SenNet 2024 CODCC Supplement Abstract The purpose of the Supplement is to further the CODCC Administrative Core (Sub-Section C: Administrative Core: Including Consortium Coordination & Outreach) in three areas: 1. integration and expansion of murine activities and additional awards across the consortium, 2. management and growth of the comprehensive, nationwide, undergraduate scientific internship award program in cellular senescence, 3. expanding opportunities to gather, in person, the consortium and pharmaceutical companies and related biotechnology businesses, focused on cellular senescence drug discovery and manufacture. Given the expansion of the consortium focused on murine and additional single cell data platforms, additional support and coordination will be required to handle the rapid growth in the development of the broader overall SenNet eco-system. This includes coordination with other single cell platforms at a larger scale to best serve the expanded SenNet Consortium adding substantive murine focus, combined murine and human foci, and the broader research community. Internships will allow learning valuable new skills across the scientific research spectrum and gain experience in an educational lab environment. During the internship program, students will conduct cutting-edge research, greatly expanding their knowledge of biology and data analysis. Students will develop various skills throughout the summer. CODCC received significant input in year two in working groups and from NIH regarding the consortium’s interest in meeting in-person more often, and particularly in focused areas among awards and outside parties with shared interest. These interests also cover senescence biology relevant to pharmaceutical development and manufacture. Following through on this will require additional management of meetings, workshop/panels/working groups, & data-thons and hackathons. To achieve these aims will also require expansion of communication and engagement to other common fund consortia, among the vendor ecosystem, and to the public interested in the science of Cellular Senescence and its human impact.
