The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Fish teeth and taste bud densities are linked and can change between types due to shared genetic and molecular factors.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

Blocking Wnt/β-catenin signaling with EGF receptor is necessary for proper hair growth.

Stem cell niches are crucial for regulating stem cell renewal and differentiation, and understanding them can help in developing regenerative therapies.

Baby teeth stem cells can potentially grow organs and treat diseases.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Micrografts are useful for healing wounds, regenerating bone and periodontal tissues, and improving hair transplantation outcomes.

NFIC helps human dental stem cells grow and become tooth-like cells.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

Mitochondrial problems in tooth cells lead to bad enamel and dentin development in mice.

Removing Mediator 1 from certain mouse cells causes teeth to grow hair instead of enamel.

Msx and Dlx genes are crucial for development, controlling cell behaviors like growth and differentiation through their roles as gene regulators.

Ectodysplasin signaling is crucial for skin appendage development, requiring specific doses and durations.

NFIC helps rat dental cells grow and turn into bone-like cells.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Hair follicle stem cells are promising for wound healing but require more research for safe clinical use.

Scientists can now create skin with hair by reprogramming cells in wounds.

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

Newly divided skin cells quickly move to join skin structures due to tissue tension and specific signals.

Newly born mesenchymal cells quickly spread out in response to tissue tension during early development.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

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.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.
