A new keratin, hK6irs1, is found in all layers of the hair follicle's inner root sheath.

Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.

The cornified cell envelope forms a protective barrier in skin and hair, using specific proteins and lipids to maintain effectiveness.

Cattle skin has leptin which might control skin and hair growth.

Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Wnt ligand secretion by hair follicle cells is essential for hair growth and repair.

There are two types of stem cells in rodent hair follicles, each with different keratin proteins.

The research maps the complex development of early mouse skin, identifying diverse cell types and their roles in forming skin layers and structures.

Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.

Hair follicles create different cell layers and proteins, controlled by various molecules.

Hair follicle development involves complex interactions between skin layers and cells, but many details are still unknown.

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.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

The enzymes Aldh1a2 and Aldh1a3 are involved in making retinoic acid in hair follicles and have different roles in hair growth.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.

Keratinocytes from dog hair follicles can create a functional skin layer in a lab model, useful for dog skin therapy.

EZH2 is essential for hair growth and skin cell development.

A new protein was made to detect specific skin cell growth receptors and worked in normal skin but not in skin cancer cells.

Retinoic acid production and signaling in hair follicles are regulated by location and timing, affecting hair growth and cycling.

Hair in mammals likely evolved from glandular structures, not scales.

A one-year-old cat had multiple benign skin tumors similar to those known in humans.

The Siah1 and Siah2 genes are active in mouse skin development and hair growth, especially right after birth.

New findings suggest targeting IL-23 could treat psoriasis, skin cells can adapt to new roles, direct conversion of skin cells to blood cells may aid cell therapy, removing certain tumor cells could boost cancer immunotherapy, and melanoma may have many tumorigenic cells, not just cancer stem cells.

The conclusion introduces a new way to classify skin cysts using their shape and genetic markers.

Human hair follicle dermal cells can effectively replace other cells in engineered skin.

Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.

TGF-alpha is present in sheep and ferret skin and may affect hair growth without directly stimulating cell proliferation.

Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.
