Stem Cell Characterization Service

Reprogramming human induced Pluripotent Stem Cells (hiPSCs) is a fundamental task of stem cell research. In order to provide reliable cell models for drug discovery and preclinical research, an extensive characterization of the generated hiPSC is essential. Our scientific team supports you with a comprehensive stem cell characterization service, investigates your hiPSC lines and provides you with reliability for your research project. We offer state-of-the-art characterization such as the directed trilineage differentiation for the proof of functional pluripotency in addition to the analysis of marker gene expression by RT-qPCR, immunostaining or flow cytometer.

In addition to the hiPSC characterization, trenzyme also offers a customized Stem Cell Differentiation Service and our Cell Line Expansion Service for banking of your hiPSC.

Stem Cell Characterization Service

Characterization of human induced Pluripotent Stem Cells (hiPSC)

The field of human induced pluripotent stem cell (hiPSC) technology is a promising tool for drug discovery, toxicological in-vitro tests and regenerative medicine.

Since the first generation of hiPSCs, numerous reprogramming techniques have been established. However, the in-vitro process of reprogramming is still not fully understood. Often, the cellular stress, induced by the reprogramming process causes genetic and epigenetic alterations that can change the cellular phenotype and affect the integrity of experiments using these cell lines. It is therefore crucial to establish reliable molecular and functional assays to assess pluripotency and to exclude genetic aberrations due to the reprogramming process.

trenzyme’s routinely performed assays to validate your hiPSC lines include the characterization of cells for their expression of pluripotency markers via immunocytochemistry (ICC) and qPCR, molecular karyotyping, as well as the evaluation of their differentiation potential by directed trilineage differentiation.

Stem Cell Characterization FAQs

What general quality control is performed on the iPSC lines?

All iPSC lines are subjected to a standard set of quality control assays, investigating sterility, mycoplasma, viability, and morphology.

What kind of assays will be performed to functionally characterize the iPSC lines?

In order to characterize iPSC lines for the expression of pluripotency markers, immunoflourescence staining and/or flow cytometry for key pluripotency markers OCT4, SOX2, SSEA-4, TRA-1-60, and TRA-1-81 will be performed. Furthermore, the ability to form all three germ layers will be investigated via directed differentiation towards endo-, meso-, and ectoderm (immunoflourescence staining, RT-qPCR).

What kind of karyotyping will be performed?

In order to evaluate genomic stability, chromosomal abnormalities, and copy number variants, molecular karyotyping via Illumina BeadArray will be applied.
