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

Human hair follicle dermal cells can effectively replace other cells in engineered skin.

Skin lesions in Carney complex are likely caused by a specific group of skin cells that promote pigment production due to a genetic mutation.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Two microRNAs affect hair follicle development in sheep by targeting specific genes.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

Signals from skin cells controlled by Rac proteins help turn certain precursor cells into white fat cells.

The study provides insights into hair growth mechanisms in yaks.

The guide explains how to study human skin fat cells and their tissue, aiming to improve research and medical treatments.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

Skin fat helps with body temperature control and has other active roles in health.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

A specific group of skin stem cells was found to help maintain hair follicle cells.

The research found a way to identify and study skin cells with stem cell traits, revealing they behave differently in culture and questioning current stemness assessment methods.

Immune cells are essential for early hair and skin development and healing.

Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Exosomes can improve skin health and offer new treatments for skin repair and rejuvenation.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.

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.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

Freezing gamma-irradiated amniotic fluid may help hair growth and speed up the growth phase.

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

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

The conclusion is that CD90 is not a specific marker for fibroblast subtypes and better methods are needed to identify them.

Skin organoids are a promising new model for studying human skin development and testing treatments.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.
