Alk1 in specific cells is crucial for proper nerve branching and hair function.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

Scientists created 3D hair-like structures that could help study hair growth and test treatments.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

A gene variant causes patched hair loss in mice, similar to alopecia areata in humans.

NIR-II imaging effectively tracked stem cells that helped repair facial nerve defects in rats.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Reflectance confocal microscopy is useful for diagnosing and monitoring skin diseases, but it has limitations and requires expertise for correct use.

3D imaging shows clearer details of skin structure changes with age.

The conclusion is that accurately replicating the complexity of the extracellular matrix in the lab is crucial for creating realistic human tissue models.

Rare ULBP3 gene changes may raise the risk of Alopecia areata, a certain FAS gene deletion could cause a dysfunctional protein in an immune disorder, and having one copy of a specific genetic deletion is okay, but two copies cause sickle cell disease.

Many patients experience long-lasting symptoms like fatigue and pain after COVID-19, regardless of initial disease severity.

Different small areas within hair follicles send specific signals that control what type of cells stem cells become.

Zebrafish are useful for studying and developing treatments for human skin diseases.

The medicine baricitinib was found to notably improve hair regrowth in alopecia areata, but more research is needed on its side effects and other treatments.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Keratinocytes and adipose-derived stem cells can effectively heal difficult skin wounds.

Patients treated in Respiratory Intensive Care Units for COVID-19 are more likely to get mood disorders than those in other care settings.
