Scientists have grown a human hair follicle in a laboratory. The research will better understand the mechanism of growth and hair loss, according to a study by Stanford University scientists published in the journal Nature.
In the course of the work, the researchers created an organoid – a small cell group that mimics human skin grown in a laboratory. It is made from pluripotent stem cells, or master cells, which are present in the body in the early stages of embryonic development, and then turn into specific types of cells.
The resulting artificial skin region was the first development that allowed in the laboratory to achieve growth and hair loss, the authors note.
“This allows you to produce human hair for science without taking it away from a person. For the first time, we managed to get a more or less unlimited source of human hair follicles for research”.Karl Köhler, lead author of the research
The study will help scientists better understand the causes of baldness and other problems with hair growth and development.
