Collection of Peripheral Blood Stem Cells from Low-Weight Infants with Osteopetrosis and Its Clinical Signi-ficance / 实用儿科临床杂志

ABSTRACT

Objective To explore the safety of collection of peripheral blood stem cells(PBSCs) from low-weight infants with osteopetrosis(OP) and its clinical significance. Methods One case of low-weight infants with OP received PBSCs collection using a continuous-flow blood cell separator,and the safety of collection process was observed.The amount of monocyte cell(MNC) and CD34+ cell were noted and its clinical significance was analyzed.Results Low-weight infants with OP could tolerate collection process,the number of collection MNC and CD34+ cells were 10.06?108/kg,2.74?106/kg.Conclusion Adequate PBSCs can be collected from OP who need not be mobilized,thus can offer backup for graft failure.PBSCs collection from low-weight infants is safe.
