Abstrakt: The major objective of this study is to develop a novel and broadly applicable immunotherapy platform against cancer and infectious diseases. We hypothesized that human embryonic stem cells (hESC) could serve as a source for generating dendritic cells (DC) with potent immunostimulatory function. One advantage of using hESC-derived DC in clinical settings is the ability to generate virtually unlimited amounts of antigen presenting cells for vaccination. Although hESC-derived DC are not genetically identical to the recipient patient, antigen processing and presentation can be facilitated by matching hESC to recipients that share HLA class I alleles. Another advantage of this technology is that hESC express highly polymorphic HLA class II molecules that serve as major rejection antigens, thereby augmenting the antigen-specific T-cell response in the cancer patient.
