Scientists have managed to create hair follicles in artificial conditions that can undergo natural growth cycles and connect with tissues. This became possible thanks to a research team from the USA and Japan, which integrated a previously missing cellular component.
Earlier experiments to create follicles in vitro did not allow them to function properly. Their correct operation was only observed after transplantation into living organisms. The key discovery was the use of a third type of cell — auxiliary mesenchymal cells. Previous studies only used epithelial stem cells, responsible for hair formation, and dermal papilla cells, which regulate growth signals.
Mesenchymal cells provide a framework and structural basis around the follicle and in the dermal sheath. Their addition at early stages of follicle formation was sufficient to initiate complete growth cycles and connect with tissues in laboratory conditions. Thus, a three-cell "recipe" necessary for obtaining a full-fledged hair follicle was identified.
The research was conducted on mouse models and opens new horizons for developing methods to restore hair growth after natural cessation, as well as potentially contributing to the creation of technologies for treating baldness. The results of this work have a broader context for regenerative medicine, as understanding the role of important cells can be used for bioengineering other organs.
The company OrganTech, one of the sponsors of the research, aims to further develop the technology for producing hair follicles in vitro to create effective therapeutic solutions. Laboratory-grown hair can also be used to evaluate new treatments for hair loss and to study growth processes in detail without the need for testing on animals or humans. This research defines the essential cellular configurations necessary for the functional restoration of hair follicles.
