Hair can naturally regain color after greying, and this change may be linked to stress levels.

Researchers successfully grew hair follicle stem cells from mice and humans, which could be useful for tissue engineering and regenerative medicine.

Liver stem cells keep their basic functions even in inflamed liver tissue.

Hair can naturally regain color, and stress might influence greying and its reversal.

The study identifies four distinct zones in the fetal vaginal epithelium, enhancing understanding for potential applications in women's health.

Age-related hearing loss involves cochlear damage and metabolic changes.

RAGE is a potential target for melanoma treatment, but its effectiveness is uncertain due to variable expression levels.

SCUBE3 is a potential target for cancer and alopecia treatment but is challenging to target due to its varied roles.

Controlling cellular changes can enable safe rejuvenation without cancer risk.

Removing senescent cells can improve hair growth and regeneration.

Mesenchymal stem cells could help treat aging-related diseases better than current methods.

Low selenium levels can extend lifespan but worsen health issues.

SCDSFs from zebrafish embryos are beneficial for treating cancer, regenerating tissues, and improving conditions like psoriasis and alopecia.

RCS-01 therapy is safe and may improve skin structure by affecting gene expression.

Different lab conditions and light treatment methods change how human skin cells respond to light therapy.

The TCL1 transgenic mouse model is useful for understanding human B-cell leukemia and testing new treatments.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Embryonic and adult stem cells are valuable for improving skin grafts and cell therapy.

Cell size controls when stem cells divide.

Different types of stem cells in the skin contribute to the variety of melanoma forms.

Removing the ATR gene in adult mice causes rapid aging and stem cell loss.

Understanding how mesenchymal stem cells stay undifferentiated can improve their use in treating diseases.

Using radiation to make mice's hair turn gray helps study and find ways to prevent or reverse hair graying.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Eating fewer calories improves the ability of stem cells to repair and renew the body in various tissues.

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.

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.

Different types of skin cells play specific roles in development, healing, and cancer.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.
