Mesothelium

Mesothelium is a thin, protective layer of cells that lines the internal body cavities, including the chest (pleura), abdomen (peritoneum), and heart (pericardium).
This specialized epithelial tissue plays a crucial role in reducing friction and facilitating the smooth movement of organs within these cavities.
Mesothelial cells also secrete lubricating fluids that further enhance the efficiency of these internal processes.
Understanding the structure, function, and pathologies of the mesothelium is essential for research into a variety of conditions, such as mesothelioma, a rare and aggresive form of cancer that originates in the mesothelial cells.

Mesothelial cells were isolated from 4 to 6 months old WT and Nf2+/− mice, all on a C57Bl/6J background using a previously described protocol (Bot et al.2003 (link)). Briefly, mice were killed and the peritoneal cavities were exposed by incision and removal of the fur. The peritoneal cavities were washed with injecting approximately 50 ml of phosphate-buffered saline (PBS) (Sigma, St. Louis) via a syringe equipped with a 25G × 5/8″ needle (BD microlance 3, Becton Dickinson AG, Allschwil, Switzerland) using a peristaltic pump and a second needle (23G, 0.6 × 25 mm) to allow exit of the PBS solution. Perfusion was maintained until the exiting PBS solution was clear, i.e., devoid of mobile and poorly attached cells. Residual PBS was aspired with a syringe, and the peritoneal cavity was filled with 5 ml of 0.25% Trypsin/EDTA solution (Gibco, Basel, Switzerland). The body temperature of mouse corpses was maintained at around 37°C for 5 min via an infrared heating lamp. The suspension containing the detached cells was collected with a syringe; cells were centrifuged for 10 min at 300×g. Cells mostly comprising primary mesothelial cells were grown in modified Connell’s medium composed of Dulbecco’s modified Eagle’s medium (DMEM)/F12 + GlutaMax (Gibco), 15% fetal calf serum (FCS), 0.4 μg/ml hydrocortisone, 10 ng/ml epidermal growth factor, 1% ITS (insulin, transferrin, selenium), 1 mM sodium pyruvate, 0.1 mM beta-mercaptoethanol, 1% non-essential amino acids, 1% penicillin–streptomycin, and 2% Mycokill (PAA) (Connell and Rheinwald 1983 (link)). The Nf2 alleles (WT or mutated) were genotyped using the common forward primer (NF2_FW 5′-GGGGCTTCGGGAAACCTG G-3′), and either NF2_RV WT (5′-GTCTGGGAAGTCTGTGGAGG-3) or NF2_RV mutant (5′-CTATCAGGACATAGCGTTGG-3′) primers. The cell line RN5 was isolated from an Nf2+/− mouse that was repeatedly injected with crocidolite starting at 8 wk of age (7 × 400 μg). Briefly, a clearly discernible tumor localized on the liver was dissected from the mouse 21 wk after the first injection. The tissue was incubated in a 0.25% Trypsin/EDTA solution for 10 min; tumor cells were dissociated by mild trituration and cultured in DMEM, 10% fetal bovine serum (FBS, Gibco, Basel, Switzerland), and 1% PS (100 U/mL penicillin and 100 μg/mL streptomycin).

Integration, clustering and subclustering analysis were performed using Seurat 3.9.965 . The gene counts were normalized using SCTransform66 , and regressed on mitochondrial read percentage, ribosomal read percentage, and cell cycle score as determined by Seurat. In order to avoid smoothing over depot differences, for integration human and mouse data were grouped by ‘individual’, i.e., if both subcutaneous and visceral adipose tissue for an individual human or mouse were available, they were pooled together during this step. Individuals were integrated with reciprocal PCA, using individuals that had both subcutaneous and visceral samples as references. As a result, the human and mouse references were comprised exclusively from the sNuc seq cohort. To integrate, references were integrated together, then the remaining samples—sNuc seq individuals with only subcutaneous data as well as all Drop-seq samples—were mapped to the reference. For clustering, 5000 variable genes were used, and ribosomal and mitochondrial genes were removed from the variable gene set before running PCA and calculating clusters using a Louvain algorithm, 40 PCs, and a resolution of 0.5. Clusters were identified as adipocytes, preadipocytes, mesothelial cells, vascular cells, or immune cells using marker genes, subset into individual objects, and re-integrated using the above method. Samples with fewer than 50 cells in the subset were removed before re-integration. This led to samples having artificially fewer cells in some instances—for example some Drop-seq samples had cells that clustered with adipocytes, but these cells were removed in subclustering because the small numbers of cells introduced too much variability into the integration. Subclustering was performed using a range of variable genes (1000-2000), PCs (10-40) and resolutions (0.2-0.6). Markers were calculated using a non-parametric Wilcoxon rank sum test with p values adjusted using Bonferroni correction (Supplementary Tables 1, 2), and clusters were evaluated based on the distinctness of called markers to determine the final subclustering conditions. In the subclustered objects, we removed clusters that appeared to represent doublets based on the score assigned by scrublet61 , or that appeared to be driven by high ambient RNA content as determined by percentage of mitochondrial genes and spliced/unspliced RNA ratio. The remaining clusters were annotated based on marker gene expression. In some cases, smaller subclusters (T and NK cells, B cells, monocytes/neutrophils) were further subset and PCA and clustering analysis but not integration was re-run in order to assign clusters. After subcluster annotation, identities were mapped back onto the original object and cells that were removed from the subclustered objects were similarly removed from the all-cell object.

