Exosomal miRNAs from stem cells can help improve skin health and delay aging.

Syndecan-1 is essential for maintaining skin fat and preventing cold stress.

SARMs may be an effective treatment for a certain type of breast cancer by blocking cancer growth and spread.

Myristoleic acid helps hair growth by boosting cell growth and recycling processes in hair follicle cells.

Increasing PBX1 reduces aging and cell death in hair follicle stem cells by boosting SIRT1 and lowering PARP1 activity.

The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
