FAQ
What assays are typically required for iPSC characterization?
A comprehensive iPSC characterization strategy typically includes cell identity verification, pluripotency validation, genomic stability assessment, differentiation potential testing, and quality control evaluation. Common assays include STR profiling, pluripotency marker analysis, karyotyping, differentiation assays, mycoplasma detection, and sterility testing.
How is pluripotency validated in iPSC lines?
Pluripotency is commonly evaluated using a combination of phenotypic, protein, and gene expression analyses. Typical approaches include alkaline phosphatase staining, immunocytochemistry, flow cytometry, qPCR, and RNA sequencing to assess the expression of key pluripotency markers such as OCT4, SOX2, NANOG, TRA-1-60, TRA-1-81, and SSEA-4.
Why is genomic stability assessment important?
Genomic abnormalities may arise during reprogramming, long-term culture, or cell expansion. Assessing genomic stability helps ensure the reliability, reproducibility, and safety of iPSC lines. Cytogenetic analyses such as G-banding karyotyping and M-FISH are commonly used to identify chromosomal abnormalities and structural rearrangements.
What quality control tests should be routinely performed for iPSC cultures?
Routine quality control testing generally includes mycoplasma detection, sterility testing, morphology monitoring, and periodic genomic stability assessment. Regular quality evaluation helps maintain healthy cell cultures and ensures reliable downstream experimental results.
When should iPSC characterization be performed?
iPSC characterization is recommended following initial colony establishment, clone selection, cell banking, long-term culture, and prior to downstream applications such as differentiation studies, disease modeling, drug screening, or cell therapy development. Regular characterization helps ensure consistent cell quality throughout the project lifecycle.
Can you customize characterization packages based on project requirements?
Yes. Characterization strategies can be tailored according to project goals, regulatory expectations, cell type, and development stage. Customized testing packages may include selected assays for identity verification, pluripotency assessment, genomic stability analysis, differentiation evaluation, and quality control testing.
