Stem cells switch off and on, sometimes dividing to produce progeny cells and sometimes resting. But scientists don’t fully understand what causes the cells to toggle between active and quiet states (…)
New research in Elaine Fuchs’ Laboratory of Mammalian Cell Biology and Development focused on stem cells in the hair follicle to determine what switches them on. The researchers found cells produced by the stem cells, progeny known at Transit-Amplifying Cells or TACs, emit a signal that tells quiet hair follicle stem cells to become active.
“Many types of mammalian stem cells produce TACs, which act as an intermediate between
Japanese researchers have successfully grown hair on hairless mice by implanting follicles created from adult stem cells, they announced Wednesday, sparking new hopes of a cure for baldness.
Led by professor Takashi Tsuji from Tokyo University of Science, the team bioengineered hair follicles and transplanted them into the skin of hairless mice.
The creatures eventually grew hair, which continued regenerating in normal growth cycles after old hairs fell out.
When stem cells are grown into tissues or organs, they usually need to be extracted from embryos, but Tsuji and his researchers found hair follicles can be grown with adult stem cells, the
Stem Cell Research Study for Baldness in Children
In a new stem cell research study presented at the International Society for Stem Cell Research (ISSCR) annual meeting last week, a dermatologist presented a new clinical research study in which children with Alopecia Areata were treated for baldness with their own Adult Stem Cells.
Adult Stem Cells for […]

Researchers at the University of Sheffield have created the complex hair cells and the neurons needed for hearing from human stem cells.
They found they could encourage stem cells from the inner ears of human foetuses to grow into these highly specialised hearing cells.
The scientists hope they will eventually be able to use the cells to perform cell transplants in deaf patients to replace the hair cells and neurons that are damaged in a form of deafness known as sensorineural hearing loss.
Sensorineural hearing loss one of the most common forms of deafness, accounting for 90
