In the bone marrow, the cells of the blood and the immune system are manufactured, that is why the marrow donation is, in many cases, the hope against leukemia. Stem cells, also known as hematopoietic progenitors, nest in this area of the body, capable of producing all blood cells: white blood cells, red blood cells, and platelets. In this way, a bone marrow transplant allows the cure of certain diseases derived from the abnormal production of certain cells derived from stem cells by replacing these defective cells with normal ones from a healthy patient, but can everyone be a donor? of marrow?
Scientists at Stanford University, in the United States, have managed to convert skin cells into active neurons by adding four proteins to them, through a process that lasts four to five weeks, according to 'Nature'.
Japanese researchers have for the first time succeeded in converting stem cells from a mammal into an embryonic eye. The results, which are echoed in the journal 'Nature', raise the possibility that in the future sight of blind people with transplanted retinas generated from the patient's own stem cells may be restored.
Using stem cells from young patients with a severe congenital defect that affects the heart, scientists at the Stanford University School of Medicine have created heart cells capable of beating that carry the same genetic mutation as the sick. In this way, they will be able to study the disease in the laboratory in search of a cure.
The BBVA Foundation Frontiers of Knowledge Award in Biomedicine has been awarded in its third edition to Shinya Yamanaka for "demonstrating that it is possible to reprogram already differentiated cells and thus return them to a state of pluripotent cells".
Using stem cell technology, Texas reproductive science experts, led by Richard R. Berhringer, have created a male and a female from two parents. The milestone has been published in the journal 'Biology of Reproduction'.
Dutch scientists have discovered the most primitive stem cell in the skin in the hair roots of mice. These cells are capable of regenerating the three different layers of the epidermis, which could lead to new treatments to heal wounds and burns, as well as antidotes to baldness.
In those extra kilos that are fixed in the form of fat on the waist, belly or hips hide a series of cells that can be transformed into pluripotent and used to repair all kinds of tissues.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
