Abstract

Several techniques have been devised for the dissociation of tissues for primary culture. These techniques can affect the quantity and quality of the isolated cells. The aim of our study was to develop the most appropriate method for the isolation of human umbilical cord-derived mesenchymal (hUCM) cells In the present study we compared four methods for the isolation of hUCM cells three enzymatic methods collagenaserhyaluronidasettrypsin (CHT) collagenasertrypsin (CT) and trypsin (Trp) and an explant culture (Exp) method The trypan blue dye exclusion test the water-soluble tetrazolium salt-I (WST-1) assay. flow cytometry, alkaline phosphatase activity and histochemical staining were used to evaluate the results of the different methods. The hUCM cells were successfully isolated by all methods but the isolation method used profoundly altered the cell number and proliferation capacity of the isolated cells. The cells were successfully differentiated into adipogenic and osteogenic lineages and alkaline phosphatase activity was detected in the hUCM cell colonies of all groups Flow cytometry analysis revealed that CD44 CD73. CD90 and CD105 were expressed in all groups while CD34 and CD45 were not expressed The expression of C-Vot in the enzymatic groups was higher than in the explant group, while the expression of Oct-4 was higher in the CT group compared to the other groups We concluded that the collagenaseArypsin method of cell isolation yields a higher cell density than the others These cells expressed a higher rate of pluripotent cell markers such as C-kit and Oct-4. while the explant method of cell isolation resulted in a higher cell proliferation rate and activity compared to the other methods. rc., The Society for In Vitro Biology 2012.
