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

Male infertility and genitourinary birth defects are often linked to genetic issues.

A unique skin cell similar to hair bulb melanocytes was identified, with better preservation using permanganate fixation.

Epidermal stem cells are in hair follicle bulge regions, and isolation and culture methods are effective.

The study concludes that as skin matures from infancy to childhood, there are major changes in cell differentiation, stemness, and growth, leading to a stronger skin barrier in older children.

Desmocollin 1 and 3 have distinct patterns in human tissues, with Dsc1 in specific skin and hair layers and Dsc3 in various epithelial layers.

The upper hair follicle is stable, while the lower part allows movement during hair growth.

Hair medullary cells in mammals vary in complexity, with humans having more structured cells similar to inner root sheath cells.

Different tissues in cows have different types of cytokeratins.

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

Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.

Cell junctions are crucial for healthy skin by supporting sebaceous gland function and sebum production.

EGF and EGFR are essential for goat fetal skin development.

Sertoli cell transplants can reduce inflammation and improve sperm quality.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Polycomb Repressive Complex 1 is crucial for keeping stem cells stable and maintaining healthy adult tissues.

Wool follicle cells are more complex than previously thought.

A nonviral method was developed to label and culture human hair follicle stem cells.

Adult rat olfactory mucosa has stem cells that can self-renew and become different cell types.

Mongolian gerbils heal wounds differently than mice, with unique protein levels and gene expression that affect skin repair.

Exposure to low doses of finasteride in the womb causes changes in the prostate of both male and female gerbils.

Researchers found that bulge cells from human hair can grow quickly in culture and have properties of hair follicle stem cells, which could be useful for skin treatments.

Scientists created three types of structures to help regrow hair follicles, and all showed promising results for hair regeneration.

Lower proximal cup cells, not bulge stem cells, regenerate hair follicles after chemotherapy.

Sebum production in sebaceous glands is similar to hair growth, involving cell development and degeneration.

Epiprofin helps cells grow in developing teeth, hair, and limbs.

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

Hair follicle stem cells can become corneal-like cells with the help of pax6.

The new method showed that endometriotic tissue has lower estrogen receptor levels but similar progesterone levels compared to normal endometrium, with both following a similar cycle.
