Chinese Journal of Clinical and Experimental Pathology 2015;(10):1127-1130
Purpose To study the expression of metastasis suppressor gene (KAI1/CD82) and cell adhesion molecules(CD44v6) in human laryngeal squamous cell carcinoma ( LSCC) and its clinical significance, and to investigate their relationship. Methods EnVi-sion immunohistochemistry was used to detect the expression of KAI1/CD82 and CD44v6 protein in 64 cases of LSCC tissues and 15 ca-ses of normal laryngeal mucosa ( NLM) tissues. Results The positive rate of KAI1/CD82 in LSCC tissues ( 37. 50%) was signifi-cantly lower than that of the NLM tissues(86. 67%) (P=0. 031), and the positive rate of CD44v6 in LSCC tissues(75. 00%) was significantly higher than that of the NLM tissues(26. 67%) (P=0. 011). The expression of KAI1/CD82 was associated with clinical stages, grade of tumor differentiation, neck lymph node metastasis ( P<0. 05 ) while not related with age, sex and prognosis ( P>0. 05). And CD44v6 with grade of tumor differentiation, neck lymph node metastasis and prognosis (P<0. 05), but not with age, sex and clinical stages (P>0. 05). In addition, KAI1/CD82 expression was negatively correlated with CD44v6 expression (rs = -0. 504, P=0. 036). Conclusion KAI1/CD82 and CD44v6 are mutually inhibited in the tumorigenesis, progress, invasion and metastasis, and detection of the expression of KAI1/CD82 and CD44v6 may be helpful for judging the biological behaviors of LSCC.

BACKGROUND:Rabbit bone marrow mesenchymal stem cels as a kind of adult stem cels with strong proliferation and multilineage differentiation potential exhibit a tremendous application potential in tissue engineering and biological therapy.
OBJECTIVE:To in vitro culture, proliferate and identify rabbit bone marrow mesenchymal stem cels and to observe cel biological characteristics.
MEHTODS:Bone marrow of rabbits was extracted under sterile conditions to separate bone marrow mesenchymal stem cels using the whole bone marrow adherence method and Percol density gradient centrifugation method. Afterwards, the cels were purified and proliferated using differential adherence method. Morphology and growth pattern of cels were observed under microscope, and expression of cel surface antigen markers was detected by flow cytometry.
RESULTS AND CONCLUSION:Rabbit bone marrow mesenchymal stem cels presented with short adherent time and fast growth. After passage and purification, impurities cel counts were decreased. Primary cels presented with triangular, fusiform and spindly shapes. Passage 5 cels with single shape showed the typical polar swirling growth, and could not express CD34 and CD45, but expressed CD29 and CD44. These findings indicate that the cels cultured using the whole bone marrow adherence method and Percol density gradient centrifugation method possess stem cel characteristics in morphology, surface markers and multilineage differentiation, which have been identified as bone marrow mesenchymal stem cels by flow cytometry.
