An experimental treatment in Spain has shown promising possibilities to rebuild breasts damaged by tumors with the use of fat taken from the patient’s abdomen, removing stem cells, then injecting them into the chest, in a process that takes from four to five hours and does not leave scars.
Five patients from Madrid were the first in Spain to undergo the pioneering operation performed at Gregorio Maranon in collaboration with three other European hospitals in Great Britain, Italy, and Belgium. Mesenchymal stem cells, adult stem cells with the ability to transform into different tissues, are the
Stem cells could be responsible for some forms of aggressive thyroid tumors (ATC, anaplastic thyroid carcinoma). The discovery was made by a young group of biotechnologists, biologists, and doctors from the Endocrinology department of the General Hospital of the University of Palermo. In the study, published in Plos One, the researchers described a subset of tumor stem cells that were able to proliferate continuously and may be responsible for uncontrolled tumor growth. These cells are resistant to chemotherapy and explain why ATC is so highly fatal in such a short period of time. The
About five years ago, Professor Janet Sawicki at the Lankenau Institute in Pennsylvania read an article about nanoparticles developed by MIT’s Daniel Anderson and Robert Langer for gene therapy, the insertion of genes into living cells for the treatment of disease. Sawicki was working on treating ovarian cancer by delivering — through viruses — the gene for the diphtheria toxin, which kills tumor cells (…)

Scientists have developed a new tool that illuminates connections between stem cells and cancer.
Researchers have been successful in breaking apart human prostate tissue, extract the stem cells in the tissue, and alter those cells genetically so that they spur cancer.
Many tissues contain pools of stem cells that replenish the tissue when it’s damaged or when changes take place. For example, stem cells in the skin produce new cells to replace those irreparably damaged by the sun, and stem cells in the breast create milk-producing cells when a woman is pregnant.
A characteristic of these stem cells is that

Here’s a story about life that begins on the No. 2 toe — the one next to the big toe — on the right foot of Jasmina Anema. In early January, a red blip, the size of a bug bite, appeared. It got itchy, and she told her mom, Thea Anema.
“It looked like nothing,” the mother said. Then the foot started to swell. On the morning of Jan. 20, on their way to Jasmina’s kindergarten at Public School 141 in Greenwich Village, they stopped at the pediatrician’s office.
Her abdomen was swollen; a test found
