LA JOLLA—The ability to grow the cells of one species within an organism of a different species offers scientists a powerful tool for research and medicine. It’s an approach that could advance our understanding of early human development, disease onset and progression and aging; provide innovative platforms for drug evaluation; and address the critical need for transplantable organs. Yet developing such capabilities has been a formidable challenge.
LA JOLLA—Juan Carlos Izpisua Belmonte, a professor in Salk’s Gene Expression Laboratory, has been named one of TIME magazine’s 50 most influential people in healthcare for his scientific innovations in addressing the shortage of human organs for transplant. The list, which is curated by TIME’s health reporters and editors, recognizes people who changed the state of healthcare in America this year, and bear watching for what they do next.
LA JOLLA—Like an actor who excels at both comedy and drama, proteins also can play multiple roles. Uncovering these varied talents can teach researchers more about the inner workings of cells. It also can yield new discoveries about evolution and how proteins have been conserved across species over hundreds of millions of years.
LA JOLLA—The process by which embryonic stem cells develop into heart cells is a complex process involving the precisely timed activation of several molecular pathways and at least 200 genes. Now, Salk Institute scientists have found a simpler way to go from stem cells to heart cells that involves turning off a single gene.
LA JOLLA—Graying hair, crow’s feet, an injury that’s taking longer to heal than when we were 20—faced with the unmistakable signs of aging, most of us have had a least one fantasy of turning back time. Now, scientists at the Salk Institute have found that intermittent expression of genes normally associated with an embryonic state can reverse the hallmarks of old age.
LA JOLLA—Salk Institute researchers have discovered a holy grail of gene editing—the ability to, for the first time, insert DNA at a target location into the non-dividing cells that make up the majority of adult organs and tissues. The technique, which the team showed was able to partially restore visual responses in blind rodents, will open new avenues for basic research and a variety of treatments, such as for retinal, heart and neurological diseases.
LA JOLLA—Salk Institute scientists have discovered the holy grail of endless youthfulness—at least when it comes to one type of human kidney precursor cell. Previous attempts to maintain cultures of the so-called nephron progenitor cells often failed, as the cells died or gradually lost their developmental potential rather than staying in a more medically useful precursor state.
