Novel laboratory technique nudges genes into activity

...e most effective and consistent method to date for coaxing genes into making the proteins that carry out all of life’s functions ?a process formally called gene expression. In any medical specialty, Dr. Janowski said, there are conditions where increased gene expression would prove beneficial. "In so...

MIT device draws cells close -- but not too close -- together

...ible without touching. But on a microscopic level, coaxing cells to be very, very close without actually touching one another has been among the most frustrating challenges for cell biologists. Now MIT researchers led by Sangeeta Bhatia, associate professor of electrical engineering and computer science at ...

How fish mend a broken heart

... fish mends a broken heart may suggest methods for coaxing the damaged hearts of mammals to better heal, researchers report in the November 3, 2006 issue of Cell, published by Cell Press. The researchers found that the hearts of zebrafish harbor progenitor cells that spring into action to restore wounded he...

Biofuel cells without the bio cells

... is the bacterial equivalent of removing lungs and coaxing the disembodied tissue to breathe. Squier and principal authors Yijia Xiong and Liang Shi, PNNL staff scientists, discovered that the proteins, outer membrane c-type cytochrome A, or OmcA, formed a dense coating on the iron-rich mineral hematite. T...

MIT creates 3-D scaffold for growing stem cells

...Center for Biomedical Engineering, is a pioneer in coaxing tiny fragments of amino acids called self-assembling peptides to organize themselves into useful structures. Working with visiting graduate student Fabrizio Gelain from Milan, Zhang created a designer scaffold from a network of protein nanofibers, ea...

Worm hormone discovery may aid fight against parasitic disease

...eping them perpetually in an immature state, or by coaxing them to mature before a food source is available. Other UT Southwestern authors on the paper are lead author Daniel L. Motola, an M.D./Ph.D. student in the Medical Scientist Training Program; Dr. Carolyn Cummins, a research fellow in pharmacology an...

NJIT engineer poised to take stem cell research a step forward

...ns. So I'd like to regenerate that nerve tissue by coaxing stem cells to turn into neurons. My hope is that in five years, say, a person with spinal cord impairment could visit a doctor and be injected with a supply of stem cells. After such treatment, the patient's spinal cord would begin to heal." Wor...

Sperm stem cells closer to being like embryonic stem cells

... sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body. Researchers at the Cecil H. and Ida Green Center for Reproductive Biology Sciences at UT Southwestern Medical Center devised methods to ke...

New complete muscle grown in the lab

...l networks that they provide may also be useful in coaxing the muscle cells to differentiate and organize themselves in a mature, three-dimensional tissue, the researchers suggest. To test the new muscles' therapeutic potential, the researchers implanted them within three groups of living mice. The new musc...

Researchers develop new method for facile identification of proteins in bacterial cells

...elaborate conventional sample preparation steps by coaxing the cells into mass production of the protein the researchers wish to analyze. "Finding a specific target in a mixture of hundreds of proteins can be likened to finding the proverbial needle in the haystack; this task can be performed much faster an...
