Different types of sun exposure damage skin cells and immune cells, with chronic exposure leading to more severe and lasting damage.

Researchers found key regions in the mouse hairless gene that control its activity in skin and brain cells, affecting hair follicle function.

The conclusion is that grasping how cells determine their roles through evolution is key, with expected progress from new research models and genome editing.

Cicatricial alopecia, a permanent hair loss condition, is mainly caused by damage to specific hair follicle stem cells and abnormal immune responses, with gene regulator PPAR-y and lipid metabolism disorders playing significant roles.

Hair follicle stem cells can form both hair follicles and skin.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

Activating TERT in mice skin boosts hair growth by waking up hair follicle stem cells.

Prostate cancer cells can make their own androgens to activate the androgen receptor, and treatments like abiraterone may increase this ability, suggesting new therapies should target the entire steroid-making pathway.

Changing how mesenchymal stromal cells are grown can improve their healing abilities.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Different fibroblasts play key roles in skin healing and scarring.

Aging causes skin stem cells to work less effectively.

The right cells and signals can potentially lead to scarless wound healing, with a mix of natural and external wound healing controllers possibly being the best way to achieve this.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Nanoparticles can deliver vaccines through hair follicles, triggering immune responses and providing protection.

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.

Valproic Acid helps regrow hair in mice and activates a hair growth marker in human cells.

Epidermal stem cells don't use gap junctions to communicate.

WNT10A helps esophageal cancer cells spread and keep renewing themselves.

Tcf3 helps cells move and heal wounds by controlling lipocalin 2.

Mice with human fetal thymic tissue and stem cells developed symptoms similar to chronic graft-versus-host disease.

Scientists found cells in hair that are key for growth and color.

Eccrine sweat gland's clear cells likely cause excessive sweating in hyperhidrosis.

Dihydrotestosterone can be made from dehydroepiandrosterone in skin cells without needing testosterone.

Thioredoxin reductase 1 does not affect glucocorticoid receptor activity in hair follicle cells.

Melanocyte stem cells are crucial for skin pigmentation and have potential in disease modeling and regenerative medicine.

A long-acting Vitamin C derivative helps hair grow by stimulating cells and increasing growth factors.

Platelet-rich plasma can help grow more mouse hair follicles, but it doesn't work for human hair follicles yet.

miR-181a-5p helps hair growth by activating a specific signaling pathway.
