Draper Laboratory is designing a microdevice that will provide a more biologically realistic growth environment for human kidney cells in the laboratory. The proof-of-concept "kidney-on-a-chip" could one day give scientists a more accurate platform for drug screening or disease modeling. Cambridge, MA (PRWEB) June 28, 2012 Researchers designed a microdevice that will better simulate a biologically realistic growth environment for human kidney cells in the laboratory. The proof-of-concept...

The blood-brain barrier is essential for maintaining the brain's stable environment–preventing entry of harmful viruses and bacteria and isolating the brain's specific hormonal and neurotransmitter activity from that in the rest of the body. In addition to nerve cells, the brain contains glia cells that support and protect the neurons. In the fruit fly, the blood-brain boundary is made by glia joined into an envelope sealed around the nerve cells. As the brain rapidly expands during...

By Rickard, Alice Dorokhov, Nikolay; Ryerse, Jan; Klumpp, David J; McHowat, Jane Abstract Tight junctions (TJs) are essential for normal function of epithelia, restricting paracellular diffusion and contributing to the maintenance of cell surface polarity. Superficial cells of the urothelium develop TJs, the basis for the paracellular permeability barrier of the bladder against diffusion of urinary solutes. Focusing on the superficial cell layer of stratified cell cultures of an...


Word of the Day

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
