Stem cells and tissue-specific cells can be grown in abundance from mature mammalian cells simply by blocking a certain membrane protein, according to scientists at the University of Pittsburgh School of Medicine and the National Institutes of Health (NIH). Their experiments, reported today in Scientific Reports, also show that the process doesn't require other kinds of cells or agents to artificially support cell growth and doesn't activate cancer genes. Scientists hope that lab-grown...

Understanding the molecular control of placenta formation, the organ which enables fetal growth, is critical in diagnosing and treating related pregnancy complications. A group of scientists at the Chinese Academy of Sciences, Beijing, China, and the University of Calgary, Canada has revealed a molecular feedback loop that governs the earliest steps of placenta formation in mice, which is known to mimic placenta formation in humans. Their findings are published April 16 in the open access...

CWRU research developing technique with promise to guide formation of complex tissues Stem cells can be coaxed to grow into new bone or new cartilage better and faster when given the right molecular cues and room inside a water-loving gel, researchers at Case Western Reserve University show. By creating a three-dimensional checkerboard–one with alternating highly connected and less connected spaces within the hydrogel–the team found adjusting the size of the micropattern...

When it comes to delivering genes to living human tissue, the odds of success come down the molecule. The entire therapy – including the tools used to bring new genetic material into a cell – must have predictable effects. Now, a new screening process will simplify non-viral transfection, providing a method researchers and clinicians use to find an optimal set of biomaterials to deliver genes to cells. Developed by William Murphy, the Harvey D. Spangler professor of...

Hardening of the arteries, or atherosclerosis, is the primary cause of heart disease. It is caused by calcium accumulation in the blood vessels, which leads to arteries becoming narrow and stiff, obstructing blood flow and leading to heart complications. Although many risk factors for atherosclerosis have been identified, the cause is not known and there is currently no way to reverse it once it sets in. In a new study published 9th April in the open access journal PLOS Biology, researchers...

Adhesive Force Differences Allows Separation Of Stem Cells To Advance Therapies
2013-04-08 11:28:26

Georgia Institute of Technology A new separation process that depends on an easily-distinguished physical difference in adhesive forces among cells could help expand production of stem cells generated through cell reprogramming. By facilitating new research, the separation process could also lead to improvements in the reprogramming technique itself and help scientists model certain disease processes. The reprogramming technique allows a small percentage of cells — often taken...

Cells in the body need to be acutely aware of their surroundings. A signal from one direction may cause a cell to react in a very different way than if it had come from another direction. Unfortunately for researchers, such vital directional cues are lost when cells are removed from their natural environment to grow in an artificial broth of nutrients and growth factors. Now, researchers at the Stanford University School of Medicine and the Howard Hughes Medical Institute have devised a...


Word of the Day
omadhaun
  • 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.
