Blood Cells

Blood cells, also known as hematopoietic cells, are the cellular components of blood that play vital roles in the body's physiological processes.
These cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Red blood cells are responsible for transporting oxygen and carbon dioxide throughout the body, while white blood cells defend against infection and disease.
Platelets are essential for blood clotting and wound healing.
Researchers in the field of blood cell research utilize advanced techniques and technologies to study the structure, function, and development of these critical cellular components.
Accurate and reproducible protocols are crucial for advancing our understanding of blood cell biology and improving clinical applications.

FASTQ files of RNA-seq reads were pre-processed with Trimmomatic [22 (link)] to remove adapter sequences and read ends with Phred quality scores lower than 20, to discard reads shorter than 36 bp, and to trim long reads to a maximum length of 50 bp. This analysis is implemented in the “Preprocessing” module of quanTIseq (step 1 in Fig. 1c), which also allows selecting different parameters for data preprocessing.

quanTIseq method and validation based on blood-cell mixtures. a quanTIseq characterizes the immune contexture of human tumors from expression and imaging data. Cell fractions are estimated from expression data and then scaled to cell densities (cells/mm2) using total cell densities extracted from imaging data. b Heatmap of quanTIseq signature matrix, with z scores computed from log2(TPM+1) expression values of the signature genes. c The quanTIseq pipeline consists of three modules that perform (1) pre-processing of paired- or single-end RNA-seq reads in FASTQ format; (2) quantification of gene expression as transcripts-per-millions (TPM) and gene counts; and (3) deconvolution of cell fractions and scaling to cell densities considering total cells per mm2 derived from imaging data. The analysis can be initiated at any step. Optional files are shown in grey. Validation of quanTIseq with RNA-seq data from blood-derived immune cell mixtures generated in [46 (link)] (d) and in this study (e). Deconvolution performance was assessed with Pearson’s correlation (r) and root-mean-square error (RMSE) using flow cytometry estimates as ground truth.

This protocol has been optimized for blood cells. We note that digitonin is a gentle detergent and this protocol may not be ideal for cell lines and other cell types that are more resistant to lysis. 5,000 sorted cells in FACS Buffer were pelleted by centrifugation at 500 RCF for 5 minutes at 4C in a pre-cooled fixed-angle centrifuge. All supernatant was removed using two pipetting steps being careful to not disturb the not visible cell pellet. 50 ul transposase mixture (25 ul of 2x TD buffer, 2.5 ul of TDE1, 0.5 ul of 1% digitonin, 22 ul of nuclease-free water) (Cat# FC-121-1030, Illumina; Cat# G9441, Promega) was added to the cells and the pellet was disrupted by pipetting. Transposition reactions were incubated at 37°C for 30 minutes in an Eppendorf ThermoMixer with agitation at 300 RPM. Transposed DNA was purified using a QIAgen MinElute Reaction Cleanup kit (Cat# 28204) and purified DNA was eluted in 10 ul elution buffer (10 mM Tris-HCl, pH 8). Transposed fragments were amplified and purified as described previously48 (link) with modified primers23 (link). Libraries were quantified using qPCR prior to sequencing. All Fast-ATAC libraries were sequenced using paired-end, dual-index sequencing on a NextSeq with 76×8×8×76 cycle reads.

Human primary fibroblasts were derived from biopsied skin tissue samples. The fibroblasts were established and expanded with DMEM containing 10% autologous human serum. Using these fibroblasts, iPS cells were generated as described previously17 (link). Briefly, following electroporation of reprogramming factors with episomal vectors using the Neon system (Life Technologies), the cells were plated on a non-coated cell culture plate. iPS cells were induced by changing the medium to StemFit™. Twenty to thirty days after plating, iPS cell colonies were observed.
Blood cell-derived iPS cells were generated as described previously16 (link). Briefly, mononuclear cells were prepared from peripheral blood using the Ficoll-Paque PREMIUM (GE Healthcare) separation method. The cells were electroporated with episomal vectors using a Nucleofector 4D system (with P3 Primary Cell Kit, Lonza) and plated on rLN511E8-coated cell culture plates. The iPSCs were induced by changing the medium to StemFit™. Twenty to thirty days after plating, iPS cell colonies were observed. A similar method was used to generate Ff-hiPSCs from human cord blood (provided by the RIKEN Bioresource Center Cell Bank). We generated several clones of Ff-hiPSCs from each experiment.
The experimental protocols dealing with human subjects were approved by the institutional review board at our institute (Kyoto University Graduate School and Faculty of Medicine, Ethics Committee). Written informed consent was provided by each donor.

