PGD2 stops hair growth and is higher in bald men with AGA.

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

Lactate production is important for activating hair growth stem cells.

The PDGF/PDGFR pathway is a potential drug target with mixed success in treating various diseases, including some cancers and fibrosis.

Jumonji genes are important for development and their mutations can cause abnormalities, especially in the heart and brain.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

Blood vessels and specific genes help turn cartilage into bone when bones heal.

Blocking JAK-STAT signaling can lead to hair growth.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

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

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

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

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

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.

Fat cells in the skin help start healing and form important repair cells after injury.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

FGF signaling is a promising target for developing treatments for wounds, metabolic diseases, and cancer.

Thymus transplantation successfully restored immune function in infants with FOXN1 deficiency.

A mother's PPARγ is crucial for preventing harmful milk that can cause inflammation and growth problems in babies.

Scientists turned mouse stem cells into skin cells that can grow into skin layers and structures.

No treatment fully prevents hair loss from chemotherapy yet.

Low-oxygen conditions and ECM degradation products increase the healing abilities of perivascular stem cells.

Growth factors are crucial for hair development and could help treat hair diseases.

The document concludes that early diagnosis and treatment of Congenital Adrenal Hyperplasia are crucial for preventing serious health issues and improving patient outcomes.

Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.

FOXO1 is important for wound healing, but its dysfunction in diabetes can slow the healing process.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.
