December 2010 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” New cells join the hair's dermal papilla during the growth phase, possibly affecting hair thickness.
January 2009 in “China Practical Medicine” Certain genes help dermal papillae cells in hair follicles grow and group together.
April 2023 in “Journal of Investigative Dermatology” Proper cell death regulation is crucial for normal hair follicle regeneration and skin remodeling.
April 2023 in “ACS Biomaterials Science & Engineering” 3D scaffolds mimicking the extracellular matrix are crucial for effective hair follicle regeneration.
July 2022 in “Journal of Investigative Dermatology” TRPS1 loss in balding scalp areas contributes to hair loss in androgenic alopecia.
January 2022 in “Stem cell biology and regenerative medicine” New hair can grow at wound sites, which could help improve treatments for hair loss and wound healing.
December 2016 in “Paleontological Journal” Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.
August 2013 in “Nature Reviews Drug Discovery” A protein called FGF9 helps regenerate hair follicles in mice after skin damage, and increasing FGF9 could potentially help human hair growth.
December 2012 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.
October 2012 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.
Hair follicle-like structures can form when specific hair cells are mixed and implanted in mice.
