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

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

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.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Muscles and nerves that cause goosebumps also help control hair growth.

The HR protein's role as a repressor is essential for controlling hair growth.

The study found that immune responses disrupt hair growth cycles, causing hair loss in alopecia areata.

IGF-1 injections help mice grow more hair by increasing cell growth and blocking a hair growth inhibitor.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

RACB in barley is crucial for cell polarity and nucleus positioning, aiding fungal infection.

Fetal cells could improve skin repair with minimal scarring and are a potential ready-to-use solution for tissue engineering.

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

The document concludes that understanding hair follicle cell cycles is crucial for hair growth and alopecia research, and recommends specific techniques and future research directions.

Using a special stem cell formula on the scalp once a month for six months helped people with hair loss grow more hair.

CIP/KIP proteins help stop cell division and support hair growth.

The document concludes that understanding how adult stem and progenitor cells move is crucial for tissue repair and developing cell therapies.

The hydrogels help harvest cells while preserving their mechanical memory, which could improve wound healing.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Cell therapy shows promise for treating severe psoriasis but needs more research to confirm safety and effectiveness.

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

Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.

Tiny natural vesicles from cells might help treat hair loss.

PRP therapy and minoxidil combo works best for male hair loss.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

Rat whisker cells can help turn other cells into nerve cells and might be used to treat brain injuries or diseases.
