OBJECTIVE: To review recent advances in the application of hair transplantation in wound healing and scar repair in special areas. METHODS: An extensive review of the literature on the application of hair transplantation in wound healing and scar repair in special areas was conducted, focusing on cellular functions, molecular mechanisms, and clinical applications. RESULTS: Hair transplantation has been shown to effectively promote wound healing and scar repair in special areas. The underlying mechanisms are complex, but current understanding emphasizes a strong association with hair follicle-associated stem cells (including epidermal stem cells, dermal papilla cells, dermal sheath cells, etc). CONCLUSION The application of hair transplantation in wound healing and scar repair in special areas remains in its early stages. Further investigation into its mechanisms of action is essential, and randomized controlled trials are needed to establish its efficacy.

As the most pervasive epigenetic marker present on mRNAs and long non-coding RNAs (lncRNAs), N⁶-methyladenosine (m⁶A) RNA methylation has been shown to participate in essential biological processes. Recent studies have revealed the distinct patterns of m⁶A methylome across human tissues, and a major challenge remains in elucidating the tissue-specific presence and circuitry of m⁶A methylation. We present here a comprehensive online platform, m6A-TSHub, for unveiling the context-specific m⁶A methylation and genetic mutations that potentially regulate m⁶A epigenetic mark. m6A-TSHub consists of four core components, including (1) m6A-TSDB, a comprehensive database of 184,554 functionally annotated m⁶A sites derived from 23 human tissues and 499,369 m⁶A sites from 25 tumor conditions, respectively; (2) m6A-TSFinder, a web server for high-accuracy prediction of m⁶A methylation sites within a specific tissue from RNA sequences, which was constructed using multi-instance deep neural networks with gated attention; (3) m6A-TSVar, a web server for assessing the impact of genetic variants on tissue-specific m⁶A RNA modifications; and (4) m6A-CAVar, a database of 587,983 The Cancer Genome Atlas (TCGA) cancer mutations (derived from 27 cancer types) that were predicted to affect m⁶A modifications in the primary tissue of cancers. The database should make a useful resource for studying the m⁶A methylome and the genetic factors of epitranscriptome disturbance in a specific tissue (or cancer type). m6A-TSHub is accessible at www.xjtlu.edu.cn/biologicalsciences/m6ats.
