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.

MSC-derived exosomes can help treat COVID-19, hair loss, skin aging, and arthritis.

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

Fat tissue cells are a promising option for healing various diseases, but more research is needed to ensure they are safe and effective.

An imbalance between certain immune cells is linked to a chronic skin condition and may be influenced by obesity, smoking, and autoimmune issues.

Fat from the body can help improve hair growth and scars when used in skin treatments.

ADSC-CE treatment safely increases hair density and thickness in androgenetic alopecia patients.

Linoleic acid from Malva verticillata seeds may help treat hair loss by promoting hair cell growth and blocking baldness signals.

Umbilical cord-derived media is safe and effective for hair growth.

Distinct β-catenin patterns are linked to cell growth, not cell death, in lung cancer.

PDGF signaling is crucial for maintaining and renewing hair follicle stem cells, which could help treat hair loss.

Vav2 and Vav3 proteins help control skin stem cell numbers and activity in both healthy and cancerous cells.

In June 2019, the stem cell research field saw major progress, including new clinical trials, FDA approvals, and industry collaborations.

The study created a test that found hormonal and toxic effects in plant and fungal extracts using prostate cancer cells.

The new compound was more effective than finasteride in reducing markers of hair loss and prostate issues in cell tests.

A protein called EGFR protects hair follicle stem cells, and when it's disrupted, hair follicles can be damaged, but blocking certain pathways can restore hair growth.

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

Small molecule IM boosts hair growth by changing stem cell metabolism.

Eclipta alba extract may help treat obesity by blocking fat cell formation and lowering blood lipid levels.

Recombinant keratin materials may better promote skin cell differentiation than natural keratin.

Eating less can improve stem cell function and increase lifespan.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

The conclusion is that the nuclear lamina and LINC complex in skin cells respond to mechanical signals, affecting gene expression and cell differentiation, which is important for skin health and can impact skin diseases.

Hormones, especially testosterone and DHT, are key for penis development and function, and testosterone therapy may help with erectile dysfunction in those with low levels.

Increased cell death and reduced cell growth in hair follicles contribute to baldness.

Biomaterials with MSC-derived substances could improve tissue repair and have advantages over direct cell therapy.

5-alpha-reductase inhibitors may cause a low incidence of erectile dysfunction that decreases over time.

Betacoronaviruses, like COVID-19, may cause hormone system dysfunction and affect disease susceptibility and severity.

FoxN1 overexpression in young mice harms immune cell and skin development.

Men using hair loss drugs like finasteride may experience sexual side effects like erectile dysfunction, but it's unclear who will be affected and when. Treating depression and sexual symptoms is suggested, as these men often have higher rates of both. More research is needed to understand why these side effects occur.
