Careful selection of mice by genetics and age, and controlled housing conditions improve the reliability of hair regrowth in wound healing tests.

Nivolumab treatment led to hair regrowth in a man with metastatic melanoma and alopecia areata.

Polydopamine is a safe, effective, and permanent hair dye that turns gray hair black in one hour.

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.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

Mice that can regenerate tissue have cells that pause in the cell cycle, which is important for healing, similar to axolotls.

Early-stage skin cells help regenerate hair follicles, with proteins SDF1, MMP3, biglycan, and LTBP1 playing key roles.

Th22 cells are essential for Tβ15-induced hair growth in mice.

The protein aPKCλ is crucial for keeping hair follicle stem cells inactive and for hair growth and regeneration.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Cells lacking the Bax protein can outcompete others, leading to better tissue repair and hair growth.

Bead-jet printing of stem cells improves muscle and hair regeneration.

The study introduced a new imaging technology to track skin healing and bone marrow cell activity over time.

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.

TPA promotes hair growth by increasing stem cell activity and activating specific cell signals.

Different stem cells are key for hair growth and health, and understanding their regulation could help treat hair loss.

Biomaterials with MSC-derived substances could improve tissue repair and have advantages over direct cell therapy.

Different cell types work together to repair skin, and targeting them may improve healing and reduce scarring.

Cell-based therapies using dermal papilla cells and adipocyte lineage cells show potential for hair regeneration.

Serenoa repens extract helps regrow hair and repair hair loss by activating certain cell growth pathways.

The skin's microbiome helps hair regrow by boosting certain cell signals and metabolism.

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

Photobiomodulation helps hair regrow in injured skin by aiding cell movement and secretion.

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

Researchers found a way to create cells from stem cells that act like human cells important for hair growth and could be used for hair regeneration treatments.

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.

Mice with enhanced regeneration abilities may help develop new regenerative medicine therapies.

Inflammation helps stem cells repair tissue by directing their behavior.

Mice with more Flightless I protein grew back their claws better after amputation.

MicroRNA-205 helps hair grow by changing the stiffness and contraction of hair follicle cells.
