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.
