  CBI-HFF, as the first-in-class human feeder cell of fetal origin, is our benchmark product. The cell line used to produce CBI-HFF has been well established and documented through a series of cGMP banking process in Europe, and also has been used to manufacture clinical research product (Taiwan, Japan, and the US) for wound healing purpose. CBI-HFF will be provided in research- and clinical-grade to meet our customers’ varied needs.

   Research grade CBI-HFF is produced in Class 100,000 clean room environment, whereas the clinical-grade product will be produced in the highest quality in compliance with the GMP principle to support therapeutic product development of our customers. In short, we intend to provide our valued customers a seamless and painless experience in the feeder cell systems switches while they advance their cell therapy products from research into clinical stage.
