by Elisa Huang, University of Southern California The next time you lose a tooth, could your dentist just grow you a new one? Not yet, but research at USC brings dentists a step closer. Here are a few ways Herman Ostrow School of Dentistry of USC scientists could revolutionize dental care. Tooth Regeneration Rats and mice...

Engineers Create Cross-Linked Hydrogels to Lure Stem Cells Into Wounds
Hydrogels have become a popular material for new treatment strategies targeting a variety of diseases. They can deliver encapsulated therapeutic molecules, degrade in the body at a predefined rate, and can be biocompatible. However, each application requires the hydrogel to have appropriate strength, consistency, and the ability to carry growth factors or other molecules within itself....

Blood stem cells produced in vast quantities in the lab
A glue ingredient was the secret to getting the mouse cellsto multiply outside the body. Researchers have managed to grow large numbers of blood-forming stem cells in the lab using a surprisingly simple ingredient found in glue. And when injected into mice, the cells started producing key components of blood. “The finding is very unexpected and...

Using Antibodies to Detect the Expression of Neural Stem Cell Markers
by Atlas Antibodies Neural Stem Cells Collectively, markers against neural stem cells (NSCs) represent a robust tool in basic research and advanced regenerative medicine. Studies focused on differentiation toward specific neural lineages are supported by changes in the expression levels of specific markers, which can help to identify the presence of neural stem cells. Nestin and SOX2 are two commonly utilized markers for NSCs. Other markers expressed at the cellsurface are ABCG2, FGFR1 and Frizzled-9. NSCs differentiate into...

Researchers release first 3D model of human cell division
Scientists at the Allen Institute for Cell Science have created what they believe is the first comprehensive 3D model for mitosis using human stem cells. Previous models have characterized proteins involved in cell division using abnormal cells, but project co-director Susanne Rafelski says the Integrated Mitotic Stem Cell project — which includes images from some 2,000 mitotic cells and 15 structures within cells — captures how normal cells behave....

Scientists discover self-defense “switch” for stem cells
With the power to turn themselves into any other cell in the body, stem cells have a future as a key treatment for a range of diseases and injuries. The problem is, they lack some of the self-defense mechanisms that other cells have, leaving them open to attack from viruses and other threats. Now, researchers...

Surprising research result: All immature cells can develop into stem cells
by University of Copenhagen A sensational new study conducted at the University of Copenhagen disproves traditional knowledge of stem cell development. The study reveals that the destiny of intestinal cells is not predetermined, but instead determined by the cells’ surroundings. The new knowledge may make it easier to manipulate stem cells for stem cell therapy. The results have been published in Nature. All cells in the foetal gut have...

Pluripotency or differentiation — That is the question
HELMHOLTZ ZENTRUM MÜNCHEN – GERMAN RESEARCH CENTER FOR ENVIRONMENTAL HEALTH Induced pluripotent stem cells can turn into any type of cell in the body or remain in their original form. In the current edition of Molecular Cell, scientists from the Helmholtz Zentrum München describe how cells “decide” which of these two directions to take. During their research, they...

11-Year-Old Autistic Boy Danny Bullen Speaks First Full Sentence Hours After Stem Cell Treatment
An 11-year -old boy with a severe case of autism finds hope with stem cell treatment that allowed him to speak his first sentence. Danny Bullen was diagnosed with autism spectrum disorder in 2010. His condition led to a number of developmental delays including a total loss of verbal ability. Stem Cell For Autism Prior...

Using stem cells to combat osteoarthritis
Published Today By Tim Newman Fact checked by Isabel Godfrey In a recent preliminary study, scientists used stem cells to ease osteoarthritis. Although the trial was small-scale, the results are promising and will pave the way for larger studies. Osteoarthritis of the knee (KOA) occurs when the cartilage — the joint’s natural cushioning system —...
