Figure 4. KCs isolated from old mice could attract more MSCs in vitro due to more inflammatory chemokines secretion.
A., Identification of KCs isolated from mice liver. (a)Phenotype of KCs isolated from mice liver; (b) Cytoimmunofluorescence assay was done to identify KCs(CD68, green; nuclei, blue). (400×) B., Identification of MSCs isolated from mice bone marrow. (a), Phenotype of MSCs; (b), MSCs under fluorescent microscope; (c), Oil red O staining after adipogenesis differentiation; (d), Alizarin Red S staining after osteogenesis differentiation. (200×)C., Transwell migration assay was performed to detect MSCs migration to KCs. Migrated MSCs were stained by crystal violet. (200×) D., The quantification of migrated MSCs of C. E., Cytokines concentration in conditioned medium of KCs was detected by bioplex assay. Y-KCs, KCs from young mice; O-KCs, KCs from old mice; Y, young; O, old; Y+C, young+CCl4; O+C, old+CCl4. *P < 0.05.
