Andrew Potter DOI:10.17504/protocols.io.r8id9ue Human Cell Atlas Method Development Community This protocol is used to dissociate adult (10 week) CD-1 mouse liver "on ice", preserving authentic gene expression profiles. The first layer consists of 3.5 hours rotation at 4 °C in 0.25% trypsin, and the second layer consists of 15 min. in bacillus licheniformis, with trituration on ice. The yield is 5000 cells/mg with 97% viability (as measured by trypan blue).  University of Cincinnati 1 2018 Andrew Potter 2018.

Daniel Gyllborg, Mats Nilsson DOI:10.17504/protocols.io.xy4fpyw Human Cell Atlas Method Development Community, Molecular Diagnostics - Mats Nilsson Group, Neurodegeneration Method Development Community Protocol for multiplexed in situ sequencing in tissue sections as an image-based spatial transcriptomic method. This is the second iteration of In Situ Sequencing (HybISS: Hybridization based In Situ Sequencing) based on the principles published in Ke et al. Nature Methods, 2013 and more recently Qian et al. Nature Methods, 2019. Here we present a modified method in detection chemistry using sequencing by hybridization approach for combinatorial decoding. This results in a more robust method for detecting larger probe panels for a more high-throughput in situ sequencing method.

Daughter of Frankenstein protocol for nuclei isolation from fresh and frozen tissues using OptiPrep® continuous gradient
 
Resource Report
Resource Website
Luciano Martelotto DOI:10.17504/protocols.io.bs99nh96 Human Cell Atlas Method Development Community, Single Cell Core, Harvard Medical School This protocol is the result of the combination of various nuclei isolation protocols for single cell RNA-seq experiments using droplet-based methods, and is an extension of the Frankenstein (D.O.F means Daughter Of Frankenstein). Developed to prepare nuclei isolates from fresh and frozen material of small-to-large sizes. The good thing is that it does not uses FACS but OptiPrep® continuous gradient to remove debris. It is the alternative protocol when FACS is not available. This protocol works better with smaller samples. After centrifugation the nuclei will form a pellet and contaminating membranes will float at the top. This continuous gradient can be applied for as many times as needed to the same prep to continue cleaning up your nuclei suspensions.

Chang DOI:10.17504/protocols.io.q6gdzbw Human Cell Atlas Method Development Community, HYChangLab Here we introduce Protein-indexed Assay of Transposase Accessible Chromatin with sequencing (Pi-ATAC) that combines single-cell chromatin and proteomic profiling. In conjunction with DNA transposition, the levels of multiple cell surface or intracellular protein epitopes are recorded by index flow cytometry and positions in arrayed microwells, and then subject to molecular barcoding for subsequent pooled analysis. PiATAC simultaneously identifies the epigenomic and proteomic heterogeneity in individual cells. Pi-ATAC reveals a casual link between transcription factor abundance and DNA motif access, and deconvolute cell types and states in the tumor microenvironment in vivo. We identify a dominant role for hypoxia, marked by HIF1A protein, in the tumor microvenvironment for shaping the regulome in a subset of epithelial tumor cells.

Consequently, improving its sensitivity, flexibility and cost-efficiency can advance many research questions. Among the flexible plate-based methods, “Single-Cell RNA-Barcoding and Sequencing” (SCRB-seq) is one of the most sensitive and efficient ones. Here, we systematically evaluated experimental conditions of this protocol and find that adding polyethylene glycol considerably increases sensitivity by enhancing cDNA synthesis. Furthermore, using Terra polymerase increases efficiency due to a more even cDNA amplification that requires less sequencing of libraries. We combined these and other improvements to a new scRNA-seq library protocol we call “molecular crowding SCRB-seq” (mcSCRB-seq), which we show to be  the most sensitive and one of the most efficient and flexible scRNA-seq methods to date.

Satija Lab DOI:10.17504/protocols.io.nkgdctw Human Cell Atlas Method Development Community, Satija Lab This protocol presents a simple modification of the SMART-seq2 (Picelle et al, 2014) and SCRB-seq (Soumillon et al, 2014) protocols, with the goal of combining the sensitivity of SMART-Seq2 with the improved cost and throughput of 3' single cell protocols. Reverse transcription (RT) and PCR proceed as in SMART-Seq2, but using 3' barcoded oligos from SCRB-seq. While most barcoded methods (including SCRB-seq) pool cells together after RT, we perform PCR individually in each well, as this negates the need for an additional exonuclease and purification step, and therefore maintains the same molecular sensitivity as SMART-Seq2. However, we pool amplified cDNA from single wells immediately after PCR, and generate a single tagmentation-based 3' cDNA library. While this protocol therefore has advantages in both sensitivity and throughput, the absence of an exonuclease step prior to PCR disables the use of unique molecular identifiers for quantification.
