Single-cell ID-seq identifies BMP signaling as a driver of a late stage epidermal differentiation program

ABSTRACT: We developed a single cell application of the sequencing-based immunodetection method ID-seq which makes it possible to multiplex measurements of many different epitopes from proteins and phosphoproteins in a high throughput setting. A FACS sort step was implemented to allow sorting of single cells in 96 well plates. With these DNA-tagged antibodies and dedicated sample preparation protocol adapted for single cells, we studied the studied the changes of 70 (phospho-)proteins in primary human skin cells compared to a subpopulation with low ITGB1 protein expression. Given that ITGB1 is a skin stem cell marker, we indeed found that the ITGB1 low cells are differentiated and we found a role for BMP signaling in this process.

Immuno-Detection by sequencing (ID-seq) enables large-scale high- dimensional phenotyping in cells

Project description:We developed a sequencing-based immunodetection method which makes it possible to multiplex measurements of many different epitopes from proteins and phosphoproteins in a high throughput setting. With these DNA-tagged antibodies and dedicated sample preparation protocol, we studied the effect of hundreds of kinase inhibitors on 70 (phospho-)proteins in primary human skin cells.

Gene expression profiling of mouse embryonic stem cells with single-cell RNA sequencing

Project description:Differences in gene-expression profiles between individual cells can give rise to distinct cell fate decisions. Yet how localisation on a micropattern impacts initial changes in mRNA, protein, and phosphoprotein abundance remains unclear. To identify the effect of cellular position on gene expression, we developed a scalable antibody and mRNA targeting sequential fluorescence in situ hybridization (ARTseq-FISH) method capable of simultaneously profiling mRNAs, proteins, and phosphoproteins in single cells. We studied 67 (phospho-)protein and mRNA targets in individual mouse embryonic stem cells (mESCs) cultured on circular micropatterns. To validate the detection of the mRNA targets quantified with ARTseq-FISH, we utilized single-cell RNA sequencing to profile a comparable population of mouse embryonic stem cells.

scRNASeq data of CD45+CD3-CD19- and keratinocytes in normal and HS skin

Project description:Hidradenitis suppurativa (HS) is a highly prevalent, morbid inflammatory skin disease with limited treatment options. The major cell types and inflammatory pathways in skin of HS patients are poorly understood. We profiled via scRNASeq myeloid cells and keratinocytes sort-purified from two healthy skin samples and two samples with HS pathology to determine major cell types and transcriptional pathways altered in HS.

A global transcriptome analysis of human dermal fibroblasts upon knockdown or overexpression of the circular RNAs circGLIS3 (circBase ID: hsa_circ_0002874)

Project description:In an RNAseq analysis, we have identified circGLIS3 with high levels acute wound dermis compared to skin. The biological function of circGLIS3 in human dermal fibroblasts during wound repair has not been studied. To study the genes regulated by circGLIS3, we transfected siRNA or plasmid into human dermal fibroblasts to knockdown or overexpress circGLIS3. We performed a global transcriptome analysis of fibroblasts upon circRNA knockdown or overexpression using Affymetrix arrays.

Deciphering the Links: Fragmented Polystyrene as a Driver of Skin Inflammation

Project description:Recent studies have identified the pervasive presence of nano- and microplastics (NMP) in atmospheric air, leading to inevitable human exposure. Human skin, with an extensive surface area of 1.5-2 m², is constantly exposed to airborne NMP, yet the dermal implications of such exposure remain elusive. Our investigation employed fragmented polystyrene (fPS), a plastic commonly found in the air, to evaluate dermal penetration using various skin models. We utilized pyrolysis-gas chromatography/mass spectrometry (py-GC/MS) to quantify fPS that had penetrated the skin model. Furthermore, we examined the biological alterations in skin keratinocytes consequent to fPS exposure and analyzed the regulation of inflammatory response markers. Our findings reveal deleterious effects on skin keratinocytes, underlining the potential risks posed by short-term fPS exposure. This multifaceted skin model study offers new perspectives on the toxicological impacts of NMP.

An epigenetic gene signature underlies phenotype switching in early stage melanomas [Nanostring_sample3]

Project description:A 122-epigenetic gene signature distinguished low- versus high-risk early stage melanomas. We sought to validate the signature, examined clinical correlates in a cohort of primary melanomas of the skin, and studied the underlying transcriptomic aberrations and changes in chromatin in cell lines representing these two groups.
