iPSCdirect™ 単層培養の流れ


Figure 1. Schematic for a Generalized Monolayer Protocol to Thaw and Culture iPSCdirect™ for iPSC-Based Monolayer Workflows
iPSCdirect™ cells can be thawed and plated into mTeSR™ Plus (Catalog #100-0276) supplemented with CloneR™2 (Catalog #100-0691) and incubated overnight according to product instructions. Recommendations for seeding densities to reach the desired confluency at 24 hours may be found in the Product Information Sheet. After 24 hours, cells are ready for STEMdiff™ or customized monolayer workflows. iPSC = induced pluripotent stem cell.




Figure 2. iPSCdirect™ SCTi003-A Cells Can Be Seeded to Reach a Range of Confluencies After 24 Hours
To reach the desired confluency for downstream experiments, thaw and plate iPSCdirect™ cells into mTeSR™ Plus with CloneR™2 (Catalog #100-0276 and #100-0691) at the densities recommended in the Product Information Sheet. These representative examples of (A) low confluency, (B) medium confluency, and (C) high confluency were cultured after thaw on Corning® Matrigel® hESC-Qualified Matrix and imaged at a magnification of 4X.

Figure 3. iPSC Line SCTi003-A, the Source for iPSCdirect™ SCTi003-A, Is Derived from a Healthy Female Donor
Demographic, health, and genetic characteristics of the SCTi003-A donor are compiled based on self-reported information and whole-exome sequencing. Sex was determined by karyotype. Ancestry was calculated by EthSEQ analysis from whole-exome sequencing data. HLA haplotype was determined by next-generation sequencing, sequence-base typing, and sequence-specific oligonucleotide probes as needed to obtain the required resolution. Other genetic variants were determined from whole-exome sequencing using ClinVar analysis. Blood type (ABO/Rh blood group) was determined by next-generation sequencing. Height, weight, and BMI were calculated at the donation facility.



Figure 4. iPSCdirect™ SCTi003-A Human Pluripotent Stem Cells Maintain a Typical Karyotype
G-T-L banding for thawed iPSCdirect™ cells (SCTi003-A p34, n = 40) shows a typical karyotype with no evidence of clonal abnormalities at a band resolution of 425 - 475 G-bands per haploid genome.

Figure 5. Single Nucleotide Polymorphism Microarray Analysis Characterizes iPSCdirect™ SCTi003-A Copy Number Variants Consistent with the Source Cell Line
DNA was extracted from a vial of iPSCdirect™ SCTi003-A iPSCs and subjected to SNP microarray analysis to identify large-scale copy number variants (CNVs). Consistent with the variants detected in the source SCTi003-A cell line (see SCTi003-A product data), the thawed cells display two reportable CNVs, defined as those greater than 400kb in size, on chromosome 7 and 14 (rows highlighted in bold font). These losses are located in the TCR regions of the genome and are indicative of VDJ recombination process during T Cell development. Array design, genomics position, genes, and chromosome banding are based on genome build GRCh37/hg19. chr = chromosome; start cyto = cytogenetic band at the start of the base pair imbalance; end cyto = cytogenetic band at the end of the base pair imbalance; bp = base pairs; SNP = single nucleotide polymorphism; TCR = T Cell Receptor; VDJ = variable, diversity, joining segment.



Figure 6. iPSCdirect™ SCTi003-A Cells Express Undifferentiated Cell Markers
iPSCdirect™ SCTi003-A was characterized using flow cytometry for undifferentiated cell markers OCT3/4 and TRA-1-60. Percentage marker expression was quantified 4 days after thawing, from analyses of three biological replicates (n = 3 vials). Error bars represent the standard deviation.



Figure 7. iPSCdirect™ SCTi003-A Human Pluripotent Stem Cells Demonstrate a High Trilineage Differentiation Capacity
iPSCdirect™ SCTi003-A cells were split into 3 groups, differentiated using STEMdiff™ Trilineage Differentiation Kit (Catalog #05230), and then subjected to flow cytometry analysis. Two markers for each embryonic germ layer were assessed, and bars represent mean marker expression for each group of cells (dots represent the average of 3 technical replicates; error bars represent standard deviation; n = 3 biological replicates). All lineage-specific markers were expressed by more than 70% of differentiated cells. Expression of PAX6 and Nestin confirm differentiation to the ectoderm lineage, NCAM and Brachyury (T) expression confirm differentiation to the mesoderm lineage, and CXCR4 and SOX17 expression confirm differentiation to the endoderm lineage.
