Safety and Efficacy Study of Ex Vivo Immunotherapy for Treatment of Aplastic Anemia

Summary

Our hypothesis is that ex vivo activated immune cells would produce multiple known and unknown potent hematopoietic cytokines, working in concert, these cytokines help stem cell growth and differentiation. Additionally, these cells travel and home to bone marrow as well as spleen and liver involved in hematopoietic activities, where direct cell-cell contact may be beneficial.
