TNC and keloid: In our previous paper “Single-Cell Sequencing Analysis and Weighted Co-Expression Network Analysis Based on Public Databases Identified That TNC Is a Novel Biomarker for Keloid” which was published on 22 December 2021 in Frontiers in Immunology, the genomics of keloid was explored to a certain extent and tenascin-c(TNC) was identified as a robust marker of keloid by single-cell sequencing analysis and WGCNA (9).
