Brief summary of the article

Scientists discovered a missing support cell that allows hair follicles grown in the lab to develop properly.
Using this cell with two other known cell types, researchers were able to grow complete hair follicles that produced real hair. When these lab grown follicles were placed onto mice, they connected with surrounding tissue and went through normal hair growth and shedding cycles.

The finding could help scientists develop future treatments for hair loss if the same method can be adapted for human hair follicles.

Main Points of the Article

"Researchers... successfully grown complete, fully functional hair follicles outside of the living body, in a dish."

"This was made possible by the discovery of a previously unknown third cell type, the accessory mesenchymal cell population, which is essential for growing functional hair follicles."

"These specific supporting cells allow the follicle to grow deep into the skin... to produce a proper hair shaft."

"By adding the newly identified cell type... researchers were able to create organ germs... composed of three types of adult stem cells."

"Under carefully controlled lab conditions, these organ germs grew into fully functional hair follicles."

"When transplanted on skin, they survived and went through the hair's natural life cycle."

"Producing truly natural, fully functional hair in laboratory settings has long been a challenge for scientists."

"Hair... undergoes repeated cycles of growth, shedding and regeneration throughout our lifetime."

A very interesting article considering the attempts to clone human hair
