Eating less can improve stem cell function and increase lifespan.

Better hair loss models needed for research.

MSCs help rejuvenate skin by promoting cell growth and reducing inflammation.

Rhizobacterial strain RT3 helps lettuce survive drought by producing protective substances like proline.

Higher testosterone harms sperm motility, while higher estradiol improves sperm survival.

The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.

Skin may help in getting rid of excess iron through the process of skin cell renewal.

Frog skin cells need the protein desmoplakin for proper development and cell layer formation.

Researchers fixed gene mutations causing a skin disease in stem cells, which then improved skin grafts in mice.

Double-stranded RNA helps regenerate hair follicles by increasing retinoic acid production and signaling.

Certain cells outside the hair follicle's bulge area can quickly regenerate damaged hair follicles, potentially helping to reduce hair loss from cancer treatments.

Alisertib was found to be an effective and tolerable treatment for children with recurrent brain tumors.

Ginsenoside Rb1 from Panax ginseng helps mink hair grow by activating certain cell signals.

The metoprolol-spironolactone combination improves heart function in patients with coronary heart disease and heart failure.

Neural progenitor cell-derived nanovesicles help hair growth by activating a key signaling pathway.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

Understanding developmental pathways can improve wound healing treatments.

The Rotterdam Study updated findings on elderly health, focusing on heart disease, genetics, lifestyle effects, and disease understanding.

Stem cell-derived conditioned medium shows promise for treating various medical conditions but requires standardized production and further validation.

High levels of male hormones, insulin resistance, and obesity are closely linked and worsen polycystic ovary syndrome, but more research is needed to improve treatments.

Hair follicle stem cells use specific chromatin changes to control their growth and differentiation.

Researchers created human hair follicles using a new method that could help treat hair loss.

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

Low oxygen conditions increase the hair-growing effects of substances from fat-derived stem cells by boosting growth factor release.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.

A certain smell receptor in hair follicles can affect hair growth when activated by a synthetic sandalwood scent.

Mice without the Sept4/ARTS gene heal wounds better due to more stem cells that don't die easily.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.
