Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.

Nitric oxide gel helps heal skin burns faster by improving skin growth, hair regrowth, and blood vessel formation.

The extracellular matrix is crucial for controlling skin stem cell behavior and health.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

Androgen receptor activity blocks Wnt/β-catenin signaling, affecting hair growth and skin cell balance.

Ephrins slow down skin and hair follicle cell growth.

CD98hc's role in skin health decreases with age.

Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.

Single Blimp1+ cells can create functional sebaceous gland organoids in the lab.

The study found that mouse sweat glands develop before birth, mature after birth, and have specific keratin patterns.

In vivo confocal scanning laser microscopy is an effective, non-invasive way to study and measure new hair growth after skin injury in mice.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Stem cell differentiation is crucial for skin barrier maintenance and its disruption can lead to skin diseases.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Vitamin D and calcium are important for quick and effective skin wound healing.

Telocytes in the scalp may help with skin regeneration and maintenance.

Vitamin D compounds may help treat psoriasis by promoting skin cell differentiation.

Disrupted sleep patterns can harm skin and hair cell renewal, but melatonin might help.

Mice with too much sPLA₂-IIA have hair loss and poor wound healing due to abnormal hair growth and stem cell depletion.

Trichoscopy helps diagnose hair and scalp problems but isn't always definitive and should be used with other methods.

Lichen planopilaris is the most common type of scarring hair loss observed, with a variety of symptoms and tissue changes.

Gentamicin penetrates pig skin better through open hair follicles than blocked ones.

Trichoscopy is a useful tool for diagnosing and managing hair and scalp conditions, often better than traditional methods.

Permanent hair loss after a stem cell transplant can be a sign of chronic immune system attack on the scalp.

The document concludes that treatments for cicatricial alopecia are not well-supported by evidence, but hair transplantation shows more predictable and satisfactory results.

Understanding skin structure and development helps diagnose and treat skin disorders.

Cell death shapes skin stem cell environments, affecting inflammation, repair, and cancer.

A woman with rheumatoid arthritis had a unique type of scarring hair loss not caused by infection, requiring early treatment to avoid permanent hair loss.
