-to-cell interfaces enables the cells to rearrange their positions autonomously within the sheet. We show that when the interface tension is stre...
