A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with specific expression patterns validated in human skin tissue samples and cell lines using qRT-PCR, microarrays, and next-generation sequencing [Siu et al. DOI:10.1111/wrr.13100]. A study in human ex vivo skin models demonstrated that the miR-367-3p could not be detected by qPCR in the exosome-enriched fractions of dermal interstitial fluid following a burn injury [Foessl et al. DOI:10.3390/ijms22179209].
