OptiDIFF iPSC Platform

DefiniGEN’s proprietary core technology is a world-leading production platform designed to generate mature, primary-like human endoderm cell types from iPSC.  Our scalable process supports preclinical research through the provision of mature human cells including hepatocytes, pancreatic beta cells and intestinal cells.

The platform uses GMP-compatible defined conditions which enable the exquisite quantitative and temporal process control required to produce standardized populations of terminally differentiated cell products.
