Discovered a new molecule - the first of its kind that allows multiplication of stem cells from umbilical cord. This discovery is very important as these cells are used for transplantation for the treatment of blood diseases such as leukemia, lymphoma and myeloma.
 
The blood from the umbilical cord of the infant is considered an excellent source of hematopoietic stem cells that could be used for transplants.
 
These stem cells are less likely to cause an adverse reaction by the immunity in the recipient thereof to whom they are transplanted.
 
Furthermore, unlike the adult stem cells from bone marrow, it is not necessary, and the donor recipient has to have immunological compatibility for successful transplantation.
 
Such type of treatment, however, can not always lead to successful healing in adults, since the number of the collected stem cells from umbilical cord blood is small and insufficient. Scientists believe that by using the new molecule will be possible multiplication of stem cells to a sufficient quantity for the conduct of successful treatment.
 
Molecule is called the UM171 and was discovered by researchers from the Institute of Cancer Research and immunological and the University of Montreal, Canada.
 
Doctrine argue that UM171 has the potential to increase the number of blood units, ready for transplant to 10 times.

Macular degeneration is the leading cause of blindness worldwide. It affects one in five people 75 years of age.
 
The loss of vision is closely related to the aging process. The infringement is not seen so much as an actual condition, but rather as an inevitable part of aging.
 
New discovery by scientists from the UK, however, may soon change this data.
 
Researchers from the University of Southampton, UK, identified a unique type of stem cells in the eye that can be converted into photovoltaic cells. What is more important is that have the potential to turn the processes associated with blindness due to macular degeneration.
 
Affected by the condition suffer from blurred and "distorted" vision before it completely disappears. To a large extent the cause lies in the loss of photoreceptor cells - cells that require light. In this study, the team of researchers found a way to replace these lost cells and reverse the effects of the condition.
 
Right on the front surface of the eye - between the cornea and sclera, is an area where stem cells have been shown to "behave" as photoreceptor when they are in a suitable environment.
 
For the moment, this environment can be created only in the laboratory. Since stem cells exist in the eyes throughout life, it is believed that with more research in this area, they can be used in future therapies for the treatment of blindness caused by macular degeneration.

Treatment of various diseases of the blood and immune system is about to be discovered by scientists that reveal the mystery of the origin of stem cells.
 
Avstraliyskoro study was conducted by the Institute for Regenerative Medicine at Monash University, Melbourne. It first establishes a mechanism that "unlocks" the body in the formation of hematopoietic stem cells (HSC).
 
These cells are found in bone marrow and umbilical cord and are extremely important because they can "feed" the stock of blood cells in the body. Patients with leukemia have been successfully treated with HSC transplantation. Medical experts, however, believe that they can come into wider use.
 
According to the lead researcher - Prof. Peter Curry, understanding the way the HSC is samopodnovyavat to fill blood cells is the "Holy Grail" of stem cell biology.
 
Hematopoietic stem cells are the best therapeutic agent, since they can produce any cell in the body, said Curry, adding that they could be used for the treatment of severe blood diseases. But before that you need to understand how they emerge.
 
During this study, researchers observed cells in the developing zebra fish - tropical freshwater fish known for its regenerative abilities and optically visible embryos.
 
Using a microscope with high resolution scientists capture the manner in which the cells grow. The process of their formation is captured in dramatic detail.
 
Observations found that HSC need a "friendly" type of cell that help their formation. Metaphorically, the researchers explain that these cells serve as a comfortable sofa where HSC accommodate. Researchers establish whether the genes that are required for the formation of these "friendly" cells.
 
The most remarkable achievement of the experts is that they can identify the signals in these cells, helper, which are responsible for the formation of HSC, after which they could be used in vitro for the creation of various blood cells to "fix" all types of diseases related to the blood.
