Stem-cell-based strategy boosts immune system in mice 
Raising hopes for cell-based therapies, UC San Francisco researchers have created the first functioning human thymus tissue from embryonic stem cells in the laboratory. The researchers showed that, in mice, the tissue can be used to foster the development of white blood cells the body needs to mount healthy immune responses and to prevent harmful autoimmune reactions.

Divide and define: Clues to understanding how stem cells produce different kinds of cells
The human body contains trillions of cells, all derived from a single cell, or zygote, made by the fusion of an egg and a sperm. That single cell contains all the genetic information needed to develop into a human, and passes identical copies of that information to each new cell as it divides into the many diverse types of cells that make up a complex organism like a human being.

Turning human stem cells into brain cells sheds light on neural development
Medical researchers have manipulated human stem cells into producing types of brain cells known to play important roles in neurodevelopmental disorders such as epilepsy, schizophrenia and autism. The new model cell system allows neuroscientists to investigate normal brain development, as well as to identify specific disruptions in biological signals that may contribute to neuropsychiatric diseases

Investigating devastating childhood diseases just got easier
Induced pluripotent stem cells (iPScs) from the skin of patients with Dravet syndrome (DS) show Dravet-like functional impairment when they are converted into neurons, finds research in BioMed Central's open access journal Molecular Brain. This method provides a non-invasive way to investigate diseases which affect the nervous system of humans.

Metastasis stem cells in the blood of breast cancer patients discovered
Individual cancer cells that break away from the original tumor and circulate through the blood stream are considered responsible for the development of metastases. These dreaded secondary tumors are the main cause of cancer-related deaths. Circulating tumor cells (CTCs) detectable in a patient's blood are associated with a poorer prognosis. However, up until now, experimental evidence was lacking

Declining levels of the protein BubR1 occur when both people and animals age, and contribute to cell senescence or deterioration, weight loss, muscle wasting and cataracts. Mayo Clinic researchers have shown that adult progenitor or stem cells -- important for repair and regeneration of skeletal muscle and maintenance of healthy fat tissue -- are subject to cellular senescence,

Deep inside your brain, a legion of stem cells lies ready to turn into new brain and nerve cells whenever and wherever you need them most. While they wait, they keep themselves in a state of perpetual readiness – poised to become any type of nerve cell you might need as your cells age or get damaged.

The field of regenerative medicine holds great promise, propelled by greater understanding of how stem cells differentiate themselves into many of the body's different cell types. But clinical applications in the field have been slow to materialize, partially owing to difficulties in replicating the conditions these cells naturally experience.

Stem cells use signal orientation to guide division
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.
