Corrigendum to “Endocrine Controls of Primary Adult Human Stem Cell Biology: Thyroid Hormones Stimulate Keratin 15 Expression, Apoptosis, and Differentiation in Human Hair Follicle Epithelial Stem Cells In Situ and In Vitro”

This study observed that keratin-based microspheres promoted hair regrowth in C57BL/6 male mice and enhanced hair growth markers in human dermal papilla cells, suggesting these particles may effectively target hair follicles to aid in hair growth.

This review discusses hair keratins and hair follicle-specific epithelial keratins and their association with inherited hair disorders, reporting no new clinical results.

More research is needed to understand how hair keratins work and their role in hair disorders.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

In this study, in vitro growth of human hair follicles did not alter hair keratin expression patterns, maintaining follicle integrity and proper keratinization similar to in vivo conditions.

Human nails contain both skin and hair keratins, each needing different extraction methods.
