The interpretation of fate‐mapping studies depends upon multiple assumptions: (i) that expression of cre recombinase has no effect on monocyte‐macrophage homeostasis, (ii) that tamoxifen is a neutral agonist, (iii) that life in an SPF animal facility reflects the normal life course o...
mice. We used an adult fate mapping mouse model to characterize turnover kinetics within the pancreatic resident macrophages under normal homeostasis and obese diabetic conditions. We demonstrate that islet resident macrophages show unique replenishment kinetics, with embryonic macrophages being gradually ...
Thus,barcoding enables high-resolution fate mapping in essentially all tissues in mice for which inducible Cre driver lines are available. Alternative methods include ex vivo cell barcoding, inducible transposon insertion and CRISPR鈥揅as9-based barcoding;currently allows combining non-invasive and cell-...
Fate-mapping intratumoral hypoxia We generated orthotopic breast tumors by transplanting MDA-MB-231 (or 4T1) fate-mapping cells into the mammary fat pad of mice followed by tumor resection at different time points (Fig. 4a and Supplementary Fig. 5a). To correlate fluorescence expression with intr...
摘要: With the new understanding that adult microglia in mice have embryonic origins and are maintained in situ throughout life, it has become pertinent to now understand how these unique cells differ from...关键词: Cx3cr1-CreER mice Flow cytometry In vivo/fate mapping Microglia Monocyte-...
We used fate mapping and AID(GFP) reporter mice to determine if AID expression in the mouse extends beyond lymphocytes. We discovered that AID(cre) tags a small fraction of non-lymphoid cells starting at 10.5 days post conception (dpc), and that AID(GFP+) cells are detectable at dpc 11.5...
In contrast to many macrophage populations, we show that microglia develop in mice that lack colony stimulating factor-1 (CSF-1) but are absent in CSF-1 receptor–deficient mice. In vivo lineage tracing studies established that adult microglia derive from primitive myeloid progenitors that arise ...
Transgenic mice harboring either the lacZ or the enhanced green fluorescent protein reporter genes under the transcriptional control of rhombomere-specific Hoxa2 enhancer elements were used to visualize rhombomere-derived domains. We labeled functionally identifiable vestibular projection neuron groups ...
We demonstrate the method using our well characterized Wnt1-CreER(T);mGFP mice by administering tamoxifen at embryonic day (E)8.5 via oral gavage followed by dissection at E12.5 and analysis by epifluorescence stereomicroscopy. We also demonstrate how to micro-dissect fate mapped domains for ...
Herein, we used various multicolor fate mapping systems to investigate the ontogeny and dynamics of lymph node (LN) FDCs in situ. We show that LN FDC networks arise from the clonal expansion and differentiation of marginal reticular cells (MRCs), a population of lymphoid stromal cells lining ...