For each of our examples, we ran a subset of the following six collapsing methods and studied how often each method leads to the most reproducible results. First, we choose the row with the highest mean expression (1.max) by setting method = "MaxMean" and connectivityBasedCollapsing = FALSE. Second, we choose the row with the highest between-column variability (2.var) by setting method = "maxRowVariance" and connectivityBasedCollapsing = FALSE. Third, we choose the row with the highest connectivity in cases with three or more rows per group or highest mean expression in cases with two rows per group (3.kMax) by setting method = "MaxMean" and connectivityBasedCollapsing = TRUE. Fourth, we choose the row with the highest connectivity in cases with three or more rows per group or maximum variability in cases with two rows per group (4.kVar) by setting method = "maxRowVariance" and connectivityBasedCollapsing = TRUE. Fifth, as a sort of control, we compare our results to a standard method of centroid determination by measuring the module eigengene (first principal component) for all rows in a given group across all groups (5.ME) by setting method = "ME". Finally, in our assessment of blood cell type, we also use the average of all marker genes (6.Avg) by setting method = "average".

Example 4

As a non-limiting example, the perfusion chamber or the multi-well plate described herein can be used for drug screening. As shown in FIG. 19, skin or blood cells from human patients having a specific disease can be collected to generate patient-specific induced pluripotent stem cells (iPS cells). The iPS cells can be cultured in a dish to mimic disease-affected cells. Alternatively, the iPS cells can be stimulated to differentiate into an organoid sample, which can be used as a disease model. The organoid sample can be dissected and transferred into the perfusion chamber or the multi-well plate as described herein. Afterwards, the test compounds (e.g., drugs) can be diluted and used to treat the organoid sample in each chamber (or well) with proper controls. Cellular activities and/or intracellular gene expressions can be detected (e.g., recorded) in response to test compounds (e.g., drugs) treatment. The organoid sample can then be subjected to a spatial analysis workflow as described herein. Based on changes of the detected cellular activities and/or the intracellular gene expressions, together with the spatial analysis results, disease-specific drugs can be determined and used to treat the specific disease in the human patients.

Optimization of Morphogen Exposure

The optimal duration of caudalization and ventralization may vary depending on the parent cell line used, culture conditions, and quality of reagents. For cells with ESC origin both caudalization and ventralization are typically 1 day faster, for hiPSC derived from adult cells, the time can depend on the origin of the somatic cells. Several different types of cells have been used to produce iPSCs, including fibroblasts, neural progenitor cells, keratinocytes, melanocytes, CD34+ cells, hepatocytes, cord blood cells and adipose stem cells. In hiPSC derived from CD34+ cells caudalization and ventralization may be slower for up to 2 days. hiPSC derived from fibroblasts typically follow the time line as explained in the FIG. 1.

Example 26

Blood cells, such as mature peripheral blood T lymphocytes, monocytes, macrophages, T cell progenitors, macrophage-monocyte progenitor cells, and/or pluripotent hematopoietic stem cells (such as those found in umbilical cord blood and occupying bone marrow spaces) as well as other stem/progenitor cells can be transfected using the therapeutic vector(s) in vitro. Appropriate concentrations of the therapeutic vector(s) may be those consistent with Browning et al., 1999. Subsequently, cells are expanded (propagated) in vitro, and are then transferred to the host via introduction of the cells to the venous or arterial circulation using an intravenous needle or catheter. Subsequently, cells transfected with the therapeutic vectors are able to “home” to the bone marrow and other tissues.

It is understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this application and scope of the appended claims.
