Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

Aging causes skin stem cells to work less effectively.

Cannabinoids may help treat various skin conditions.

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 aging is a complex process influenced by various factors, leading to wrinkles and sagging, and should be considered a disease due to its health impacts.

The document concludes that understanding the sebaceous gland's development and function is key to addressing related skin diseases and aging effects.

Skin-derived precursors in hair follicles come from different origins but function similarly.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

Skin fat helps with body temperature control and has other active roles in health.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Activating Nrf2 in skin cells causes skin disease similar to chloracne in mice.

The nude gene causes skin cell overgrowth and improper development, leading to hair and urinary issues.

Nuclear hormone receptors play a significant role in skin wound healing and could lead to better treatment methods.

Hair follicle stem cells are a promising source for tissue repair and treating skin or hair diseases.

Noggin overexpression delays eyelid opening by affecting cell death and skin cell development.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Fat from the body can help improve hair growth and scars when used in skin treatments.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.

C/EBPalpha and C/EBPbeta are crucial for normal skin and oil gland cell development in adult mice.

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

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.

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

Mesenchymal stem cells help improve wound healing by reducing inflammation and promoting skin cell growth and movement.

Scientists created hair-growing skin models from stem cells, which could help treat hair loss and skin diseases.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

Sweat glands and hair follicles are structurally connected within a specific layer of skin fat.

Cells from a skin condition can create new hair follicles and similar growths in mice, and a specific treatment can reduce these effects.
