The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a method for inducing human embryonic stem cells to differentiate into dendritic cells.
OVERVIEW
Dendritic cells are used as a base for vaccines and in the study of antigen processing within the human body. However, obtaining large quantities of the cells, which are generated in bone marrow, is labor-intensive and risky for the donor.
THE INVENTION
UW-Madison researchers have developed an in vitro method for inducing human embryonic stem cells to differentiate into dendritic cells. Stem cells are cultured successively in three different environments for between seven and 10 days each. The first environment induces them to become hematopoietic cells, the second directs the hematopoietic cells to become myeloid precursor cells, and the third causes the myeloid precursor cells to develop into immature dendritic cells. The resulting dendritic cells are morphologically, phenotypically and functionally similar to dendritic cells in vivo.
APPLICATIONS
- Production of large amounts of dendritic cells
- Cells can potentially be used in gene therapy to treat cancer or graft rejection.
KEY BENEFITS
- Provides an in vitro method of obtaining large amounts of fully functional dendritic cells and myeloid dendritic cell precursors
- High yielding - greater than 95 percent of cultured stem cells differentiate into dendritic cells
- High production allows multiple vaccinations to be given from one line of cells.
- Low risk of pathogen contamination
- Efficient; only requires exposing stem cells to differentiation-mediating factors, rather than extracting dendritic cells from the blood
STAGE OF DEVELOPMENT
Successfully used to differentiate multiple human embryonic stem cell lines into dendritic cells.
