Stem Cells News and Research

RSS

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Roundup: Ga. 'provider fee' defeat could mean $430M less for Medicaid; Minn. health programs in line for $37M cut over fiscal cliff; Calif. stem cell board criticized

Just weeks before the 2013 General Assembly convenes, the state's provider fee, called a "bed tax" by some, remains a high-profile wild card -- one that could deal Georgia's hospital industry a crippling blow. If the fee is not renewed -- and anti-tax forces will oppose it -- the Medicaid system may lose $430 million-plus that the assessment now generates. That loss would swell the state's Medicaid financial shortfall, which is already about $400 million (Miller, 12/6).

Noncoding DNA sequence required for epidermal differentiation

The differentiation of human epidermis is controlled and stabilized by a long noncoding RNA termed terminal differentiation-induced noncoding RNA acting through a post-transcriptional mechanism, the results of an innovative US study indicate.

SOX2 directly regulated by tumor suppressor CDKN1B(p27) gene

A team of researchers from the Spanish National Cancer Research Centre (CNIO), led by Manuel Serrano, from the Tumour Suppression Group, together with scientists from London and Santiago de Compostela, has discovered that the cellular reprogramming gene SOX2, which is involved in several types of cancers, such as lung cancer and pituitary cancer, is directly regulated by the tumor suppressor CDKN1B(p27) gene, which is also associated with these types of cancer.

Scientists identify key molecular pathway that leads to depression

Scientists have identified the key molecular pathway leading to depression, revealing potential new targets for drug discovery, according to research led by King's College London's Institute of Psychiatry. The study, published today in Neuropsychopharmacology, reveals for the first time that the 'Hedgehog pathway' regulates how stress hormones, usually elevated during depression, reduce the number of brain cells.

Moderna Therapeutics closes $40M in financing

Moderna Therapeutics announced today that it has closed more than $40 million in financing to date, led by Flagship Ventures and private investors, which will be used to advance multiple programs toward clinical stage development.

New method can generate stable human mesenchymal stem cells for bone engineering

Human mesenchymal stem cells (hMSCs) can develop into bone cells and are useful for tissue engineering and regeneration. However, when grown in the laboratory they quickly lose their ability to continue dividing and they die.

New method promises to boost stem cell production in laboratory

A new method for generating stem cells from mature cells promises to boost stem cell production in the laboratory, helping to remove a barrier to regenerative medicine therapies that would replace damaged or unhealthy body tissues.

Researchers derive dopaminergic neurons from bone marrow stem cells in monkeys

Parkinson's disease is a degenerative disorder of the central nervous system that is characterized by tremors, rigidity, slowness of movement, and difficulty walking. It is caused by loss of the neurons that produce the neurotransmitter dopamine (known as dopaminergic neurons). One of the primary goals in Parkinson's disease research is to develop a replacement for dopaminergic neurons.

microRNAs play an important role during embryonic development

Sanford-Burnham researchers discover that microRNAs play an important role in germ layer formation-the process that determines which cells become which organs during embryonic development

TINCR molecule plays a master role in epidermal differentiation

The surface of your skin, called the epidermis, is a complex mixture of many different cell types - each with a very specific job. The production, or differentiation, of such a sophisticated tissue requires an immense amount of coordination at the cellular level, and glitches in the process can have disastrous consequences. Now, researchers at the Stanford University School of Medicine have identified a master regulator of this differentiation process.

Loss of either T-bet or Eomes protein reduces immune system's ability to fight viral infection

When you get an acute infection, such as influenza, the body generally responds with a coordinated response of immune-cell proliferation and attack that rapidly clears the pathogen. Then, their mission done, the immune system stands down, leaving a population of sentinel memory cells to rapidly redeploy the immune system in the event of reinfection.
