Impact of viable CD45 cells infused on lymphocyte subset recovery after unrelated cord blood transplantation in children
2010
International audience; We studied lymphocyte recovery in 88 children who consecutively underwent unrelated cord blood transplantation for malignant (n = 64) or nonmalignant (n = 24) diseases. All children but 3 received myeloablative conditioning regimens with pretransplant antithymocyte globulin. Median age was 5.6 years (0.1-18 years) and median follow-up was 40 months (10-136 months). The median dose of infused viable CD45(+) cells (vCD45) was 3.35 × 10(7)/kg with a ratio infused vCD45/collected total nucleated cell at 0.46. Immunologic endpoints were: time to achieve CD3(+) >500 and 1500/mm(3), CD4(+) >500/mm(3), CD8(+) >250/mm(3), CD19(+) >200/mm(3), natural killer >100/mm(3). These e…
Presence of endothelial progenitor cells, distinct from mature endothelial cells, within human CD146+ blood cells.
2006
SummaryCD146 is an adhesion molecule present on endothelial cells throughout the vascular tree. CD146 is also expressed by circulating endothelial cells (CECs) widely considered to be mature endothelial cells detached from injured vessels. The discovery of circulating endothelial progenitor cells (EPCs) originating from bone marrow prompted us to investigate whether CD146 circulating cells could also contains EPCs. We tested this hypothesis using an approach combining elimination of CECs by an adhesion step, followed by immunomagnetic sorting of remaining CD146+ cells from the non adherent fraction of cord blood mononuclear cells. When cultured under endothelial-promoting conditions, these …
