概要: We provide single cell transcriptomes from the placental-uterine interface. Tissue was collected at term C-section (no labor) from two healthy pregnancies, from villous part of the placenta. Cells were disassociated and processed using Fluidigm technology. RNA-seq was performed on RNA from 33+54 single cells, at approx. 3.5 mio paired reads per cell. Clustering resulted in 4 trophoblast and a single immune cell clusters. As the placenta is an epitome of cell signaling, we combined the present cell-level transcriptomes with uterine cell transcriptomes to study the potential inter-cell communication. To this end, we inferred the cell-cell-interactome by assessing the gene expression of receptor-ligand pairs across cell types. We find among the signals transmitted a predominance of growth and immune signals, and suggest a delicate balance of enhancing and suppressive signals. Finally, this study provides a rich resource of gene expression profiles of term intravillous and extravillous trophoblasts.

处理方案: Tissue underwent serial trypsin and collagenase digests and the resulting cell suspension was layered on a continuous Percoll gradient. Cells were collected from the 20-60% fractions. Collected cells were filtered through a 40um cell filter and underwent Trypan blue exclusion to assess viability. Cell suspension at 3x10^5 cell/ml was submitted to Cincinnati Children's gene expression core for single cell capture using Fluidigm integrated fluidic circuit.
提取方案: C1 Single-Cell Auto Prep Integrated Fluidic Chip for mRNA-seq (17-25 micron cell size selection).
建库方案: Nextera XT DNA Library Preparation Kit - manufacturer's recommendation.
