The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.

The skin is a complex barrier that protects the body, regulates temperature, and helps with immune responses.

iPSC-derived stem cells on a special membrane can help repair full-thickness skin defects.

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

Different small areas within hair follicles send specific signals that control what type of cells stem cells become.

Folliculin deficiency causes problems with cell division and positioning due to disrupted RhoA signaling and interaction with p0071.

Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.

M-CSF-stimulated myeloid cells can turn into skin cells and help heal wounds and regrow hair.

Improving skin barrier and using antifungal treatments can help manage dandruff.

The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

Keeping β-catenin levels high in mammary cells disrupts their development and branching.

Claudin-1 is important for the barrier function and growth of hair.

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

Scientists created a lab-grown hair follicle model that behaves like real hair and could improve hair loss treatment research.

A virus protein can activate a pathway that may lead to abnormal hair follicle development.

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.

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.

New skin substitutes for treating severe burns and chronic wounds are being developed, but a permanent solution for deep wounds is not yet available commercially.

GMG-43AC may help reduce unwanted hair growth and treat certain hair loss conditions.

Older people's sweat glands are less effective at helping skin wounds heal due to weaker cell connections.

Stem cells can help regenerate hair follicles.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.

Mice can regrow hair on wounds due to specific cell interactions and mechanical forces not seen in rats.

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.

Dermal Wnt/β-catenin signaling is important for the proper size and development of hair follicles.

Valentina Greco's research shows that the environment around hair follicle stem cells is more crucial for regeneration than the stem cells themselves.

Wound healing is a complex process involving different cells and stages, leading to scar tissue formation and strength increase over time.

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

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

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