PG - 103-126 LID - 10.1007/978-1-0716-2744-0_9 [doi] AB - Cell communication network factor 2 (CCN2), also known as connective tissue growth factor (CTGF), is protein inducible in response to TGFbeta/Smad signal or the transcriptional activity of matrix metalloproteinase 3 (MMP3). We discovered that MMP3 in exosomes is transferable to recipient cells and then translocates into cell nuclei to transactivate the CCN2/CTGF gene. Exosomes and liposomes enable molecular transfection to recipient cells in vitro and in vivo. These small vesicles are surrounded by lipid membranes and carry proteins, RNA, DNA, and small chemicals. Here we define the exosome-based transfection as "exofection." In addition, spinfection increases the efficiencies of transfection, exofection, and viral infection, thus being compatible with various molecular transfer protocols. Here, we provide protocols, tips, and practical examples of transfection, spinfection, exofection, fluorescence microscopy, and luciferase assays to analyze the CCNs gene expression mechanisms.
