Super-sonic signal: A signal from Transit-Amplifying Cells (TACs) activates stem cells in the hair follicle, researchers have found. Both types of cells appear in green (top), with TACs clustered lower down. The researchers identified the signal as Sonic Hedgehog. In
a bid to improve glaucoma treatments and open prospects for personalized medicine, researchers have succeeded in making retinal ganglion cells from stem cells derived from human skin cells. They report their work in the journal Stem Cells. The researchers say
Dr. Zheng-Yi Chen. Credit: Garyfallia Pagonis Sensory hair cell loss is the major cause of hearing loss and balance disorders. The postnatal mammalian inner ear harbors progenitor cells which have the potential for hair cell regeneration and hearing recovery, but
Why people lose their locks in old age may be related to the aging of hair follicle stem cells, two new studies suggest. Though it is known that mammals that live for longer lifespans lose their hair, the mechanisms underlying
British researchers have found a new way to identify immune cells capable of detecting tumors — opening a path to treatments that could trigger the body’s natural defenses to wipe out cancer. The discovery by scientists at University College, London