Following CHB, each animal was carefully removed from the chamber and positioned in dorsal recumbency for necropsy examination. The skin was incised along the midline and the injection site was identified in the abdominal wall musculature. The abdominal wall was incised and the intestines were reflected out of the abdominal cavity. Distribution of blue injectate and any misinjection into hollow viscera were noted. The liver was reflected cranially and any presence of dye within the biliary vessels caused by uptake of injectate from the peritoneal cavity and subsequent biliary excretion was noted. The GIT from the cardia to the descending colon was removed and any intestinal segments with dye-stained serosa were opened to confirm or rule out intraluminal misinjection. Misinjection was defined as the presence of blue injectate within hollow viscera or subcutaneous tissues, or staining the fur. For each rat, the serosal surfaces of the abdominal wall injection site, the caudate liver lobe, and transverse sections of at least three intestinal sections were examined histologically after formalin fixation for evidence of acute inflammation or swelling of mesothelial cells. Evaluation was performed by a single board-certified veterinary pathologist (CK), who was blinded to treatment group assignments.

The data set consists of expression data for single cells obtained from 9 patients (4 with matching primary and metastatic samples) in three locations and thus cellular categories: a primary tumor site (ovary or fallopian tube) with 1,649 cells, metastatic site (omentum) with 1,062 cells, and normal site (ovary) with 355 cells. The normal cells are comprised of fibroblasts, stromal cells, and mesothelial cells. When we perform PCA on all the cells, the normal cells do not cluster by cell type and the primary cells do not cluster by location.

All experiments used ovarian cancer tumor cell lines OV-90, OVCAR-3, and OVCAR-8 (ATCC). Cell lines were authenticated by human short tandem repeat (STR) analysis at the TRIP Lab at the University of Wisconsin–Madison. Cells were cultured in 1:1 Medium 199 (with Earle's salts and L-glutamine, Sigma-Aldrich) and MCDB 105 medium (Sigma-Aldrich). Experiments were conducted in serum-free medium, and maintenance culture included 15% heat-inactivated fetal bovine serum (FBS). LP-9 mesothelial cells (Coriell) were cultured in 1:1 Medium 199 and Ham's F-12 supplemented with 200 ng/mL hydrocortisone, 5 ng/mL epidermal growth factor, 0.75 mM L-glutamine, and 10% FBS. All media included 1% penicillin–streptomycin.

Fresh peritoneal tissue was obtained directly from the operating room, with informed consent from the patients, and transferred immediately to the laboratory in E199 medium (Biochrom AG, Berlin, Germany). The tissue samples were then incubated for 15 min in phosphate-buffered saline (PBS) containing penicillin/streptomycin and amphotericin B (Sigma-Aldrich Chemie, St. Louis, MO, USA). Extraperitoneal fat was removed, and 7 × 7 mm tissue pieces were inserted between two stainless steel rings, which are available in various sizes, and thus enable large variations in the setting of these experiments. Moreover, stainless steel rings are more stable than plastic rings. In this setup, the ring system allows for tissue orientation with the mesothelial cells pointing upwards, thereby better reflecting the peritoneal cavity in the in vivo setting. The peritoneum was cultured in E199 medium containing penicillin/streptomycin, L-glutamine (Biochrom AG), FCS (Thermo Fisher Scientific), hydrocortisone (Sigma-Aldrich Chemie), fibroblast growth factor (PeproTech GmbH, Hamburg, Germany), and heparin (Biochrom AG), as described previously [12 (link)].

A total of 100 × 106 Met5a cells (a human mesothelial cell line, ATCC CRL-9444) were grown in M199 medium supplemented with 10% heat-inactivated fetal bovine serum (FBS), L-glutamine 2 mM, 100 U mL−1 penicillin and 100 U mL−1 streptomycin, 3.3 nM epidermal growth factor (EGF), 400 nM hydrocortisone, 870 nM insulin at 37 °C in a 5% CO2 atmosphere in 250 ml flasks. Confluent MeT5A cultures were detached with trypsin, washed, counted in a Beckman Coulter Counter Z1, and stored at −20 °C until re-suspended in 25 mL of Tris-HCl buffer 20 mM pH 7.0 containing proteinase inhibitors (cOmplete Protease Inhibitor Cocktail, one tablet dissolved in 50 ml extract). The cells were disrupted in an N2-cavitator at 350 psi for 20 min at 4 °C and the lysate centrifuged at 1000× g for 20 min at 4 °C. The post-nuclear (PNS) fraction was carefully withdrawn and centrifuged in a himac CS150NX (Hitachi) micro ultracentrifuge for 60 min at 4 °C at 100,000× g. The pellet (p100 MET), a membrane rich fraction, and the cytosol (s100) were carefully separated. P100 MET was extracted in 10 mL of 20 mM Tris-HCl pH 7.0 containing 1.5% β−octyl-glucopiranoside (OG) and 1 M NaCl, overnight at 4 °C. The extract was centrifuged at 1000× g to avoid precipitates and extensively dialyzed against 20 mM Tris-HCl pH 7.0. The dialysate was re-centrifuged at 20,000× g in the Hitachi centrifuge to eliminate few small precipitates of unknown origin and filtered through a 0.2 μm pore size membrane (Minisart filter, Millipore, Sigma-Aldrich, Merck, Darmstadt, Germany).
