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

The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.

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

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

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.

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.

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

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.

Tiny natural vesicles from cells might help treat hair loss.

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.

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.

New insights into cell communication in psoriasis suggest innovative drug treatments.

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

Increasing Rps14 helps grow more inner ear cells and repair hearing cells in baby mice.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.
