What are your quality controls measures? What kinds of QC/testing are performed to make sure only quality cells are delivered every time?
We follow the cells from early culturing and throughout observing morphology and growth characteristics. We perform immunophenotype staining throughout the culture at various time points. Cells are then differentiated into the 3 germ layers. Once differentiation is confirmed, they are cloned. Cloned cells are then differentiated into the representative 3 germ layers; phenotyping is performed as well. These tests are performed on early and late passaged cells for confirmation. In addition, gene expression and genetic stability by microarray are performed. Cells are also tested for HIV-1 DNA, HIV-2 DNA, HBV DNA, HCV-RNA, CMV-DNA, mycoplasma DNA and sterility.
