Small proline-rich proteins and trichohyalin help make epithelial tissues tougher and more flexible.

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

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Hair and nail cells share similar proteins, indicating a common differentiation pathway.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

Wnt1/βcatenin signaling is crucial for heart repair after injury.

Understanding where cancer cells come from helps create better prevention and treatment methods.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Hair color production in mice is closely linked to the hair growth phase and may also influence hair growth itself.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Different fibroblasts play key roles in skin healing and scarring.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

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.

Mouse Notch is important for determining cell roles in hair follicles.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

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

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

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.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

Thyroid hormone receptor β1 is found in human hair follicles and helps them survive.

Oral retinoids are effective for various skin conditions but have side effects and should not be used during pregnancy.

NGAL indicates abnormal skin cell differentiation.

Wool follicles are complex, involving interactions between different cell types and structures.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

TNF family proteins are crucial for the development of skin features like hair, teeth, and mammary glands.

Nerve growth in mouse skin and hair follicles happens in stages and is closely linked to hair development.
