Background: Circulating endothelial cells (CECs), originated form endothelial progenitors (EPCs) are mature cells not associated with vessel walls and detached from the endothelium. Normally, they are present in insignificant amounts in the peripheral blood of healthy individuals. On the other hand, elevated CECs and EPCs levels have been reported in the peripheral blood of patients with different types of cancers and other diseases. Objective: This review aims to provide an overview on the characterization of CECs and EPCs, to describe isolation methods and to identify the potential role of these cells in hematological diseases and hematopoietic stem cell transplantation. Methods: We performed a detailed search of peer-reviewed literature using keywords related to CECs, EPCs, allogeneic hematopoietic stem cell transplantation, and hematological diseases (hemoglobinopathies, hodgkin and non-hodgkin lymphoma, acute leukemia, myeloproliferative syndromes, chronic lymphocytic leukemia). Results: CECs and EPCs are potential biomarkers for several clinical conditions involving endothelial turnover and remodeling, such as in hematological diseases. These cells may be involved in disease progression and in the neoplastic process. Moreover, CECs and EPCs are probably involved in endothelial damage which is a marker of several complications following allogeneic hematopoietic stem cell transplantation. Conclusion: This review provides information about the role of CECs and EPCs in hematological malignancies and shows their implication in predicting disease activity as well as improving HSCT outcomes.

Matched Sibling

Abstract Abstract 4348 Background Hematopoietic stem cell transplantation (HSCT) from matched sibling donor is the standard first-line treatment for children with severe aplastic anemia (SAA). However, the management of SAA lacking a suitable donor remains a great challenge. For those children, HSCT using unrelated donor or mismatched related donor could be a therapeutic alternative. The purpose of this study is to evaluate the outcome in children with SAA who received HSCT from donors other than matched sibling. Patients and Method Between March 2003 and July 2009, 17 patients received HSCT from alternative donors (AD) at Asan Medical Center. We reviewed their medical records and analyzed their transplant-related parameters and outcome. Results Of a total of 17 patients, 11 were male and the median age at HSCT was 9.0 years, ranging from 3.0 to 16.7 years. Four patients had Fanconi anemia and 13 had acquired SAA including 2 who developed SAA after liver transplantation. Donors included unrelated bone marrow (U-BM) in 5, unrelated peripheral blood (U-PB) in 6, unrelated cord blood (U-CB) in 2 and related haploidentical peripheral blood (H-PB) in 4. Of 17 patients, 15 (88%) achieved sustained engraftment. Of 15 with engraftment, only 1 patient who received HSCT from U-CB died of severe GI GVHD and the other 14 patients remain on stable normal counts without transfusion support. All 2 patients (1 U-BM, 1 H-PB) who failed to engraft were dead despite DLI or 2nd HSCT. With a median follow-up of 31.9 months, the Kaplan-Meier estimated overall survival at 2 years was 76.6%. Conclusion In children with SAA, HSCT from AD including haploidentical family donor could be considered as a treatment option if the patients have no matched sibling donor. Given the limitation of this study such as small number of patients and short follow-up period, further trial will be necessary. Disclosures: No relevant conflicts of interest to declare.
