Cellartis DEF-CS 500 Culture System citation list
Takara Bio has over 15 years of experience in expanding, passaging, and culturing human pluripotent stem cells under the Cellartis brand. The DEF-CS 500 system is a complete solution for the easy culturing of human pluripotent stem cells in a noncolony, 2D-monolayer format. Cells grown in this system maintain pluripotency and a normal karyotype while exhibiting robust and uniform growth. Single-cell passaging enables the ability to directly isolate and expand single clones, including cells that have undergone CRISPR/Cas9 gene editing.
Read below for a citation list of studies in which the DEF-CS 500 system was used in peer-reviewed basic, translational, preclinical, and biomedical research.

25 different human pluripotent stem cell lines were maintained with the DEF-CS system, and their pluripotency was confirmed. Karyotyping of the stem cells maintained using the DEF-CS system for up to 29 passages showed no genetic aberrations. These stem cell lines were then successfully differentiated into functional hepatocytes.

Chondrocyte-derived and fibroblast-derived iPSCs were maintained using the DEF-CS system in a monolayer before these cells were successfully differentiated down to the chondrogenic lineage.
