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

Understanding different types of skin cells, especially fibroblasts, can lead to better treatments for wound healing and less scarring.

Different types of stem cells and their environments are key to skin repair and maintenance.

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.

Wnt signaling is crucial for skin development and hair growth.

NK cells play a role in skin diseases like eczema and psoriasis.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

The FOXN1 gene is crucial for developing immune cells and preventing immune disorders.

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Beard cells, unlike scalp cells, produce growth factors in response to testosterone, which may explain differences in hair growth.

Possible new treatments for common hair loss include drugs, stem cells, and improved transplants.

Stem cells, especially from fat tissue and Wharton's jelly, can potentially regenerate hair follicles and treat hair loss, but more research is needed to perfect the treatment.

Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.

TGFβ signaling prevents sebaceous gland cells from producing fats.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

Further research is needed to improve hair regeneration using stem cells and nanomaterials.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

The shape of fibrous scaffolds can improve how stem cells help heal skin.

The hydrogels help harvest cells while preserving their mechanical memory, which could improve wound healing.

Foxp1 helps control hair stem cell growth and response to stress during hair growth cycles.

Different human hair follicle stem cells grow at different rates and respond differently to a baldness-related compound.

Gelatin microspheres with stem cells speed up healing in diabetic wounds.

New method uses hair follicle cells to estimate human body clock phase, potentially improving sleep disorder diagnosis.

Increasing alkaline phosphatase in human skin cells helps to grow more hair.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

Bone marrow-derived stem cells improved healing and reduced scarring in second-degree burns in rats.

N-acetyl-L-cysteine (NAC) can prevent DNA damage and protect cells from harm.
