5.Immune function regulation by bone marrow mesenchymal stem cells in rats undergoing heart transplantation
Chinese Journal of Tissue Engineering Research 2016;20(50):7494-7499
BACKGROUND:Heart transplantation is an effective method for treatment of end-stage heart failure, but immune rejection that seriously impact therapeutic effacicy is easy to occur after transplantation. OBJECTIVE:To investigate the regulatory effect of bone marrow mesenchymal stem cel s on the immune function of rats undergoiong heart transplantation. METHODS:Twenty Lewis rats were enrol ed as donors, and 20 Wistar rats as recipients. Heart transplantation models were established in the Wistar rats. These 20 model rats were randomized into cel transplantation and control group with 10 rats in each group. Forty-eight hours after heart transplantation, rats in the cel transplantation group were given bone marrow mesenchymal stem cel suspension (1 mL, 2×108 cel s/L) via the tail vein, while rats in the control group were given normal saline in the same dose. Then, the expression levels of serum interleukin-2, interleukin-10 and percentage of CD4+, CD8+, CD4+/CD8+, CD4+CD25high, CD4+CD25high Foxp3+T cel s in the venous blood were detected in the two groups at 7 days after cel transplantation. Additional y, rat myocardial tissues were taken and observed pathological y. RESULTS AND CONCLUSION:The survival time of the cel transplantation group was significantly longer than that of the control group (P<0.05). The expression level of interleukin-2 showed no significant difference between the two groups (P>0.05), but the level of interleukin-10 in the cel transplantation group was significantly higher than that in the control group (P<0.05). Compared with the control group, the percentage of CD4+/CD8+, CD4+CD25high, CD4+CD25high Foxp3+and CD4+T cel s was significantly higher, and the percentage of CD8+T cel s was significantly lower in the cel transplantation group (P<0.05). Histopathological findings showed that there were a smal amount of infiltrated lymphocytes in the cel transplantation group with the presence of slight bleeding and edema, and these inflammatory reactions were milder than those in the control group. These findings indicate that bone marrow mesenchymal stem cel transplantation can effectively reduce the rejection in rats undergoing heart transplantation.
6.Expression and clinicopathological significance of Yes-associated protein in endometrial cancer
Journal of International Oncology 2015;42(11):828-831
Objective To study the expression of Yes-associated protein(YAP) in endometrial cancer and its clinical pathological significance.Methods Immunohistochemieal MaxVisionTM method was used to detect the expression of YAP in 289 cases of endometrial cancer, and its relationship with clinical pathological features and prognosis were analyzed.Results The expression rate of YAP in type Ⅱ endometrial cancer was higher than that in typeⅠendometrial cancer (87.0% vs.55.1%, x2 =16.340, P < 0.001).In typeⅠendometrial cancer, the expression rate of YAP in G1 cases was lower than that in G2-G3 cases (51.6% vs.80.0%, x2 =8.549, P =0.005), not associated with menopausal status (x2 =0.045, P =0.831), FIGO stage (x2 =0.976, P =0.323), lymph vascular space invasion (x2 =0.000, P =1.000), lymph node metastasis (x2 =0.976, P =0.323) and ER status (x2 =3.318, P =0.069).In typeⅡendometrial cancer, the expression of YAP was not significantly associated with menopausal status (x2 =0.305, P =0.581), FIGO stage (x2 =2.395, P =0.122), lymph vascular space invasion (x2 =1.441, P =0.230), lymph node metastasis (x2 =1.351, P =0.245) and ER status (x2 =0.000, P =1.000).Log-rank test analysis showed that YAP high-expression was associated with a significantly worse overall survival in typeⅠ endometrial cancer (x2 =14.023, P < 0.001), but YAP expression was not an independent prognostic factor.Conclusion YAP shows high expression in endometrial cancer.It is associated with histological grade and prognosis of typeⅠ endometrial cancer.
7.Dipeptidyl peptidase-Ⅳ : potential implications beyond blood glucose control
Chinese Journal of Clinical Nutrition 2015;23(4):244-249
Dipeptidyl peptidase-Ⅳ (DPP-Ⅳ/CD26,EC 3.4.14.5),a transmembrane serine polypeptidase,is widely distributed and has diverse effects.As a dipeptidase,DPP-Ⅳ/CD26 could not only regulate the activity of many peptide hormones,neuropeptides,cytokines and growth factors via its peptidase function,but also mediate cell-matrix and cell-cell contact through interactions with other molecules or proteins as a surface antigen.DPP-Ⅳ/CD26 plays a regulatory role in immune activation,inflammation and tumorigenesis.This review covers the structure,distribution,physiological functions and changes in pathological state of Dpp-Ⅳ/CD26.
8.Stomach cancer stem cells:isolation, identification and characteristics
Chinese Journal of Tissue Engineering Research 2015;(32):5188-5192
BACKGROUND:With the in-depth study of cancer stem cels, increasing evidence has shown that cancer stem cels are the reason for cancer metastasis and recurrence, and therefore it is of great significance to isolate and identify cancer stem cels that can elucidate the pathogenesis of cancer and development of anticancer drugs.
OBJECTIVE: To isolate and culture gastric cancer stem cels and then to detect its biological characteristics.
METHODS: Cancer tissues from 16 patients with gastric cancer were cultured using adherent method and enzymic digestion methods to isolate gastric cancer stem cels. The cel morphology was observed under inverted microscope to drawn out growth curves. Osteogenic and adipogenic ability of cels were also detected.
RESULTS AND CONCLUSION: Gastric cancer stem cels were isolated successfuly by both two methods. Under the microscope, the cels were fusiform- or polygon-shaped. At confluence, the cels grew in a vortex or radial manner. The cel growth curve showed that 1-3 days were latent period, 4-9 days were logarithmic growth phase, and over 10 days were growth plateau phase. Flow cytometry results showed that passage 3 gastric cancer stem cels highly expressed CD90, CD29, CD44, but lowly expressed CD34, CD45 and HLA-DR. After osteogenic induction, calcified nodules were clearly visible in the gastric cancer stem cels at passage 3; after adipogenic induction, bright and tiny fat droplets were seen in the cytoplasm. These findings indicate that cancer stem cels exist in the gastric cancer tissues, and have similar morphology, biological property and multipotent differentiation ability to normal cels, which are probably involved in gastric cancer occurrence and development.
