[Comparative characterization of mesenchymal stem cells from human umbilical cord tissue and bone marrow].

This study was purposed to compare the biological characteristics of umbilical cord-derived mesenchymal stem cells (UC-MSCs) and bone marrow-derived mesenchymal stem cells (BM-MSCs). The frequency of successful isolation, cell yield, colony-forming units-fibroblastics (CFU-F), proliferation capacity, immunophenotype and multi-differentiation potentials of UC-MSCs and BM-MSCs were determined by limiting dilution assay, flow cytometry, invert microscopy, RT-PCR and so on, the determined results were compared. The results showed that MSCs were successfully isolated from all the 36 portion of UC tissue and 8 portion of BM.

[Construction of recombinant adenovirus vector containing human survivin gene and its expression in dendritic cells].

The study was aimed to construct the recombinant adenovirus vectors containing human survivin gene, and to investigate their expression in transfected dendritic cells. Full length cDNA encoding survivin was obtained by PCR amplification from plasmid pcDNA3.0-survivin.

Isolation and characterization of human umbilical cord mesenchymal stem cells with hematopoiesis-supportive function and other potentials.

Background And Objectives: Adult bone marrow (BM) is the major source of mesenchymal stem cells (MSC) for cell therapy. However, aspiration of BM involves invasive procedures. We isolated MSC from human full term umbilical cord tissues (UC).
