The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.

Pilomatricoma is a rare, harmless skin lump that needs accurate diagnosis and timely treatment.

Mouse skin fibroblasts vary in function and adaptability based on their environment.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

Sensory neuron remodeling and Merkel-cell changes in the skin happen independently.

Hair follicle stem cells can turn into many cell types and may help repair nerve damage and have other medical uses.

Keratinocytes help keep hair follicle cells and skin cells separate in 3D cultures, which is important for hair growth research.

Certain proteins help nerve cells branch, and other findings relate to cancer, stem cell behavior, and cell division.

Stem cells help heal wounds by rapidly dividing and migrating to the wound edge.

Human stem cells can turn into functional eye cells that might help treat retinal diseases.

Biomimetic nanovesicles can speed up diabetic wound healing by regulating immune cell behavior and metabolism.

Epidermal stem cells don't use gap junctions to communicate.

Scientists can control how skin stem cells divide by using different treatments.

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 stem cells are promising for healing wounds and skin regeneration due to their accessibility and regenerative abilities.

A unique hair tumor with a rippled pattern was identified, showing incomplete differentiation and unusual cell arrangements.

Certain substances can help skin cells become anti-inflammatory, aiding in tissue repair.

Merkel cell increase is specific to certain skin diseases, not general skin growth.

Intravital imaging helps us better understand stem cells in their natural environment and could improve knowledge of organ regeneration and cancer development.

Newly born mesenchymal cells quickly spread out in response to tissue tension during early development.

Hair follicle dermal stem cells help control hair growth timing by regulating signals at the hair germ–dermal papilla interface.

A new imaging technique can observe stem cells in living mice without harming them.

EPI-NCSCs from hair follicles may help treat brain development issues in mice.

Hair follicle cells can create new blood vessels in the skin.

New mouse models help study melanocytic cells for melanoma research.

Integrin-linked kinase is crucial for melanoblasts to properly colonize the skin.

Stem cells in developing hair follicles move to specific areas as they mature.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.
