Trans-differentiation of stem cells shows promise for use in tissue repair medicine. Although poorly defined, mesenchymal stem cells (MSC) appear useful for applications in repair medicine. Despite the low frequency of MSC, they are relatively easy to expand. The expression of MHC class II on MSC, however, could deter their use in repair medicine, since(More)
1,25-dihydroxyvitamin D3 (1,25D) has been shown to influence differentiation, cell proliferation and cell death in cultured leukemia cells. However, its clinical use is limited by its hypercalcemic effects. An analog of 1,25D, doxercalciferol (1-D2), has anti-tumor activity, with markedly reduced calcemic effects, which makes it a potential agent for(More)
von Willebrand disease (vWD), the most common inherited bleeding disorder in humans, results from abnormalities in the plasma clotting protein von Willebrand factor (vWF). Severe (type III) vWD is autosomal recessive in inheritance and is associated with extremely low or undetectable vWF levels. We report a method designed to distinguish mRNA expression(More)
The evidence for the promising potential for derivatives of Vitamin D (deltanoids) in the treatment of myeloid leukemias is increasing, but currently is not matched by the understanding of the precise mechanisms by which these anti-neoplastic effects are achieved. Unlike solid tumors in which growth retardation by deltanoids appears to result from(More)
Despite progress in understanding the biology of acute myeloid leukemia (AML), and despite advances in treatment, the majority of patients with AML die from the disease. The observation that Vitamin D can induce AML blast cells in vitro to differentiate along the monocytic lineage was made 30 years ago; however, it remains to translate this into a(More)
Acute myelogenous leukemia (AML) is a disease characterized by dysregulated cell proliferation associated with impaired cell differentiation, and current treatment regimens rarely save the patient. Thus, new mechanism-based approaches are needed to improve prognosis of this disease. We have investigated in preclinical studies the potential anti-leukemia use(More)
We have found a single 4p+ chromosomal abnormality, 46,XX, -4, +der(4)t(3;4)(q13.3;p16), in a patient with an unusual B cell leukemia of mature phenotype characterized by a high white cell count, tartrate-resistant acid phosphatase-positive malignant cells, splenic white pulp proliferation, and a serum IgM monoclonal gammopathy. The malignant cells were(More)
The co-existence of spontaneously arising myeloid and lymphoid malignancies in the same patient is rare, and is thought to be mainly due to chance. We describe a patient presenting simultaneously with chronic lymphocytic leukemia (CLL) and myelodysplasia (MDS). Histological, flow cytometric, chromosomal and fluorescent in situ hybridization (FISH) studies(More)
BACKGROUND Optimal cytoreductive surgery combined with intraoperative hyperthermic chemoperfusion (IHCP) is a therapy that potentially could improve survival in a select group of patients with advanced ovarian cancer. The purpose of this study was to review the results of cytoreductive surgery and IHCP for advanced ovarian cancer and to identify factors(More)
