Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

This study found that keratins have evolutionarily conserved and domain-selectively enriched amino acids, which likely reflect their unique structural roles, with distinct patterns observed among epidermal, hair, and simple-type epithelial keratins.

This study found that about 80% of known fullerene-binding proteins rank in the top 10% of scorers for C60 docking sites, confirming the accuracy of the predictive model used.

This study found that keratin and other hair proteins in humans are extensively modified posttranslationally, which helps explain the structural characteristics of mature hair.

This review explains the genetic diversity of sheep wool keratin-associated protein genes and explores how this variation might be leveraged for selective breeding to enhance wool fiber traits.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

In this study, local injection of nanosized recombinant human erythropoietin at the injury site improved skin regeneration and re-epithelialization in a mouse model of deep second-degree burns through coexpression of specific receptors.

In this study, subcutaneous injection of bone marrow mesenchymal stem cells in burned rats significantly improved wound healing by reducing inflammation, scar formation, and wound size, and restoring normal skin structures.

This review discusses the role of Ysc84/SH3yl1 proteins in linking actin regulation to membrane morphology changes but reports no new experimental results.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

In this study, BECD-treated wavy hair showed reduced undulation and improved straightening after drying, as BECD enhanced the contraction and rearrangement of molecular chains in non-keratin proteins, unlike untreated hair, which retained its wavy structure.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

This review highlights the limited research on sebocyte lipid droplets and their proteins despite their role in sebocyte differentiation and potential involvement in skin diseases like acne and alopecia, and reports no new results.

This study characterized the Hoxc-13 gene from sheep wool follicles, noting its potential autoregulatory role and potential influence on skin function beyond hair keratin regulation.

This study found that minoxidil increases the expression of a reporter gene linked to hair growth in cultured hair follicles from transgenic mice, suggesting a potential model for studying hair biology.

KAP genes are crucial for hair development and show both shared and unique traits in humans, chimpanzees, and baboons.

This study utilized the DNP–SANS technique on human hair for the first time and found significant changes in the SANS profile dependent on polarization conditions, providing insights into the structural composition and dynamic properties of keratin and its associated proteins.

This study found that encapsulating dermal papilla spheroids in alginate hydrogel with extracellular matrix proteins increased alkaline phosphatase activity, suggesting an enhanced manipulation of dermal papilla activity.

This study highlights the successful design of recombinant fortilin constructs for potential drug development targeting atherosclerotic plaque formation in cardiovascular disease.

This study found that Rap1 deficiency in mice may lead to telomere shortening, DNA damage, and impaired mitochondrial function, contributing to cardiac aging and dysfunction.

This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.

Gene expression in wool follicles changes with growth cycles, offering insights into wool and human hair growth.

In this study, researchers identified a putative ovine KAP24-1 gene in sheep, revealing four unique DNA sequences with some similarity to KRTAP24-1 sequences from other species.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This study found that the orphan protein Plet-1 is expressed in specific keratinocytes of mouse hair follicles and may regulate keratinocyte interactions with inert tissues by affecting migration and adhesion.

In this study, researchers found that the EDMTFH protein is present in specific layers of the chicken embryo skin and feathers, suggesting its role in feather mechanics and development.

This study found that intradermal injection of Secreted Frizzled-related Protein 4 inhibits, but does not block, hair follicle regeneration in mice, suggesting potential therapeutic applications for hair follicle regeneration disorders.
