Steroid sex hormones activate matriptase in prostate cancer cells but not in breast cancer cells.

Reflectance spectroscopy can noninvasively track hair growth stages by measuring skin reflectance and melanin changes.

Hormone treatment for transsexual individuals is effective but carries risks like thromboembolic events and mood changes, with most side effects being minor and reversible.

Obesity leads to physical, metabolic, reproductive issues, higher healthcare costs, and mental health problems.

Chitosan, a natural substance, can be used to create tiny particles that effectively deliver various types of drugs, but more work is needed to improve stability and control of drug release.

BMP signaling is essential for the development of touch domes.

Autofluorescence can sort plant cells without labeling.

Mutant cells in hair follicles are influenced by their location and interactions with surrounding cells.

Stem cells control their future role by changing ERK signal timing, affecting tissue regeneration and cancer.

The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.

The Kras mutation changes normal cell signals, leading to disrupted tissue structure and potential cancer.

Stem cells and their surrounding environment in hair follicles work closely together, affecting hair growth and having implications for cancer and tissue regeneration.

Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.

The author felt excited and honored to receive the 2016 Early Career Life Scientist Award.

Valentina Greco emphasizes the importance of combining business management with mentoring to run a successful academic lab.

STIM1 is essential for sweat secretion.

Stem cells are key for the growth, upkeep, and repair of sebaceous glands and for understanding skin disorders.

People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.

Smad2/3-dependent TGF-β signaling increases during wound healing.

The keratin network in mouse skin changes during cornification and affects the skin's protective barrier.

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.

The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Intravital imaging helps us better understand stem cells in their natural environment and could improve knowledge of organ regeneration and cancer development.

Diamond nanoparticles can penetrate skin and reach hair follicles, useful for imaging applications.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Exosomes show promise for tissue repair and regeneration with advantages over traditional cell therapies.

Newly born mesenchymal cells quickly spread out in response to tissue tension during early development.

The mTurq2-Col4a1 mouse model shows how the basement membrane develops in live mammals.
