With their ability to help repair damaged muscle, stem cells have shown promise as tools for rebuilding the body's organs, but their potential is yet to be fully realized – especially when it comes to the heart. Part of this is because only a small percentage of stem cells injected actually survive the process, but a newly developed liquid could make life a little easier for freshly transplanted cells. Researchers have found that encapsulating them in a sticky hydrogel gives them the ability to not only survive, but multiply and improve the injured heart's ability to pump blood.
Respiratory diseases such as bronchitis, emphysema and asthma are extremely prevalent, with more than 35 million sufferers in the US alone. Now, a team from the Weizmann Institute of Science has worked to create a new treatment for repairing damaged lung tissue, using the procedure for bone marrow stem cell transplantation as a template.
A team of researchers from the Temple University School of Medicine (TUSM) has conducted a study involving the use of communications modules secreted by stem cells to help limit the damage caused by a heart attack. The team performed tests on mice, with extremely promising results.
Researchers in Japan have found that human aging may be able to be
delayed or even reversed, at least at the most basic level of human cell
lines. In the process, the scientists from the University of Tsukuba
also found that regulation of two genes is related to how we age.
