Mantendo um registro de infecções anteriores, as células-tronco do sangue aumentam a resposta imune3/13/2020
Blood stem cells boost immunity by keeping a record of previous infections
Date:March 13, 2020 Source:Technische Universität DresdenSummary:Scientists have uncovered a surprising property of blood stem cells: not only do they ensure the continuous renewal of blood cells and contribute to the immune response triggered by an infection, but they can also remember previous infectious encounters to drive a more rapid and more efficient immune response in the future. https://www.sciencedaily.com/releases/2020/03/200313112148.htm How stem cells repair damage from heart attacks
Source: Mayo Clinic Summary: Researchers have uncovered stem cell-activated mechanisms of healing after a heart attack. Stem cells restored cardiac muscle back to its condition before the heart attack, in turn providing a blueprint of how stem cells may work. https://www.sciencedaily.com/releases/2020/03/200313112144.htm New method to grow human blood vessels
Early studies show further applications that could impact donor transplant system Date: March 11, 2020 Source: University of Minnesota Medical SchoolSummary:A team of researchers recently proved the ability to grow human-derived blood vessels in a pig -- a novel approach that has the potential for providing unlimited human vessels for transplant purposes. https://www.sciencedaily.com/releases/2020/03/200311121839.htm Source: University of Zurich
Summary:Scientists have sent adult human stem cells to the International Space Station (ISS). Researchers will explore the production of human tissue in weightlessness. https://www.sciencedaily.com/releases/2020/03/200309093035.htm "Primitive' stem cells shown to regenerate blood vessels in the eye"
Source: Johns Hopkins Medicine Summary: Scientists say they have successfully turned back the biological hands of time, coaxing adult human cells in the laboratory to revert to a primitive state, and unlocking their potential to replace and repair damage to blood vessels in the retina caused by diabetes. The findings from this experimental study, they say, advance regenerative medicine techniques aimed at reversing the course of diabetic retinopathy and other blinding eye diseases. https://www.sciencedaily.com/releases/2020/03/200309093015.htm |
