Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

Certain mature cells in mouse lungs can turn back into stem cells to aid in tissue repair.

Mammary stem cells drive mammary gland growth by branching and cell mixing.

Activating β-catenin in mammary cells leads to changes that cause early-stage abnormal growths similar to skin structures.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Apoptosis is essential for human skin development and forming a functional epidermis.

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

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

Using defensins to activate stem cells may improve skin aging signs without causing inflammation.

The document concludes that identifying the specific cells where skin cancers begin is important for creating better prevention, detection, and treatment methods.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Epithelial stem cells can adapt and help in tissue repair and regeneration.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

Keratins help protect cells, aid in cancer diagnosis, and influence cancer behavior and treatment.

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

The research created a detailed map of skin cells, showing that certain cells in basal cell carcinoma may come from hair follicles and could help the cancer grow.

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

Plet-1 protein helps hair follicle cells move and stick to tissues.

Using neurohormones to control keratin can lead to new skin disease treatments.

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

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Trichoblastomas in rabbits are linked to uncontrolled embryonic hair growth and have distinct histological features.

Runx genes are important for stem cell regulation and their roles in aging and disease need more research.

Keratin proteins are essential for keeping the cells in the human colon healthy and stable.
