Stem Cell Characterization Service

Reprogramming of human induced Pluripotent Stem Cells (hiPSCs) is a fundamental task of stem cell research. In order to provide reliable model cells for drug discovery and preclinical research, an extensive characterization of the generated hiPSC is absolutely essential. Our scientific team supports you with a comprehensive stem cell characterization service investigating your hiPSC lines and providing you with reliability and safety for your research project.

In addition to the hiPSC characterization, trenzyme also provides a customited Stem Cell Differentiation Service.

Characterization of human induced Pluripotent Stem Cells

The field of human induced pluripotent stem cell (hiPSC) technology is a promising tool for drug discovery 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.

“trenzyme is one of our preferred service providers for cell line development and molecular biology services. The impressive level of personal customer liaison and the scientific competence are decisive factors for us to cooperate with trenzyme for many years and even to intensify in the area of demanding iPS cell line projects.”

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.
