Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

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 fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

The study introduced a new imaging technology to track skin healing and bone marrow cell activity over time.

Epidermal stem cells have potential for personalized regenerative medicine but need careful handling to avoid cancer.

Stem cells rearrangement regenerates functional hair follicles, potentially treating hair loss.

The engineered skin substitute helped grow skin with hair on mice.

Using gelatin sponges for deep skin wounds helps bone marrow cells repair tissue without scarring.

Mesenchymal stem cells show promise for treating various skin conditions and may help regenerate hair.

Signals from skin cells controlled by Rac proteins help turn certain precursor cells into white fat cells.

Skin spheroids with both outer and inner layers are key for regrowing skin patterns and hair.

Injecting a person's own fat stem cells into their skin can make it look younger and improve double eyelids for over a year.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

Hair follicles help attract immune cells to the skin during stress.

Blocking β-catenin in skin cells improves hair growth during wound healing.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Different types of stem cells help maintain and heal skin.

CYP2B12 enzyme in skin cells converts arachidonic acid into specific bioactive lipids.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

The skin's basement membrane has specialized structures and molecules for different tissue interactions, important for hair growth and attachment.

Ruxolitinib helps protect skin stem cells and keeps skin healthy in mice with skin GVHD.

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

Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.
