Tissue that is typically discarded in routine hip replacement operations may offer a rich untapped source of stem cells that could be banked for later use in regenerative medicine, where patients’ own cells are used to treat disease or repair failing organs. This was the implication of a new study led by the University of […]

It’ll make you cry, or salivate. Takashi Tsuji at Tokyo University of Science in Japan, and colleagues have created tear and salivary glands from stem cells and successfully transplanted them into adult mice. The technique could one day be used in humans to replace glands lost through age or illnesses such as autoimmune disease and […]

Why rely on mouse brains to help us understand our most complex organ when you can grow a model of a human one? Tiny “brains” that include parts of the cortex, hippocampus and even retinas, have been made for the first time using stem cells. The 3D tissue structures will let researchers study the early […]

For the first time, the light-sensing cells found in the retina have been grown from scratch in the lab, and then successfully transplanted into the eyes of blind mice. The transplanted cells successfully matured and connected with nerves that transmit visual signals to the brain. The researchers say that if the procedure can be repeated […]
