This phase I trial studies side effects and best dose of T-allo10 cells and to see how well they work when given before donor stem cell transplant in treating patients with blood cancer that has come back or does not respond to treatment. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft versus host disease). Giving T-allo10 cells before the transplant may help prevent this from happening. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient’s immune cells and help destroy any remaining cancer cells. Giving T-allo10 cells before donor stem cell transplant may work better in treating patients with blood cancer that has come back or dose not respond to treatment.

PRIMARY OBJECTIVES:
I. To assess the tolerability and safety of escalating doses of T-allo10 cell infusions that can be feasibly manufactured to meet release specifications in mismatched related or mismatched unrelated unmanipulated hematopoietic stem cell transplantation (HSCT) in patients with hematologic malignancies.
SECONDARY OBJECTIVES:
I. To assess the incidence of grade III and IV acute graft versus host disease (GvHD).
EXPLORATORY OBJECTIVES:
I. To assess the incidence and severity of chronic GvHD.
II. To assess the time to immune reconstitution.
III. To assess disease free survival.
OUTLINE: This is a dose-escalation study of T-allo10 cells.
Patients undergo fractionated total body irradiation (FTBI) on days -8 to -5. Patients receive cyclophosphamide intravenously (IV) on days -4 and -3. Patients receive T-allo10 cells IV within 30 minutes of thawing of cells on day -1 and undergo HSCT on day 0.
After completion of study treatment, patients are followed up on days 21, 28, 35, 42, 49, 56 and monthly until day 365.
