This study reports that the differential expression patterns of three retinaldehyde dehydrogenases suggest a regulated need for retinoic acid synthesis in various organs during late mouse organogenesis.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This paper reviews the evolution of skin appendages and keratin-associated proteins among amniotes, proposing a model for their genetic divergence without new experimental results.

Secreted inhibitors of Wnt and IGF signaling control hair and tooth development, creating species-specific patterns.

In this study, researchers observed that dorsal horn cells in fetal sheep begin responding to natural cutaneous stimulation by mid-gestation, coinciding with the initial innervation of the skin.

This study found that adhesion molecules, specifically integrins and cadherins, are crucial for the down growth and proliferation of hair follicles in human embryos and fetuses.

This study observed that basal cell carcinoma on the scalp shares more similar characteristics with truncal lesions than facial lesions, despite the scalp's proximity to the face.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This review discusses human hair follicle development and highlights the potential of creating human in vitro models and skin substitutes with hair follicles, reporting no new clinical results.

In this study, engineered skin substitutes containing murine dermal papilla cells developed hair follicle-like structures when grafted onto mice, suggesting a model for generating chimeric hair.

This article discusses scalp reconstruction techniques using rotation flaps, with no new clinical results reported.

This article reviews the critical role of hairline design in hair restoration surgery and emphasizes the need for careful planning to avoid poor outcomes, without presenting new clinical data.

In this study, researchers found that during zebrafish telencephalon regeneration, the lesioned hemisphere showed distinct gene expression changes and activated Wnt/β-catenin signaling early after injury, suggesting this pathway's significant role in recovery.

This study found that misexpression of Hoxc8 in mice led to ectopic mammary development and suggests Hox genes may play crucial roles in the regional specification and initiation of cutaneous accessory organs.

This study found that differentiated cells of the corneal epithelium can be converted to hair and interfollicular epidermis through a multistep process involving dermal developmental signals.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

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

This study found that lanugo hair appears earlier on the posterior wall of the trunk than on the anterior wall in human fetuses, with a nearly two-week difference in development time.

In this study, researchers observed that spiral ganglion neurites created more branched networks near FGF-1-coupled beads compared to control beads, highlighting FGF-1's role in hair cell innervation development.

This study reports that different adhesion molecules play distinct roles in the morphogenesis of feathers and hair, influencing processes such as mesenchymal condensation, epithelial folding, and cell death.
