Cell polarity signaling controls tissue mechanics and cell fate, with complex interactions and varying pathways across species.

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.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

Human foreskin does not show aging or reduced cell growth after radiation, and H2A.J is not a good marker for radiation-induced aging.

The study concluded that the new wound model can be used to evaluate skin regeneration and nerve growth.

Scientists successfully grew mini hair follicles using human skin cells, which could help treat baldness.

Fibroblast state switching is crucial for skin healing and development.

Kangfuxin (KFX) extract speeds up wound healing and improves skin regeneration.

Fat cells are important for tissue repair and stem cell support in various body parts.

Collagen makes skin stiff, and preservation methods greatly increase tissue stiffness.

The PDGF/PDGFR pathway is a potential drug target with mixed success in treating various diseases, including some cancers and fibrosis.

3D bioprinting is useful for making tissues, testing drugs, and delivering drugs, but needs better materials, resolution, and scalability.

Scientists recreated human hair follicles in the lab that can grow hair.

Researchers created a lab model to study human hair growth, showing it can grow and self-regulate outside the body.

The first pediatric case of naevus trichilemmocysticus was documented.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.

Adult skin cell-based early-stage skin substitutes improve wound healing and hair growth in mice.

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

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

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

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

Growth factors are crucial for hair development and could help treat hair diseases.

Stem cell therapy is a promising approach for hair regrowth despite potential side effects.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

Sebaceous glands can heal and regenerate after injury using their own stem cells and help from hair follicle cells.

The fascial layer is a promising new target for wound healing treatments using biomaterials.

Too much β-catenin activity can mess up the development of mammary glands and make them more like hair follicles.

Regenerative medicine may help reduce radiotherapy side effects like skin cancer, fibrosis, pain, and hair loss.

Lab-grown nail cells show characteristics similar to natural nail and hair.
