Stem cell therapies show promise for treating various diseases but face challenges in clinical use and require better monitoring techniques.

Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.

The gelatin/β-TCP scaffold with nanoparticles improves wound healing and skin regeneration.

Men with baldness due to androgenetic alopecia still have hair stem cells, but lack specific cells needed for hair growth.

Scientists successfully created and transplanted bioengineered hair follicles that function like natural ones, suggesting a new treatment for hair loss.

β-Catenin signaling is involved in brain cell growth after injury and could be a therapy target.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Alcohol extract from Vernonia anthelmintica seeds may help treat stress-related hair loss.

The technique allowed noninvasive tracking of hair stem cell survival and growth, showing potential for hair loss research.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Using fat stem cells and blood cell-rich plasma together improves healing in diabetic wounds by affecting cell signaling.

Plant extracts may help prevent or reverse hair graying.

Wnt10b helps blood stem cells grow after injury.

Skin structure complexity and variability are crucial for assessing skin toxicity in safety tests.

Vitamin D Receptor is needed for hair growth in mice but not for skin stem cell maintenance.

Muscles and nerves that cause goosebumps also help control hair growth.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

The HR protein's role as a repressor is essential for controlling hair growth.

Stem cells from hair follicles in a special gel show strong potential for bone regeneration.

Fat stem cells from diabetic mice can still help heal wounds.

Peptide hydrogels show promise for healing skin, bone, and nerves but need improvement in stability and compatibility.

Stress in hair follicle stem cells causes inflammation in a chronic skin condition through a specific immune response pathway.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Using defensins to activate stem cells may improve skin aging signs without causing inflammation.

Improved understanding of stem cell mechanisms can enhance skin tissue engineering.

Fat tissue stem cells show promise for repairing different body tissues and are being tested in clinical trials.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Improving the environment and cell interactions is key for creating human hair in the lab.
