Lanceolate complexes in mouse hair follicles are essential for touch and depend on specific cells for maintenance and regeneration.

Sox21 is crucial for tooth development and enamel formation by preventing cells from changing into a different type.

Hair loss caused by genetics and hormones; more research needed for treatments.

Skin has specialized touch receptors that can tell different sensations apart.

Wounds on the face usually heal with scars, but understanding how some wounds heal without scars could lead to better treatments.

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

Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.

AP-2α and AP-2β proteins are essential for healthy adult skin and hair.

The androgen receptor is a promising target for breast cancer treatment, especially in triple-negative cases, but more research is needed for personalized therapies.

Dermal cells are key in controlling hair growth and could potentially be used in hair loss treatments, but more research is needed to improve hair regeneration methods.

The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.

Eyelid cells share signaling components but differ in pathway activity.

Environmental pollutants can damage hair health and cause hair loss.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

Epidermal stem cells create and maintain skin structures like hair and nails through specific signaling pathways and vary by location and function.

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

Skin stem cells can help improve skin repair and regeneration.

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

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.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Treating fat stem cells with low oxygen boosts hair growth cell growth through specific signaling pathways.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

Alternative treatments show promise for hair growth beyond traditional methods.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

Different types of fibroblasts play various roles in diseases and healing, and more research on them could improve treatments.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

Dogs could be good models for studying human hair growth and hair loss.

MicroRNAs are crucial for controlling skin development and healing by regulating genes.
