Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

The document concludes that understanding health requires considering evolutionary perspectives on reproductive fitness, and recognizing the complexity of factors like diet, testosterone, and sexual orientation.

Scientists developed tools to observe hair regeneration in real time and assess skin health, using glowing mice and light-controlled genes.

Eating flaxseed made rabbit hair longer and thicker and improved their weight and blood sugar and cholesterol levels.

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.

Herman Bierens had a successful career in econometrics, contributed to education, and plans to continue research after retirement.

Understanding skin patterns can help us learn about skin diseases and their treatments.

Male pattern hair loss may have evolved to promote younger fathers for offspring health and survival, encouraging monogamy and paternal nurturing.

Genetic manipulations that extend lifespan in mice may not work as effectively in humans.

The environment around the time of conception can change the VTRNA2-1 gene in a way that lasts for years and may affect disease risk.

Feather patterns form through genetic and epigenetic controls, with cells self-organizing into periodic patterns.

Hair patterns in mice are controlled by both a global system dependent on Fz6 and a local self-organizing system.

Mutations in the NR3C1 gene cause a rare condition that affects hormone signaling and can lead to various symptoms, with dexamethasone as a treatment option.

Fibroblast growth factors are crucial for hair follicle development and regeneration.

Phosphorylation controls TFEB's location in the cell, affecting cell metabolism and stress response.

Different treatments for Hidradenitis suppurativa range from antibiotics and hormonal therapies to surgery, depending on severity.

Researchers found that certain RNA circles in the brain are linked to disease risk, but their exact role in disease is still unknown.

Tissue-specific variation in mutant load complicates genetic counseling and prenatal diagnosis.

Fibrodysplasia ossificans progressiva is a rare genetic disorder that causes extra bone growth and symptoms of premature aging.

The model accurately predicts age from saliva and buccal cells for forensic use.

A new model can predict drug-disease links well, helping drug research.

Genetic defects in the glucocorticoid receptor gene can cause conditions with abnormal sensitivity to stress hormones, and other factors may also affect this sensitivity.

Key genes crucial for sheep hair follicle development were identified, aiding fine wool breeding and human hair loss research.

The method effectively identifies and measures seven banned substances in cosmetics.

A specific group of skin stem cells was found to help maintain hair follicle cells.

Different genes are active in dogs' hair growth and skin, similar to humans, which helps understand dog skin and hair diseases and can relate to human conditions.

A protein called sFRP4 can slow down hair regrowth.

The model showed that immune system guardians and the cytokine interferon-γ are key in alopecia areata progression.

The model shows that filament flexibility and amino acid differences affect how fast intermediate filament proteins assemble.

Melanin absorbing light is necessary but not enough for effective hair removal by light treatment.
