Studysummary This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

Research cited in this study

13 / 13 results

research Hairy Tale of Signaling in Hair Follicle Development and Cycling

161 citations , August 2012 in “Seminars in cell & developmental biology”

This review discusses the molecular mechanisms involved in hair follicle development and regeneration, highlighting findings from mouse genetic studies, and reports no new experimental results.

research Shh Maintains Dermal Papilla Identity and Hair Morphogenesis via a Noggin–Shh Regulatory Loop

138 citations , June 2012 in “Genes & Development”

This study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.

research Multiple Roles of Integrin-Linked Kinase in Epidermal Development, Maturation, and Pigmentation Revealed by Molecular Profiling

9 citations , May 2012 in “PLOS ONE”

This study found that integrin-linked kinase is crucial for various epidermal functions, including differentiation and barrier formation, and also plays a previously unreported role in melanocyte development and function.

research Emerging Role of ILK and ELMO2 in the Integration of Adhesion and Migration Pathways

10 citations , May 2012 in “Cell Adhesion & Migration”

This study found that ILK/ELMO2 complexes in epidermal keratinocytes are selectively activated by epidermal growth factor to induce cell migration, unlike with other growth factors.

research Targeted Inactivation of Integrin-Linked Kinase in Hair Follicle Stem Cells Reveals an Important Modulatory Role in Skin Repair After Injury

22 citations , May 2011 in “Molecular Biology of the Cell”

In this study, gene inactivation in mouse hair follicle stem cells lacking ILK impaired wound healing by reducing their progeny’s contribution to the regenerating epidermis, but did not affect hair follicle regeneration.

research Review of Hair Follicle Dermal Cells

321 citations , December 2009 in “Journal of Dermatological Science”

This review discusses the role of dermal cells in hair follicle regeneration and morphogenesis and highlights their potential therapeutic implications, but it reports no new empirical findings.

research Epidermal Patterning and Induction of Different Hair Types During Mouse Embryonic Development

81 citations , September 2009 in “Birth defects research”

This review discusses the mechanisms behind hair patterning during mouse embryonic development and reports no new experimental findings.

research Genetic Interplays Between Msx2 And Foxn1 Are Required For Notch1 Expression And Hair Shaft Differentiation

67 citations , December 2008 in “Developmental Biology”

This study found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

research Dlx3 Is a Crucial Regulator of Hair Follicle Differentiation and Cycling

132 citations , August 2008 in “Development”

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.
