How skin begins: New research could improve skin grafts, and more

University of Colorado Boulder researchers have discovered a key mechanism by which skin begins to develop in embryos, shedding light on the genetic roots of birth defects like cleft palate and paving the way for development of more functional skin grafts for burn victims.

Flipped cells cause blood vessels to leak in diabetes and other diseases

An enzyme activated in diabetics has been found to cause previously aligned cells in a blood vessel to reverse their orientation, creating misalignments that allow veins and arteries to leak three times more blood proteins than normally constructed blood vessels. Controlling the enzyme could ease symptoms of swelling, nerve pain, localized low blood pressure, and risk of infection in diabetes, other diseases that cause blood vessels to leak, and smoking.

Cancer stem cells use normal genes in abnormal ways

CDK1 is a "normal" protein—its presence drives cells through the cycle of replication. And MHC Class I molecules are "normal" as well—they present bits of proteins on the surfaces of cells for examination by the immune system.

Newly identified structure in lymph nodes was hiding in plain sight

In a study published this week in Nature Communications, scientists at Australias Garvan Institute of Medical Research have identified where the immune system remembers past infections and vaccinations—and where immune cells gather to mount a rapid response against an infection the body has seen before.

Virtual tumour new way to see cancer

Scientists in Cambridge have built a virtual reality (VR) 3D model of cancer, providing a new way to look at the disease.

New method grows brain cells from stem cells quickly and efficiently

Researchers at Lund University in Sweden have developed a faster method to generate functional astrocytes from embryonic stem cells. Astrocytes play a significant role in neurodegenerative diseases. The new method reduces the time required to produce the cells from months to two weeks, and the study has been published in Nature Methods.

‘Retina in a dish’ provides new insight into inherited blindness

The inherited eye disease retinitis pigmentosa (RP) is caused by genetic changes that are not well understood. For example, mutations in cell proteins known as “splicing factors” can cause RP, though the exact mechanism behind the problem has been somewhat of a mystery.
