The cerebral cortex is the largest site of neural integration in the central nervous system. Concerted radial migration of newly born cortical projection neurons, from their birthplace to their final position, is a key step in the assembly of the cerebral cortex. The cellular and molecular mechanisms regulating radial neuronal migration in vivo are however still unclear. Recent evidence suggests that distinct signaling cues act cell-autonomously but differentially at certain steps during the overall migration process. Moreover, functional analysis of genetic mosaics (mutant neurons present in wild-type/heterozygote environment) using the MADM (Mosaic Analysis with Double Markers) analyses in comparison to global knockout also indicate a significant degree of non-cell-autonomous and/or community effects in the control of cortical neuron migration. The interactions of cell-intrinsic (cell-autonomous) and cell-extrinsic (non-cell-autonomous) components are largely unknown. In part of this thesis work we established a MADM-based experimental strategy for the quantitative analysis of cell-autonomous gene function versus non-cell-autonomous and/or community effects. The direct comparison of mutant neurons from the genetic mosaic (cell-autonomous) to mutant neurons in the conditional and/or global knockout (cell-autonomous + non-cell-autonomous) allows to quantitatively analyze non-cell-autonomous effects. Such analysis enable the high-resolution analysis of projection neuron migration dynamics in distinct environments with concomitant isolation of genomic and proteomic profiles. Using these experimental paradigms and in combination with computational modeling we show and characterize the nature of non-cell-autonomous effects to coordinate radial neuron migration. Furthermore, this thesis discusses recent developments in neurodevelopment with focus on neuronal polarization and non-cell-autonomous mechanisms in neuronal migration."}],"title":"Cell-autonomous gene function and non-cell-autonomous effects in radial projection neuron migration","language":[{"iso":"eng"}],"department":[{"_id":"GradSch"},{"_id":"SiHi"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","author":[{"last_name":"Hansen","full_name":"Hansen, Andi H","first_name":"Andi H","id":"38853E16-F248-11E8-B48F-1D18A9856A87"}],"supervisor":[{"full_name":"Hippenmeyer, Simon","last_name":"Hippenmeyer","orcid":"0000-0003-2279-1061","id":"37B36620-F248-11E8-B48F-1D18A9856A87","first_name":"Simon"}],"publication_status":"published","oa":1,"has_accepted_license":"1","project":[{"grant_number":"24812","_id":"2625A13E-B435-11E9-9278-68D0E5697425","name":"Molecular Mechanisms of Radial Neuronal Migration"}],"degree_awarded":"PhD","status":"public","doi":"10.15479/at:ista:9962","article_processing_charge":"No","date_created":"2021-08-29T12:36:50Z","date_published":"2021-09-02T00:00:00Z","month":"09","oa_version":"Published Version","date_updated":"2023-09-22T09:58:30Z","day":"02","type":"dissertation","related_material":{"record":[{"id":"8569","relation":"part_of_dissertation","status":"public"},{"relation":"part_of_dissertation","id":"960","status":"public"}]},"year":"2021","alternative_title":["ISTA Thesis"],"publication_identifier":{"issn":["2663-337X"]},"file_date_updated":"2022-09-03T22:30:04Z","page":"182","_id":"9962","publisher":"Institute of Science and Technology Austria"}
