Open access resource for cellular-resolution analyses of corticocortical connectivity in the marmoset monkey.

ABSTRACT: Understanding the principles of neuronal connectivity requires tools for efficient quantification and visualization of large datasets. The primate cortex is particularly challenging due to its complex mosaic of areas, which in many cases lack clear boundaries. Here, we introduce a resource that allows exploration of results of 143 retrograde tracer injections in the marmoset neocortex. Data obtained in different animals are registered to a common stereotaxic space using an algorithm guided by expert delineation of histological borders, allowing accurate assignment of connections to areas despite interindividual variability. The resource incorporates tools for analyses relative to cytoarchitectural areas, including statistical properties such as the fraction of labeled neurons and the percentage of supragranular neurons. It also provides purely spatial (parcellation-free) data, based on the stereotaxic coordinates of 2 million labeled neurons. This resource helps bridge the gap between high-density cellular connectivity studies in rodents and imaging-based analyses of human brains.

Project description:Radiopharmaceutical dosimetry depends on the localization in space and time of radioactive sources and requires the estimation of the amount of energy emitted by the sources deposited within targets. In particular, when computing resources are not accessible, this task can be performed using precomputed tables of specific absorbed fractions (SAFs) or S values based on dosimetric models. The aim of the OpenDose collaboration is to generate and make freely available a range of dosimetric data and tools. Methods: OpenDose brings together resources and expertise from 18 international teams to produce and compare traceable dosimetric data using 6 of the most popular Monte Carlo codes in radiation transport (EGSnrc/EGS++, FLUKA, GATE, Geant4, MCNP/MCNPX, and PENELOPE). SAFs are uploaded, together with their associated statistical uncertainties, in a relational database. S values are then calculated from monoenergetic SAFs on the basis of the radioisotope decay data presented in International Commission on Radiological Protection Publication 107. Results: The OpenDose collaboration produced SAFs for all source region and target combinations of the 2 International Commission on Radiological Protection Publication 110 adult reference models. SAFs computed from the different Monte Carlo codes were in good agreement at all energies, with SDs below individual statistical uncertainties. Calculated S values were in good agreement with OLINDA/EXM 2.0 (commercial) and IDAC-Dose 2.1 (free) software. A dedicated website (www.opendose.org) has been developed to provide easy and open access to all data. Conclusion: The OpenDose website allows the display and downloading of SAFs and the corresponding S values for 1,252 radionuclides. The OpenDose collaboration, open to new research teams, will extend data production to other dosimetric models and implement new free features, such as online dosimetric tools and patient-specific absorbed dose calculation software, together with educational resources.

Project description:Following a certain type-specific number of mitotic divisions, terminally differentiated cells undergo proliferative senescence, thwarting efforts to expand different cell populations in vitro for the needs of scientific research or medical therapies. The primary cause of this phenomenon is the progressive shortening of the telomeres and the subsequent activation of cell cycle control pathways leading to a block of cell proliferation. Restoration of telomere length by transgenic expression of telomerase reverse transcriptase (TERT) usually results in bypassing of the replicative senescence and ultimately in cell immortalization. To date, there have not been any reports regarding immortalization of cells from common marmoset (Callithrix jacchus), an important non-human primate model for various human diseases, with the use of exogenous human TERT (hTERT). In this study, marmoset fibroblasts were successfully immortalized with transposon-integrated transgenic hTERT and expanded in vitro for over 500 population doublings. Calculation of population doubling levels (PDL) showed that the derived hTERT-transgenic lines had significantly higher proliferation potential than the wild-type fibroblasts, which reached only a maximum of 46 doublings. However, the immortalized cells exhibited differences in the morphology compared with the control fibroblasts and transcriptome analysis also revealed changes in the gene expression patterns. Finally, the karyotypes of all hTERT-transgenic cell lines showed various aberrations such as presence of extra Chromosome 17, isochromosome 21q, or tetraploidy. By single-cell expansion of the least affected monoclonal immortalized line, one sub-clonal line with normal karyotype was established, suggesting the possibility to derive immortal marmoset cells with normal karyotypes. The results of this study are an important step towards the development and optimization of methods for the production of immortalized cells from common marmoset monkeys.
