A protein from certain immune cells is key for new hair growth after skin injury in mice.

Prostaglandin D2 blocks new hair growth after skin injury through the Gpr44 receptor.

Scientists found a way to grow human hair cells in a lab that can create new hair when transplanted.

In vivo confocal scanning laser microscopy is an effective, non-invasive way to study and measure new hair growth after skin injury in mice.

The gene Msx2 is crucial for hair follicle regeneration during wound healing.

An 80-year-old patient grew new hair on a wound, showing that elderly people can still regenerate hair.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Blocking a protein called CXXC5 with a specific peptide can stimulate hair regrowth and new hair growth in wounds.

The stiffness of a wound affects hair growth during healing, with less stiff areas growing more hair.

The gel with icariin speeds up wound healing, reduces scarring, and helps hair growth by controlling BMP4 signaling. It also reduces inflammation and improves wound quality in mice, adapts to different wound shapes, and gradually releases icariin to aid healing. It also prevents too much collagen and myofibroblast formation during skin healing.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Dermal papilla cells help wounds heal better and can potentially grow new hair.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Modified stem cells from umbilical cord blood can make hair grow faster.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Lanyu pigs show that partial-thickness wounds can partially regenerate important skin structures, which may help improve human skin healing.

New suturing technique with wider intervals and shallow stitches helps prevent scalp scars and promotes hair growth.

Researchers developed a scaffold that releases a healing drug over time, improving wound healing and skin regeneration.

Stabilizing HIF1A in hair follicles increases glycolysis, which may help reduce oxidative stress and support hair growth.

Spiny mice are better at regenerating hair after injury than laboratory mice and could help us understand how to improve human skin repair.

Activating TLR3 may help produce retinoic acid, important for tissue regeneration.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Scientists developed a system to study human hair growth using skin cells, which could help understand hair development and improve skin substitutes for medical use.

3D bioprinting can effectively regenerate hair follicles and skin tissue in wounds.

Mouse cell exosomes help hair regrowth and wound healing by activating a specific signaling pathway.

Hydrogel scaffolds can help wounds heal better and grow hair.

Fibroblast Growth Factors (FGFs) are important for tissue repair and regeneration, influencing cell behavior and other factors involved in healing, and are crucial in processes like wound healing, bone repair, and hair growth.

After skin is damaged, noncoding dsRNA helps prostaglandins and Wnts work together to repair tissue and promote hair growth.
