ABSTRACT

Lymph node mapping, a hotspot in oncology and surgery in recent years, has been successful-ly used in the discovery and resection of the metastatic lymph nodes in patients with melanoma and breast cancer. For the complex of lymphatic drainage and the defect of tracers, lymph nodes mapping is still under investigation. As a new type of nano-materials, the quantum dots are used widely, the tumor lymph node mapping.

ABSTRACT

Objective To explore a safe and high efficiency way of gene transfection of autocrine motility factor(AMF) in order to provide experimental basis for transplantation of myoblasts carrying AMF gone. Methods Sprague Dawley rat myoblasts were cultured, purified, proliferated and immunohisto-chemically verified. Then, the myoblasts were transfected with AMF and eGFP (enhanced green fluores-cent protein) gene by FIV (feline immunodeficiency virus). Fluorescence microscope and laser scanning confocal microscope were employed to detect eGFP so as to verify positive transfection rate. Expression of AMF was detected by immunohistochemical method. Results Myoblasts with 98% purity could he ob-tained after two weeks of primary culture and purification. Positive transfection rate reached 90.4% when MOI (multiplicity of infection) was 100 (P <0.01). The transfected AMF gene could express normally. Conclusions Explant culture is a proper way in rat myoblast culture. Meanwhile, AMF gene can he effectively transfected into rat myoblast and well expressed via FIV.
