Cadherin-Mediated Cell-Cell Interactions Regulates Phenotype And Morphology of Nucleus Pulposus Cells Of The Intervertebral Disc
<p>Juvenile nucleus pulposus (NP) cells of the intervertebral disc (IVD) are large, vacuolated cells that form cell clusters with numerous cell-cell interactions. With maturation and aging, NP cells lose their ability to form these cell clusters, with associated changes in NP cell phenotype, …

Capacity improvements for a direct-sequence code division multiple access network
The rapidly increasing demand for cellular telephony is placing greater demand on the limited bandwidth resources available. This research is concerned with techniques which enhance the capacity of a Direct-Sequence Code-Division-Multiple-Access (DS-CDMA) mobile telephone network. The capacity of …

Role of multicellular organisation in mesoderm differentiation
… important for the differentiation of pluripotent cells in vitro and in vivo? During development, pluripotent cell fate decisions are spatiotemporally coordinated with changing tissue architecture. Typically, changes in tissue architecture are thought to be a downstream consequence of changes in …

Capillary characteristics in microfluidic experiments and computational simulation
… a 3D hybrid, agent-field model where individual cells are modeled as sprout-forming agents in a matrix field. Cell independence, cell-cell communication and stochastic cell response are integral parts of the model. The model simulations incorporate probabilities of an individual cell to …

Production of Compositional Analogues of Bone Based on Electrophoretically Deposited Mineralised Collagen Films
… water, and by moderating the deposition and EPD cell parameters. The impact of citrate ions and hyaluronic acid on the collagen mineralisation process was evaluated using XRD and NMR analysis of the mineralised collagen films. The data obtained revealed a similar composition to the proposed bone …
