Genetic Basis of Skin Appendage Development

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This study found that WNT signaling is essential for the initiation of mammary gland morphogenesis in embryonic mice, promoting placode development and potentially playing a critical role in skin appendage formation.

This study found that FGF signaling is necessary for the initiation of feather placode development in chicken embryos, with FGF10 being implicated as an early dermal signal in the process.

This study found that BMP receptor IA is crucial for hair progenitor cell differentiation in mice, and its sequential inhibition and activation are necessary to generate a functioning hair shaft.

Ectodysplasin-A1 is crucial for developing hair, teeth, and glands.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This review summarizes recent advances in understanding the molecular mechanisms of hair follicle formation and discusses potential future clinical applications for treating hair loss and skin tumors, but it reports no new clinical results.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This study found that while Eda and Edar proteins interact in vitro, their roles in dental development differ, with downless mutant mice showing distinct tooth defects compared to tabby mutants.

This study found that Msx2-deficient mice exhibit skull and bone formation defects similar to those seen in human MSX2-related conditions, highlighting the gene's importance in skeletal and organ development.
