Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Disrupting Stat3 in hair follicle stem cells greatly reduces skin tumor formation.

Tooth papilla cells can help regenerate hair follicles and grow hair.

Mitoxantrone is effective for treating acute leukemia, especially in older patients, with a lower risk of heart damage.

Epidermal keratinocytes start wound healing and inflammation after schistosome infection.

The hair follicle infundibulum plays a key role in skin health and disease, and understanding it better could lead to new skin disease treatments.

Too much thymosin beta4 causes weird teeth and more hair growth in mice.

Mice without collagen VI have slower hair growth normally but faster regrowth after injury.

Crataegus pinnatifida extract may help increase hair growth and thickness in mice.

Blocking TSLP reduces skin inflammation and cell overgrowth in psoriasis.

The study found stem cells in minor salivary glands that can differentiate and are involved in tumor formation when exposed to tobacco.

Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.

Genetic mutation and carcinogen treatment are both needed for skin cancer to develop in these specific mice.

Tridax procumbens is a widely used medicinal plant with many health benefits.

Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.

Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.

Doxazosin mesylate and saw palmetto cause genetic changes in fruit flies.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

Skin aging reflects overall body aging and can indicate internal health conditions.

Hair ages and thins due to factors like inflammation and stress, and treatments like antioxidants and hormones might improve hair health.

Chemicals and stem cells combined have advanced regenerative medicine with few safety concerns, focusing on improving techniques and treatment effectiveness.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Keratin 15 expression in skin cells is regulated by two mechanisms involving PKC/AP-1 and FOXM1.

Bioengineering can potentially treat hair loss by regenerating hair follicles and cloning hair, but the process is complex and needs more research.

The review concludes that innovations in regenerative medicine, tissue engineering, and developmental biology are essential for effective tissue repair and organ transplants.

The new method using gene-modified stem cells and a 3D printed scaffold improved skin repair in mice.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

One Ashwagandha extract may help protect cells with its antioxidant properties, while another could promote hair growth.

Human skin xenografting could improve our understanding of skin development, renewal, and healing.
