Excess vitamin A changes skin and hair follicle development and affects polysaccharide distribution.

Treatment reduced cystic lesions but didn't change existing Nevus Comedonicus.

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.

Cicatricial alopecia may be caused by immune attacks on hair follicles, gland issues, or stem cell damage.

The human keratin 6a gene's specific sequences trigger expression in skin layers after injury.

Hair follicle stem cells help maintain skin health by moving to and supporting the skin's surface layers.

Researchers created a potential skin substitute using a biodegradable mat that supports skin cell growth and layer formation.

Hair follicle development involves complex interactions between skin layers and cells, but many details are still unknown.

Keratinocytes from dog hair follicles can create a functional skin layer in a lab model, useful for dog skin therapy.

Nevoid basal cell carcinomas start in the skin's top layer and hair follicles.

Sciellin is a protein that helps form protective layers in skin, hair, and nails.

The skin and thymus develop similarly to protect and support immunity.

FGF-9 speeds up the early development of certain organs, showing potential for organ regeneration.

Using a collagen sponge scaffold helps stem cells become more like skin cells.

Mitochondrial problems in tooth cells lead to bad enamel and dentin development in mice.

Electrospun matrices help regenerate skin and hair follicles using PCL and collagen scaffolds.

Corneal cells can transform into skin and hair cells through specific signals.

Fos protein is crucial for cell transition to cornification in keratinized tissues.

Epimorphin, a protein, plays a key role in the development of hair follicles in human fetuses, but it doesn't help in maintaining the stem cell population of the follicular skin layer.

CO₂ laser surgery successfully healed a dog's chronic paw condition.

Pax9 is crucial for proper tongue surface development and preventing skin-like changes.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

A new pair of mouse keratins, 65 kD and 48 kD, are found in specific skin areas and are linked to a unique skin differentiation type.
