Yet the organizational principles that govern these events, and their disruption in disease, remain poorly understood. Here, I will introduce several of our recent work in understanding cell and extracellular matrix (ECM) mechanics, as well as their mechanical interactions in 3D. I will then focus on discussing a recent progress to map the spatial and temporal evolution of positions, motions, and physical characteristics of individual cells throughout a growing mammary cancer model. Compared with cells in the tumor core, cells at the tumor periphery and the invasive front are found to be systematically softer, larger and more dynamic. These mechanical changes are shown to arise from supracellular fluid flow through gap junctions, suppression of which delays transition to an invasive phenotype. Together, these findings highlight the role of spatiotemporal coordination of cellular physical properties in tissue organization and disease progression. If time allows, I will also discuss our recent progress in demonstrating impact of cell mechanics in cell and tissue biological functions.\u003Cbr \/\u003E\r\n\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u0022Biomechanical Imaging of Cells, Extracellular Matrix, and Cancer Invasion in 3D\u0022 - Ming Guo, Ph.D. - Massachusetts Institute of Technology"}],"uid":"27195","created_gmt":"2022-01-25 18:38:56","changed_gmt":"2022-04-05 16:06:53","author":"Colly Mitchell","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2022-04-14T17:00:00-04:00","event_time_end":"2022-04-14T18:00:00-04:00","event_time_end_last":"2022-04-14T18:00:00-04:00","gmt_time_start":"2022-04-14 21:00:00","gmt_time_end":"2022-04-14 22:00:00","gmt_time_end_last":"2022-04-14 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1292","name":"Parker H.
