Report on the 2nd Spatial Genome Organisation Conference (SGO25)
31 October - 3 November 2025, Riviera Maya, Mexico
Conference Chairs: Matthias Altmeyer, Irene Chiolo, and Karim Mekhail
The 2nd Spatial Genome Organisation Conference brought together researchers studying nuclear architecture, genome topology, transcriptional regulation, DNA repair, and biomolecular condensates. The meeting featured an interdisciplinary program exploring how the spatial organization of the genome influences key nuclear processes and cellular responses to stress. Through a series of thematic sessions, presentations highlighted emerging principles connecting genome architecture with replication, transcription, DNA repair, and chromatin regulation.
Several sessions focused on the physical and topological constraints that shape chromosome organization during DNA replication and genome maintenance. New insights were shared on how DNA topology, supercoiling, and chromosomal catenation influence chromosome folding and replication processes. These studies emphasized the importance of chromosome structural maintenance complexes and topoisomerases in coordinating replication with genome architecture, and indicated that the spatial organization of chromatin domains actively helps manage replication stress and preserve genome stability.
Another key theme of the meeting was the role of nuclear compartments and biomolecular condensates in organizing genome function. Presentations highlighted that dynamic protein and RNA condensates can serve as regulatory hubs that coordinate transcription, DNA repair, and RNA metabolism. New imaging and biochemical techniques revealed how these assemblies form, dissolve, and interact with chromatin in response to cellular signals and DNA damage. These findings support an increasing view that condensate formation is an important mechanism by which cells spatially organize nuclear activities and integrate multiple signaling pathways.
The conference also highlighted how genome instability results from disruptions to nuclear organization during replication stress, chromosome mis-segregation, and mitotic errors. Studies examining micronuclei, chromosomal rearrangements, and DNA damage responses showed how structural changes in the genome can trigger inflammatory signaling and modify transcriptional programs. These observations further emphasize the strong connections between spatial genome organization, genome stability, and disease processes including cancer and aging.
Technological innovation was another key focus of the meeting. New high-resolution genomic mapping techniques, single-molecule imaging methods, and computational models are providing more detailed views of chromosome interactions and nuclear structure. These tools help researchers link genome organization to gene regulation and DNA repair processes across various spatial and temporal scales.
The meeting also promoted active participation among early-career scientists through poster sessions and networking events, creating opportunities for discussion and collaboration. Overall, the conference effectively combined advances in chromatin biology, genome stability, and nuclear organization, emphasizing the significance of spatial genome architecture as a unifying framework for understanding genome function in health and disease.
The conference will bring together scientists working to better understand nuclear and genome organisation in various organisms, tissues, and cell states.
Conference sessions will cover topics related to:
● Nuclear and subnuclear structure and function
● Nuclear organisation and chromosome topology in gene expression
● Nuclear organisation and chromosome topology in DNA replication and repair
● Crosstalk between transcription and repair
● Impact of nuclear and genome organisation on genome editing
● Genome editing technologies in the study of nuclear and genome structure and function
● Nuclear bodies including the nucleolus, Cajal bodies, speckles, PML bodies
● Constitutive and induced phase separation in the nucleus
● Topologically associated domains and transcription in genome control
● Signalling cues, cellular states and genome organisation
● Genome organisation in pluripotency and during differentiation
● Nuclear and genome structures in health, cancer, aging, and age-related diseases
● Chromatin loops and non-canonical nucleic acids structures in genome expression and stability
● Spatial genome organisation: from the bench to the bedside
Workshops will cover: Technical advances in the study of nuclear and genome organisation; The next frontiers in spatial genome organisation and its connection to health and disease; How to publish in the era of spatial genome organisation?

This conference is of interest to researchers and scientists from academia and industry who are seeking to understand the basic principles of spatial genome organisation and how their disruption impacts health and disease, all within a beautiful and natural setting. Those interested in learning or developing new technologies that help reveal more of the secrets of spatial genome organisation should both benefit from and greatly enrich the conference. Attendees typically have a background in the basics of genetics, nuclear organisation, genome functions, microscopy, and sequencing.
This conference provides a unique opportunity for trainees interested in spatial genome organisation and the latest advances in this rapidly growing area of research from established and emerging leaders in the field. The conference also provides numerous scientific and social networking opportunities for trainees to discuss their research activities and career plans with others in the field.
