We are grateful to our collaborators Monica Suelves and Miquel Angel Peinado at the IMPPC in Barcelona for the invitation to present our results of collaborative studies on epigenetic influences of the cell of origin of rhabdomyosarcoma.
Following this visit, the work of KellerLab-DrukerLab co-mentored HHMI medical student, M. Imran Aslam, entitled, "PDGFR reverses Eph signaling in alveolar rhabdomyosarcoma" was presented at the ESF-EMBO Symposium, “Molecular Biology &Innovative
Therapies in Sarcomas of Childhood and
Adolescence” organized by Beat Schaefer. This latter conference was in Putlusk, Poland, and was perhaps the best rhabdomyosarcoma and Ewing's sarcoma conference in 10-15 years. Many collaborations amongst all attendees were created.
