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

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.

Hair grows when stem cell offspring in the follicle base proliferate, influenced by the dermal papilla.

High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.

Meis1 is crucial for skin health and tumor development.

Certain proteins help nerve cells branch, and other findings relate to cancer, stem cell behavior, and cell division.

Curly and straight hair differ in how their internal fibers are arranged.

The study introduced a new imaging technology to track skin healing and bone marrow cell activity over time.

Certain genes and pathways are linked to the production of finer and denser wool in Hetian sheep.

3D imaging of skin biopsies offers better accuracy but is time-consuming and can't clear melanin.

Wrightia tinctoria extract may promote hair growth better than minoxidil.

Better diagnosis and control of thallium poisoning are needed to prevent severe outcomes.

Minoxidil lotion may harm male reproductive health.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

Mint essential oils can kill parasites that cause cystic echinococcosis, with M. pulegium oil being more effective than M. piperita oil.

Short-term finasteride treatment may lower some cell death factors in prostate cancer cells.

Scientists created iodinated arylhydantoins and arylthiohydantoins that could potentially be used for imaging prostate cancer. Some versions with specific side-chains showed high potential for this use.

Targeted therapies for lung cancer are effective but require careful management of side effects to benefit patients.

A standard protocol for alopecia areata clinical trials was created to improve consistency and encourage more research.

Stem cell research and regenerative medicine have made significant advancements in treating various diseases and conditions.

Hair properties change under electromagnetic fields and are influenced by individual characteristics and the environment.

Zinc oxide nanoparticles in sunscreen do not penetrate deep into the skin.

Photographic documentation crucial for evaluating hair growth in androgenetic alopecia.

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

Lamins are vital for cell survival, organ development, and preventing premature aging.

PI3K/Akt pathway is crucial for hair growth and regeneration.

Taking spironolactone and linestrenol for androgen excess can lead to lower bone density in young women.

Women with hyperandrogenic amenorrhea have similar bone density to healthy women but lower than androgenized women without amenorrhea, and high DHEAS levels might affect bone density.

The androgen receptor is a promising target for breast cancer treatment, especially in triple-negative cases, but more research is needed for personalized therapies.
