Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Common gut bacteria use protein delivery systems to interact directly with human cells, reshaping how scientists view the ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants. A study by UT ...

Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The ...

Researchers with the global Human Cell Atlas (HCA) consortium report significant progress in their quest for a better understanding of the cells of the human body in health and disease, with the ...

Researchers have developed mice with organs containing human cells, using a convenient and surprising approach — injecting the cells directly into the amniotic fluid of pregnant mice. The method ...
