Why does a cancer that seems totally eradicated sometimes reappear? It is the question that physicians and biologists around the world have been asking for years. Now three new studies published in the journals Nature and Science suggest it could have to do with a special type of stem cell.
A Spanish team in collaboration with an American laboratory have just achieved a breakthrough for the world of neurology. According to the research, published in the journal 'Proceedings of the National Academy of Sciences' (PNAS), they have succeeded, for the first time, in transforming cells from the umbilical cord of a newborn baby into neurons, which opens up a world of possibilities for future treatments against neurodegenerative diseases such as Alzheimer's or Parkinson's.
Hair does not regenerate naturally, and when a person loses hair follicles, they go bald. However, a group of researchers from the University of Tokyo (Japan) has managed to regrow hair in hairless mice thanks to a new bioengineering technique and in the future they hope to develop a remedy to treat alopecia.
American scientists have managed to restore the erectile capacity of the penis in rats using adult stem cells from the intestine. The advance heralds a future new method for penile reconstruction in humans, especially in patients suffering from Peyronie's disease.
Scientists from the National Primate Research Center of Oregon (USA) have created the first chimeric monkeys, that is, primates that combine cells with up to six different genomes. Until now the possibility of creating chimeric animals was limited to rodents. The milestone is published in the latest issue of the journal 'Cell'.
French scientists from the Pierre and Marie Curie University in Paris have carried out the first blood transfusion obtained in the laboratory, according to the specialized journal Blood in its latest edition. Luc Douay and his colleagues extracted stem cells from the bone marrow of a volunteer, grew them into red blood cells in the laboratory, and then injected 10 billion of them into the donor.
American scientists have identified certain stem cells in the layer of fat under the skin that send molecular signals that determine when our hair grows. In fact, when hair dies, the fat layer of the scalp shrinks.
A team of scientists from the University of Kyoto (Japan) has managed to produce viable sperm from mouse stem cells in an experiment that, according to the researchers, could lead to a treatment for male infertility in the future. The finding, published in the journal Cell, marks a milestone in the use of stem cells in the field of regenerative medicine.
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.
