The first commercially available Seq‐Well microfluidic platform was the C1 by Fluidigm. In the membrane, the beads are removed, followed by cell lysis and mRNA capture. In another microfluidic technology, characterized as Seq‐well, cells are incorporated into capture beads that are confined in subnanoliter wells and sealed with a semipermeable membrane. The 10× technology has also developed protocols which conduct immune cell mapping and profiling of specific developing leukocytes by screening the VDJ leukocyte‐specific genes of T‐cell immune receptors (TCR). This protocol has been developed further and commercialized with the use of the Chromium instrument (10× Genomics), which is widely used in dermatological research projects. Each bead has a cellular barcode which is unique to each droplet, as well as unique molecular identifiers (UMIs) representing each RNA molecule. Which encapsulates cells into independent microdroplets with unique barcoded beads. On the contrary, a popular 3’ or 5’ end counting‐based approach is the droplet microfluidics technology known as Drop‐seq, Smart‐seq2, which is the most widely used smart‐seq technology, provides higher sensitivity and efficiency in capturing RNA molecules. Smart‐seq is a full‐length transcription sequencing method based on a switching mechanism, in which nucleotides at the end of the RNA template are added, allowing the reverse transcriptase to synthesize the complementary cDNA strand. These technologies can be broadly classified into two categories: full‐length transcriptome sequencing and 3’ or 5’ end counting‐based sequencing. The aim of this review is to summarize the available technologies and the technical considerations of single‐cell transcriptomics, as well as provide a comprehensive compendium of scRNA‐seq applications in dermatological research.Ĭurrently, available technologies of scRNA‐seq library generation comprise of cell lysis, reverse transcription into first‐strand cDNA, second‐strand synthesis and cDNA amplification. This approach can be very promising in drug development, in which cell‐specific transcriptomic responses to treatment can be analysed. Moreover, scRNA‐seq can be used as a diagnostic tool in precision medicine by deciphering disease‐related biomarkers and pathways.

Importantly, scRNA‐seq allowed researchers to uncover de novo cell populations and lineages that may be implicated in differentiation and development. the development of single‐cell transcriptomics led to the revelation of gene expression variability amongst identical or distinct cell types. Since the first single‐cell RNA‐seq (scRNA‐seq) study conducted by Tang et al. Earlier approaches such as bulk RNA‐seq and microarrays provided information about the average transcriptome status of an entire tissue or sample.

The transcriptomic profile of skin can provide information on gene expression, non‐coding regulatory elements and gene splicing, and therefore shed light on skin physiology and pathology. The human skin is defined by a multilayer architecture based on diverse cell populations of mainly keratinocytes and fibroblasts, as well as various immune cells, melanocytes, adipocytes and endothelial cells that orchestrate events leading to wound repair of pathogenic infections and exposure to ultraviolet radiation and toxic compounds.
