Sensory neuron changes and Merkel-cell changes in the skin happen independently during normal skin maintenance.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Hair follicle cells change their DNA packaging during growth cycles and when grown in the lab.

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.

The mTurq2-Col4a1 mouse model shows that cells can divide while attached to stable basement membranes during development.

Melanoblasts migrate to the skin using various pathways, and understanding this process could help with skin disease research.

The study found that certain genes are important for hedgehog skin appendage development and immunity, with spines possibly evolving for protection and infection resistance.

Basement membrane changes are crucial for hair follicle development.

Gremlin proteins help regulate hair growth by balancing signals in hair follicles.

A 4kb fragment of the desmocollin 3 promoter targets gene expression to specific skin and hair follicle areas.

The skin basement membrane is specialized for different tissue interactions, important for hair growth and attachment.

Translation levels actively determine keratinocyte cell fate.

lncRNAs play a key role in hair follicle development, affecting cashmere quality and yield.

Neonatal blood vessels rearrange and stabilize as adults, with adult vessels better at self-repair after injury.

STAT5 and Sox18 are crucial for hair growth and wound healing.

Mouse skin has special cells in the epidermis that decrease with age and are linked to keratinocyte stem cells.

Lymphoid-specific helicase (Lsh) is crucial for skin growth, change, and healing after injury.

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

MiR-23b and miR-133 affect sheep hair growth by targeting specific genes.

The document concludes that careful design of genetic fate mapping experiments is crucial for accurate cell lineage tracing in mice.

Atoh1 expression can create new Merkel cells in the skin.

The research shows that skin cancer likely originates from hair follicles and that certain cell populations expand to promote skin cancer growth.

The enzymes Tet2 and Tet3 are important for skin cell development and hair growth.

Wnt-10b helps skin cells and hair grow.

Keratin K14 expression varies between hair follicles and epidermis, affecting cell differentiation.

Corneal cells can transform into hair-producing skin cells when exposed to certain signals.

Less stiff collagen promotes higher cell growth in hair follicles.

Key genes and RNAs related to hair growth in sheep were identified, aiding future breeding improvements.

Regulatory T cells adapt to different environments to control inflammation and support tissue repair.
