Controlled differentiation of hematopoietic (blood) cells

Our aim is to understand the regulation of hematopoietic stem cell (HSC) self-renewal (division with no loss in stem cell potential) and commitment. Applications include HSC expansion for transplantation or gene therapy, the selective production of granulocytic and megakaryocytic postprogenitor cells to eliminate the nadirs in neutrophil and platelet counts after bone marrow transplants, and the production of culture-derived platelets for transfusions. To do this we are (1) evaluating the effects of pO2, pH, and other culture parameters on HSC expansion and differentiation; (2) using RNA interference (RNAi) to modulate commitment and differentiation; and (3) using DNA microarrays to evaluate the associated changes in gene expression. This project is a collaboration with Prof. Papoutsakis at the University of Delaware.

Cell membrane-mimetic culture surfaces for stem cell expansion

Hematopoietic stem cell self-renewal occurs throughout life in the body, but is very difficult to achieve in culture. The ability to expand HSC numbers would greatly facilitate applications in cell and gene therapies, as well as in bone marrow transplantation. We are enhancing the prospects for HSC renewal in culture by mimicking the stem cell "niche" in the bone marrow, which includes stem cell association with stromal (accessory) cells. We are mimicking the niche by developing lipid-based and polymer-based surfaces for the presentation of multiple cell adhesion molecule (CAM) ligands and bound growth factors that are normally presented by stromal cells and/or the stromal cell extracellular matrix. This project is a collaboration with Prof. Messersmith in Biomedical Engineering, and combines aspects of materials science (surface preparation and characterization) and stem cell biology (evaluation of HSC responses).

Therapeutic protein and viral vector production

The culture environment affects cell growth and protein production. We have examined inhibition of cell growth by the metabolic by-product CO2, and have evaluated genetic and biochemical approaches to mitigate this inhibition. Also, together with Prof. Aiyar of LSU Health Sciences Center, we have examined parameters (pH, cholesterol supplements, and vector stoichiometry) that affect the production and transduction efficiency of retroviral vectors for gene therapy applications.
