Bioartificial kidney under study at MCG

...profit organization that provides researchers with tissues and organs anatomically unsuitable for transplant. The cells are grown into the walls of thousands of hollow fibers contained in a cartridge similar to those used for traditional dialysis. With dialysis, a patient's blood runs through the fibers an...

Wisconsin scientists grow critical nerve cells

...p into any of the 220 different types of cells and tissues in the body. But researchers have struggled to convert blank-slate embryonic stem cells into motor neurons, says Zhang. The goal proved elusive even in simpler vertebrates such as mice, whose embryonic stem cells have been available to scientists fo...

University of Manchester makes made-to-measure skin and bones a reality using inkjet printers

The transparent organism: EMBLEM and Carl Zeiss give labs a unique look at life

... which prevented scientists from looking deep into tissues in the past. The entire procedure is very fast and in a computer supported post-processing step, one or more stacks of images are assembled into a high-resolution film. Another advantage of SPIM is that the specimen is kept alive in a liquid-filled ...

Molecular machine may lead to new drugs to combat human diseases

..., a form of pneumonia, and thrush, an infection of tissues in the oral cavity. This makes introns a potential target for therapeutics against these diseases by using a strategy called targeted trans-splicing in which introns are manipulated to cut out malfunctioning genes. Introns' unique capability of cutt...

Scientists rid stem cell culture of key animal cells

...c stem cells are capable of forming any of the 220 tissues and cells in the human body and, in culture, are constantly trying to migrate down different developmental pathways. Maintaining stock cultures in their undifferentiated state is critical. The feeder cell dogma now can be overturned, says lead inves...

ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors

...ch free radicals and potentially protect cells and tissues in the body from oxidative damage. Now, McGraw says, he's interested in learning more about the connection between the red colors and anti-oxidants within and among parrot species, as well as "to specifically explore the balance of naturally and sex...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...recisely, we do not know how that happens or which tissues and cells are involved. Once we're equipped with a better knowledge of the insect breathing pattern it could shed light on when pesticides should be used to control insects -- crucial for the agricultural industry." ...

NC State scientist finds soft tissue in T. rex bones

...at when dinosaurs died and became fossilized, soft tissues didn't preserve ?the bones were essentially transformed into "rocks" through a gradual replacement of all organic material by minerals. New research by a North Carolina State University paleontologist, however, could literally turn that theory inside...

NJIT Presidential Award winner takes stem cell research another step

...an undifferentiated cell that builds and maintains tissues and organs, and which can renew itself through cell division. Stem cells are harvested from bone marrow, umbilical cords, the brain and spinal cord and other tissues. Adult stem cells also have a unique trait that lends them their magic: Under the ri...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...e expression in real-time. Because MRI images deep tissues non-invasively and at high resolution, investigators don't need to sacrifice animals and perform laborious and costly analysis. To trigger living cells into producing their own contrast agent, Ahrens gave them a gene that produces a form of ferritin...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

Haynes, an AIDS researcher who has also studied autoimmune diseases, began to focus on possible similarities between HIV infection and the biology of autoimmunity after work on an experi...

Antibiotic might fight HIV-induced neurological problems

...ive impairment." SIV and HIV both affect the same tissues in the same way and use the same tricks to infect cells and outwit treatments, but SIV infects only non-human primates, and HIV only infects people. Antiretroviral drugs target and interfere with the viral proteins needed to accomplish this. In cont...

Potential treatments for neurofibromatosis

...signals that cause the mast cells to congregate in tissues surrounding the tumors. The mast cells create chemicals called growth factors that enable the creation of blood vessels. The IU investigators now are identifying drugs that can disrupt the function of mast cells and their proteins in ways that they ...

Hirsute Or Hairless? Two Proteins May Spell The Difference

...undamental processes that generate a wide range of tissues and organs, including the lungs, cornea, and mammary glands. How complex, three-dimensional structures emerge from single sheets of cells is a fundamental question in developmental biology. The dispensability of hair follicles makes them the perfect...
