Stem cell breakthrough could set up future transplant therapies
A new method for creating stem cells for the human liver and pancreas, which could enable both cell types to be grown in sufficient quantities for clinical use, has been developed by scientists. Using the technique, researchers have for the first time been able to grow a pure, self-renewing population of stem cells specific to the human foregut, the upper section of the human digestive system. These so-called "Foregut stem cells" could then be developed further to produce liver or pancreatic...

How an RNA gene silences a whole chromosome
Researchers at Caltech have discovered how an abundant class of RNA genes, called long non-coding RNAs (lncRNAs, pronounced link RNAs) can regulate key genes. By studying an important lncRNA, called Xist, the scientists identified how this RNA gathers a group of proteins and ultimately prevents women from having an extra functional X-chromosome--a condition in female embryos that leads to death in early development. These findings mark the first time that researchers have uncovered the detailed...

Discovery of an embryonic switch for cancer stem cell generation
An international team of scientists, headed by researchers at UC San Diego School of Medicine and UC San Diego Moores Cancer Center, report that decreases in a specific group of proteins trigger changes in the cancer microenvironment that accelerate growth and development of therapy-resistant cancer stem cells (CSCs). The discovery suggests the basis for a potential new therapeutic approach to eradicate blood cancers, which affect more than 1.1 million Americans. In fact, researchers found...

Combining adult stem cells with hormone may speed bone fracture healing
A combination of adult stem cells and parathyroid hormone significantly increased new bone formation in laboratory animals and may speed the healing process for human bone fractures caused by osteoporosis, a new study shows. The study is published online by Molecular Therapy, a peer-reviewed journal in the Nature Publishing Group. Researchers used a combination of mesenchymal stem cells, which are derived from bone marrow taken from adults, and parathyroid hormone, also called PTH, which...

Researchers identify unique marker on mom's chromosomes in early embryo
Researchers in the University of Georgia's Regenerative Bioscience Center are visually capturing the first process of chromosome alignment and separation at the beginning of mouse development. The findings could lead to answers to questions concerning the mechanisms leading to birth defects and chromosome instability in cancer cells. "We've generated a model that is unique in the world," said Rabindranath De La Fuente, an associate professor in the UGA College of Veterinary Medicine. "Because...

Penn bioengineers show why lab-made stem cells might fail: Errors in DNA folding
Induced pluripotent stem cells hold promise for regenerative medicine because they can, in theory, turn into any type of tissue and because they are made from a patient's own adult cells, guaranteeing compatibility. However, the technique that turns adult cells into these iPS cells is not foolproof; after reverting to their pluripotent state, these cells don't always correctly differentiate back into adult cells. Researchers from the University of Pennsylvania have now discovered one of the...

New procedure allows long-term culturing of adult stem cells
A new procedure developed at Massachusetts General Hospital (MGH) may revolutionize the culturing of adult stem cells. In their report that has been published online prior to its appearance in the August 6 issue of Cell Stem Cell, the team describes generating and expanding airway stem cells from the sorts of tissue samples collected during routine treatment of lung disorders. The overall approach appears applicable to several other tissue types, including skin and the linings of the...

How a single molecule turns one immune cell into another
All it takes is one molecule to reprogram an antibody-producing B cell into a scavenging macrophage. This transformation is possible, new evidence shows, because the molecule (C/EBPa, a transcription factor) "short-circuits" the cells so that they re-express genes reserved for embryonic development. The findings appear July 30 in Stem Cell Reports, the journal of the International Society for Stem Cell Research. Over the past 28 years, researchers have shown that a number of specialized cell...

Genetic code of red blood cells discovered
Eight days. That's how long it takes for skin cells to reprogram into red blood cells. Researchers at Lund University in Sweden, together with colleagues at Center of Regenerative Medicine in Barcelona, have successfully identified the four genetic keys that unlock the genetic code of skin cells and reprogram them to start producing red blood cells instead. "We have performed this experiment on mice, and the preliminary results indicate that it is also possible to reprogram skin cells from...

Gen terapisi ile hasar görmüş kalp kasları başarı ile tedavi edildi
Gen terapisi kardiyak rejenerasyon için umut olabilir mi? Bir kalp krizinden sonra, kalbin bir bölümünde genellikle kalıcı hasar oluşur. Çünkü kardiyak kalp kasları ölümcül şekilde farklılaşır ve kalbe kan akışı bloke olduktan sonra çoğalamaz. Bu kısmi iyileşme ölümün önde gelen nedenlerinden biri olarak kalp hastalığına atfedilebilir. Hücreler bölünmek için uyarılabilseydi ve kalp kendini tamir etmek için uyarılabilseydi ne olurdu?
