Scientists have succeeded in creating hair follicles that can naturally grow and attach to tissues. This has been made possible by a research team from the USA and Japan, which integrated the missing cellular component. Previous attempts to create hair follicles in vitro did not ensure their full functionality and growth capability.
A key discovery was the identification of supportive mesenchymal cells that provide a structural framework around the follicle and in the dermal sheath. Previously, only epithelial stem cells responsible for hair formation and dermal papilla cells, which play an important role in growth signaling, were used to create follicles. The inclusion of mesenchymal cells at the early stages of follicle formation proved sufficient to stimulate their full functionality under laboratory conditions.
This research was conducted on mice, and its results open new horizons for developing methods to restore hair growth after it has ceased, as well as potentially aiding in the treatment of baldness. Furthermore, this work has a broader context in the field of regenerative medicine, as understanding the role of less obvious cells can be applied in the bioengineering of other organs.
OrganTech, one of the sponsors of the research, aims to further develop in vitro technology for producing hair follicles, which could lead to effective therapeutic solutions. Laboratory-grown hair may also be used to test new treatments for hair loss and to study growth processes without the need for experiments on humans or animals. This research establishes the basic cellular structure necessary for the regeneration of hair follicles.
