Glossary Hemidesmosomes

specialized structures anchoring cells to basement membranes

Hemidesmosomes are specialized structures that anchor cells to the underlying basement membrane, providing stability and support. They play a crucial role in maintaining the integrity of tissues, especially in areas subject to mechanical stress, such as the skin and hair follicles.

research Wnt/β-Catenin Signaling Stabilizes Hemidesmosomes in Keratinocytes

5 citations , November 2021 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that inhibiting Wnt/β-catenin signaling disrupted hemidesmosome organization in keratinocytes, suggesting potential therapeutic targets for HD-defective diseases like epidermolysis bullosa.

research SCD1 Sustains Homeostasis of Bulge Niche via Maintaining Hemidesmosomes in Basal Keratinocytes

4 citations , December 2022 in “Advanced science”

This study found that fatty acid desaturation regulated by SCD1 is crucial for hair growth by maintaining hair follicle stem cell niches, with its absence causing abnormal hair growth in mice.

research Hemidesmosomes and Notch signaling regulate epidermal differentiation via delamination

April 2026 in “Development”

This study found that loss of integrin-β4 or its ligand, laminin-α3β3ɣ2, in keratinocytes increases differentiation via delamination, and demonstrated a role for hemidesmosomes in epidermal differentiation through both mitotic and non-mitotic mechanisms, influenced by Notch signaling.

research Stabilization of Hemidesmosomal Proteins: A Possible Key Contributor to Wnt/β-Catenin Pathway Action in the Skin

December 2021 in “Journal of Investigative Dermatology”

This study reports that inhibition of Wnt/β-catenin signaling disrupts hemidesmosome organization in keratinocytes by altering the localization of components like plectin and collagen XVII.

research Evidence that Myc activation depletes the epidermal stem cell compartment by modulating adhesive interactions with the local microenvironment

182 citations , May 2003 in “Development”

This study found that Myc activation in mouse epidermis impairs keratinocyte adhesion and motility by downregulating extracellular matrix and cytoskeleton proteins, affecting hair lineage differentiation.
