UNIVERSITY OF HELSINKI Hair follicle stem cells, which promote hair growth, can prolong their life by switching their metabolic state. In experiments conducted with mice, a research group active in Helsinki and Cologne, Germany, has demonstrated that a protein called Rictor holds a key role in the process. The study was published in the Cell Metabolism journal. New information...

Fine-tuning stem cell metabolism prevents hair loss
by University of Cologne Cross-section of a skin biopsy showing hair follicles extending downwards from the skin surface. Low oxygen around the hair follicle stem cells activates Rictor signaling (phosphorylated Akt; in magenta) locally at this site. Cell nuclei are labeled in blue. A team of researchers from Cologne and Helsinki has discovered a mechanism that prevents hair...
