Induced Pluripotent Stem Cells (iPSCs)
Applied StemCell’s induced pluripotent stem cell (iPSC) catalog includes well-characterized, human iPS cell lines suitable for iPSC culture applications. The high-quality iPSCs are ideal for genome editing, differentiation, and drug toxicity/efficacy screening projects:
- Footprint-free iPSC cells (episomal and other integration-free methods) and retroviral-reprogrammed iPSCs
- Characterized for pluripotency markers, karyotyping, and differentiation potential; more characterization options are available
- Multiple donor tissues: PBMCs, fibroblasts, cord blood, adipocytes from healthy and diseased patients
- Tested for CRISPR genome editing and differentiation potential into various cell lineages
- Ideal as master iPSC cell lines to build engineered and/or panels of differentiated isogenic cell lineages
Along with human iPSCs, we provide mouse embryonic stem cells (mESCs) and mouse iPSCs. Contact us today to learn more about our ready-to-use iPSC control lines.

Non-human Stem Cells & iPSCs
Applied StemCell’s provides a variety of human iPS cells from different donors and tissue sources to fit a wide variety of applications. Our iPSC cell lines are generated primarily using footprint-free, reprogramming methods (episomal and other non-integrating techniques) by transient expression of human transcription factors that initiate the reprogramming process. The singlecell clones of the resulting iPSCs are carefully selected using morphological criteria without the use of fluorescent markers or drug selection. These iPSCs are then characterized extensively for expression of pluripotency markers, karyotyping, directed-differentiation into various cell lineages and the capability for CRISPR/Cas9 genome editing. We also provide optional in-depth characterization options such as whole genome sequencing, RNA-seq, STR analysis (of parental cell and iPSC), high resolution karyotyping using array analysis, EB formation, copy number variation (CNV), and HLA typing, as suited for your requirements.
Some of our control human iPSC cell lines that are ideal as master iPSCs include:
- These iPSCs have proven differentiation capability to NK cells, T cells, neurons, cardiomyocytes, and more
- Suitable for genetic modification using CRISPR/Cas9 and TARGATT™
- They serve as isogenic controls for engineered cell lines
- Multiple donors and tissue sources provide a broad genetic background for basic research, drug and toxicity screening applications

Characterization of iPSC Line, ASE-9211
Figure 1. Expression of pluripotency markers. ASC 9211 iPS cell line expresses common iPSC biomarkers (top row: OCT-4, SOX2, SSEA-4, TRA1-60, and TRA-1-81). Bottom row: Corresponding DAPI nuclear staining. All images were taken at 10x magnification.
Figure 2. Alkaline Phosphatase (AP) staining. ASC-9211 iPSCs stain positive for Alkaline Phosphatase: a typical unstained colony (a) was used to
gauge the extent of the AP staining (b). Both images were taken at 5x magnification.
Figure 3. Karyotype analysis to rule out genetic aberrations. This iPSC line demonstrates a normal male karyotype. Cytogenic analysis was performed on twenty Gbanded metaphase cells from human iPSC line, ASE-9211 at passage 15. Nineteen cells demonstrated an apparently normal male karyotype, and one cell demonstrated a nonclonal chromosome aberration, which is most
likely an artifact of culture.
Figure 4. Direct differentiation of ASE-9211 p18 to three germ layers. Immunofluorescent staining for lineage-specific biomarkers of three germ layers after direct differentiation of control hiPSC line, ASE-9211. The ASE-9211 hiPSC line was differentiated to specific lineages of the germ layers using well-established and optimized protocols. Immunostaining for biomarkers of each lineage was performed to confirm lineage commitment. Cells were also co-stained with nuclear marker, DAPI (blue). Images shown are colocalization of biomarker with DAPI. Endoderm (EN) marker: SOX17 (green); Mesoderm (ME) marker: GATA4 (green); Ectoderm (EC) marker: β-III Tubulin (red).
Direct Differentiation of Control ‘Master” iPSC Line, ASE-9209 into the Three Germ Layers
Figure 5. Immunofluorescent staining for lineage-specific biomarkers of three germ layers after direct differentiation of hiPSCs. Control hiPSC line, ASE-9209 (female, fibroblasts) were differentiated to specific lineages of the germ layers using well-established and optimized protocols. Immunostaining for biomarkers of each lineage was performed to confirm lineage commitment. Ectoderm markers: neuronal lineage markers, PAX6 (green), b-III Tubulin (red); Mesoderm markers: Brachyury (green) and GATA4 (red); Endoderm markers: SOX17 (green) and FOXA2 (red); DAPI (blue) was used to stain for nuclear localization.
