Signals Detected By In Vivo Imaging System 2 Months After Bone Marrow In this study, we track systemically transplanted allogeneic bone marrow mesenchymal stem cells (bmscs) in normal rats through bioluminescence imaging (bli) in real time. ex vivo organ imaging, immunohistochemistry (ihc), and rt pcr were conducted to verify the histological distribution of bmscs. Wounding and imaging experiments preferably should be performed at least 2 months after the bm transplant, when complete marrow engraftment and bone marrow cell production has resumed.
In Vivo And Ex Vivo Analysis Of Peripheral Blood And Bone Marrow Cells The cumulative evidence, however, highlights a third important function of bone marrow in whole body homeostasis, namely its role in repair following injury of distant sites, especially the. Radiation induced mri signal changes in bone marrow are the earliest detectable changes in bone. their severity correlates with increasing radiation dose. pathology 1 st week: decreased marrow cellularity with oedema and haemorrhage 2 nd week: increased marrow cellularity due to influx from non irradiated areas. Intravital imaging enabled detailed visualization of single sca 1 , c kit , lineage − (skl) cell migration to bone marrow niches and subsequent proliferation to reconstitute hematopoiesis. Ex vivo imaging of the recipient mice at 24 h after bmt confirmed nirf signal distribution in the tissues suggested by in vivo imaging (fig. 3c). significant nirf signals were detected in bm and the reticuloendothelial system, but not in the gi tract (fig. 3c).

We demonstrated the growth and survival of ibmscs mcl in the aclt oa mice by examining enhanced intensive signals through ivis imaging after 1 month implantation (figure 5), indicating their continued proliferation under in vivo conditions. The overall goal of this study was to visualize bone marrow derived microglia infiltrating the brain during neuroinflammation by in vivo optical imaging. to achieve this goal, we made transplanted bone marrow derived microglia detectable in mice, by having them express gfp or firefly luciferase. Bioluminescence imaging (bli) was used to track cell migration and survival in vivo for 4 weeks. bli showed preferential homing of bmmcs to hearts with i r injury compared with sham hearts within the first week following cell injection. In vivo bioluminescence imaging showed an early signal increase in both bmc groups at day 7, followed by a nonsignificant trend (p =0.203) toward improved bmc survival in the subacute bmc group that persisted until the bioluminescence imaging signal reached background levels after 42 days.
