Hox proteins help maintain keratinocyte identity by regulating miRNA expression.

MEX3A is crucial for maintaining intestinal stem cells in mice.

A rare ovarian tumor caused early puberty signs in a 1-year-old girl, but surgery reduced hormone levels.

Trichohyalin is also found in the outer layers of normal human skin.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

Matriptase is crucial for keeping epithelial tissues healthy and functioning properly.

HBCs in the olfactory epithelium can self-renew or differentiate into other cell types, with specific patterns during regeneration.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

The cornified envelope is crucial for skin's barrier function and involves key proteins and genetic factors.

Keratin 79 marks a new group of cells that are key for creating and repairing the hair follicle's structure.

Hair follicle stem cells can generate all hair cell types, skin, and sebaceous glands.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

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

Epidermal keratinocytes start wound healing and inflammation after schistosome infection.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

K15 gene is mainly active in the basal layers of hair follicles and epithelia, aiding early skin cell development.

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

Meibomian glands are like hair follicles without a hair shaft.

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

Lymph vessels in airways vary by location, with the most in the upper pharynx and changes after birth.

Apocrine type cutaneous mixed tumors often resemble hair follicles, sebaceous glands, and apocrine glands.

Hair growth is driven by cells that move and change like a conveyor belt.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Stem cell behavior varies with stimuli, and lineage changes can happen without affecting stem cell division.
