Summary:
A type of cell found naturally in the body holds hope of treatments for muscle diseases such as muscular dystrophy, say UK scientists. It has long been suspected but never proved that satellite cells which coat muscles can make new muscle. The Medical Research Council and experts at University College London have now shown this is the case, at least in mice.

New Finding May Aid Adult Stem Cell Collection
Source: University of Cincinnati
Posted: July 27, 2005
Summary:
Scientists have discovered how blood-regenerating stem cells move from bone marrow into the blood stream. The finding has led to the development of a new chemical compound that can accelerate this process (called stem cell mobilization) in mice--which could eventually lead to more efficient stem cell harvesting for human use.

Well-known Protein Helps Stem Cells Become Secretory Cells
Source: Johns Hopkins Medical Institutions
Date: July 26, 2005
Summary:
Johns Hopkins researchers have discovered that a single protein regulates secretion levels in the fruit fly’s salivary gland and its skin-like outer layer. Described in the May 15 issue of Development, the finding improves understanding of how cells become specialized for secretion, which is a critical ability of certain glands and cell types in organisms from insects to humans.

Stem cells key to development of neck
Source: Guardian Unlimited - UK
Date: July 21, 2005
Summary:
British scientists have identified the cell machinery that gave animals a head start - by evolving a neck to go on their shoulders.
They have discovered that two kinds of embryo stem cell begin the process of fitting a neck to the shoulders, while attaching the appropriate muscles to the right bones. In effect, muscle and bone are not separate components but composite ones.

Stem cell clue to birth defects
Source: BBC News
Date: July 20, 2005
Summary:
BBC News reports on a new finding about the role stem cells play in human development that could lead to treatments for babies with birth defects:
"A discovery of how stem cells form the neck and shoulders could help babies born with birth defects. Scientists had thought muscle and bone tissue in the neck and shoulders was made from entirely distinct and separate types of stem cells. Dr Georgy Koentges and colleagues were able to show this was not the case. By following the development of animal embryos they found one stem cell group made not only muscles in the neck and shoulder, but also the skeletal structures where these muscles attached. They believe the findings will shed light on diseases where things go wrong with the development of such structures."

Functioning Neural Network Grown from Stem Cells
Source: Neurosurgery via Medical News Today
Date: July 18, 2005
Summary:
Physicians have successfully produced functioning neurons from adult stem cells harvested from the ventricle area of a donor's brain. The neurons were proven capable of communicating through synapses and holds promise that patients suffering from degenerative conditions such as Parkinson's disease, epilepsy and Huntington's chorea may one day be treated by growing enough neurons to replace cells destroyed by the disorders. The physicians believe this study presents direct evidence of synaptic transmission between neurons grown from stem cells.

Summary:
Researchers at the San Raffaele Hospital (Milan, Italy) published unexpected results of studies in which immature nerve cells (adult mouse neural stem cells) injected into the blood of mice with MS-like disease were able to suppress the immune attacks that damage the brain and spinal cord tissues.

Date: July 5, 2005
Summary:
Researchers at the University of Minnesota have identified for the first time a group of genes that impact the development and function of blood stem cells, a discovery that brings researchers a step closer to harnessing the power of stem cells for disease treatments. This research provides insight into understanding how to stimulate blood stem cells to multiply so that scientists could generate enough cells from a single umbilical cord to treat more patients.
