摘要:

背景:胎盘中含有丰富的细胞群,因其中CD34+细胞含量高而受到越来越多学者的关注,有望成为临床造血干细胞移植治疗血液病及其他恶性疾病的新来源。
目的:探索胎盘来源细胞的数量、集落形成能力及其与母体的嵌合程度。
方法:采用健康足月剖腹产妇的胎盘,灌注法及组织块消化法收集胎盘中细胞;流式细胞仪检测胎盘及脐血中CD34+细胞比例;培养细胞集落,定期观察集落形态并计数;序列特异性引物PCR扩增技术及序列特异性寡核苷酸探针方法检测胎盘、脐血和母亲外周血的HLA类型;短串联重复PCR方法检测胎盘细胞、脐血细胞和母亲外周血细胞的嵌合情况。
结果与结论:胎盘中CD34+细胞数量明显优于脐血,且胎盘具有体外多种集落形成能力,集落形成良好,同时胎盘提取细胞中含有母体来源成分。提示胎盘中细胞数量及其基本生物学特性使其有潜力成为临床造血干细胞移植的新来源。

Abstract:

BACKGROUND: There are abundant cell populations in the placenta that attracts more and more attentions because of high content of CD34+ cells. It is expected to become a new source of hematopoietic stem cells for the treatment of hematologic diseases and other malignant diseases.

 
OBJECTIVE: To investigate the amount of cells derived from placenta, their colony forming ability, and their chimerism analysis.
METHODS: Five placentas obtained from five healthy full-term cesarean women were treated with perfusion method and tissue digestion for the cell collection. Flow cytometry was used to detect the proportion of CD34+ cells in the placenta and cord blood, followed by the culture of cell colonies as well as regular observation of cell morphology and counting. PCR amplification with sequence-specific primers and sequence-specific oligonucleotide probes were used to examine HLA type of placenta, umbilical cord blood, and maternal peripheral blood; Short tandem repeat PCR was used for chimerism analysis.
RESULTS AND CONCLUSION: There were more CD34+ cells in the placenta than in the umbilical cord blood. The placenta had good ability to form multiple colonies in vitro, and there were maternal source components in the placenta. It is concluded that the amount of cells in the placenta and their biological functions exhibit the potential use of placenta as a new source of hematopoietic stem cells.
