Cell size controls when stem cells divide.

Deleting Smad4 and PTEN genes in mice causes rapid, invasive forestomach cancer.

Deleting Smad4 and PTEN genes in mice causes rapid, invasive stomach cancer.

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

Researchers developed a new method to quickly prepare skin cells that improve wound healing in rats.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

The study maps how genes are regulated during mouse hair growth.

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

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

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.

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

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

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

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

Stem cells and their surrounding environment in hair follicles work closely together, affecting hair growth and having implications for cancer and tissue regeneration.

Stem cell treatments may improve burn wound healing.

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

Understanding hair follicle biology and stem cell control could lead to new hair loss treatments.

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.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

Apoptosis may contribute to hair loss in androgenetic alopecia.

Excess maternal androgens can cause heart problems in offspring.
