Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

Epirubicin is as effective as doxorubicin for cancer treatment with less heart damage, but doesn't work on doxorubicin-resistant cancers.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Latanoprost can make eyelashes longer, thicker, and darker.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Stem cell self-renewal is complex and needs more research for full understanding.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

Alopecia areata is an autoimmune disease causing patchy hair loss, often with other autoimmune disorders, but its exact causes are unknown.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

Different types of stem cells and their environments are key to skin repair and maintenance.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

The conclusion is that Treg-targeted therapies have potential, but more knowledge of Treg biology is needed for effective treatments, including for cancer.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Oxidative stress contributes to hair graying and loss as we age.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Janus kinase inhibitors are promising treatments for autoimmune skin diseases like eczema and psoriasis.

TRP channels in the skin are important for sensation and health, and targeting them could help treat skin disorders.

New targets for making and using brain-synthesized steroids could lead to better treatments for brain disorders and alcoholism.

Different PIN proteins affect plant root hair growth by changing how auxin is transported.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Rhodococcus equi causes severe pneumonia in young foals, and effective vaccines are needed due to foals' weak immune responses.

Potassium channel openers are effective in treating heart conditions, high blood pressure, pulmonary diseases, bladder issues, and hair loss, but more selective drugs are needed.
