ABSTRACT
BACKGROUND:
In vitro culture condition and culture efficiency are different in reported umbilical cord-derived mesenchymal stem cells, and lacked of unified standards. Different derived mesenchymal stem cells have different biological properties. Therefore, it is very necessary to establish a simple and high-performance culture system for umbilical cord-derived mesenchymal stem cells.OBJECTIVE:
To observe the growth state of human umbilical cord-derived mesenchymal stem cells in different culture systems in vitro and adenovirus infection efficiency.METHODS:
Mesenchymal stem cells were separated from healthy full-termed delivery fetus using collagenase digestion method and purified by adherent culture. These cells were cultured and amplified in DMEM (low glucose), MesenPRO RS~(TM) Medium and STEMPRO~(R) MSC SFM in vitro. The 3-5 passage mesenchymal stem cells were infected by the Ad5-EGFP, Ad5/11-EGFP, Ad5/35-EGFP as multiplicity of infection (MOI)=1, 10, 100. Viral infection and green fluorescence expression were observed at post-infection 24, 56 and 72 hours using inverted fluorescence microscope. RESULTS ANDCONCLUSION:
The cell morphology in STEMPR~(R) MSC SFM was different from other two culture system and these cells were not easy to adherent after trypsin digestion. Cell doubling time in the MesenPRO RS~(TM) Medium was shorter than other two groups. Mesenchymal stem cells were infected by Ad5/35-EGFP with higher efficiency than other two kinds of adenovirus, but part of cells appeared apoptosis. The infection efficiency of Ad5/11-EGFP was highest. The fluorescence intensity was gradually increased with increased MOI.
