Objectives To track bone marrow stem cells (BMSCs) labeled by enhanced green fluorescent protein (EGFP) and superparamagnetic iron oxide ( SPIO ) -poly-L-lysine (PLL) compound by MRI in vitro for autotransplantation into pancreas of type 1 diabetes miniature pigs. Methods The BMSCs were isolated by density gradient centrifugation and attachment culture from type 1 diabetes minipigs' bone marrow. Expressional intensity of EGFP in BMSCs transfected lentivirus-EGFP with a multiplicity of infection Different magnetic resonance scanning protocols were carried out on various density BMSCs labeled by different concentration of SPIO in various time-point in vitro. Results When SPIO concentration was 25mg/L (count in Fe3 + ), the positive Fe3+ -labeling rate of BMSCs was 93. 1%. Most of SPIO particles in BMSCs' cytoplasm were observed in secondary lysosomes, but they were not detected in important organelle as cell nucleus. Comparing with gelatin the MRI of BMSCs labeled with SPIO in the condition with 1 ×104/ml cells density and 25 mg/L Fe3+ concentration in vitro, the signal intensity changes (△SI) after BMSCs labeled with SPIO 3 weeks and 6 weeks in TSE T1WI, TSE T2WI and FLASH T2 * WI sequences were 12%, 41%, 63% and 7%, 28%, 46% respectively (P ＜ 0.01 and P ＜ 0.05, respectively).Conclusions The data showed that the porcine BMSCs labeled with SPIO and EGFP could be traced successfully in vitro by MRI in the suitable sequences.

Objective To explore the effect of wild type or mutant parkin gene expression on the growth of human hepatocellular carcinoma cell line Huh-7. Methods The parkin (wild type or mutant) expression vector and empty vector were transferred into Huh-7 cell lines with LipofectAMINE 2000 reagents. The positive clones that expressed parkin gene stably were chosen by G418 and checked by reverse transcription-polymerase chain reaction (RT-PCR) to check the DNA sequences. The cytobiological behaviors of those positive clones were analyzed by cell proliferation assay and tumorigenesis in nude mice. Results Huh-7 cell lines that expressed wild type or mutant parkin gene stably were successfully established. The growth of wild type parkin-expressed cells was obviously inhibited compared with the control cells transfected with empty vectors(t= 3. 875, P= 0. 031).The volume of tumor formed by wild type parkin-expressing cells in nude mice was also significantly reduced (t=8. 228,P=-0. 003). Mutant parkin gene expression had a slight effect on the growth of Huh-7 cells in vitro and in vivo (P＞0.05). Conclusion The re-expression of wild type parkin gene can favor the malignant phenotype revision of Huh-7 cells. Therefore, it might be a good candidate for tumor suppressor gene associated with HCC.
