Stem Cells & the Immune System: At the Crossroads of Regeneration
Nov 3 @ 11:00 am – 5:00 pm


The IRM is excited to announce that we are partnering with the Institute for Immunology (IFI) for our fall 2021 symposium, Stem Cells & the Immune System: At the Crossroads of Regeneration. This hybrid in-person/virtual event will feature external speakers and Penn scientists discussing a rapidly emerging question: how does the immune system influence regeneration throughout the body?

Recent studies have pointed to a role for the cells of the immune system in modulating stem cell activity in a number of different tissues: T cells infiltrating neurogenic niches; inflammation mediating alveolar regeneration; macrophages providing transient muscle stem cell niches and more. Our fall symposium will explore these and related topics, focusing on the impact on stem cell biology.

Penn/CHOP faculty, postdocs, students, and staff are invited to join us in person in the Smilow Rubenstein Auditorium and Commons. Need directions to Smilow? Click here.

Lightning talks

Students and postdocs: we are looking for lightning talk presenters! Lightning talks are 90 second, 1 slide “pitches” of your work to the gathered audience. If you are conducting research into an area related to our symposium theme, submit an abstract to by Friday, October 22 at 5 PM. Abstracts must include a title, authors and affiliations, and no more than 250 words describing the research.

COVID-19 Information

In compliance with all University of Pennsylvania and City of Philadelphia guidelines, this symposium is subject to the following COVID-19 procedures:

  • All in-person attendees must be vaccinated against COVID-19. You must attest to your vaccination status on the registration form. Please attend virtually if you are not vaccinated or do not wish to disclose your status.

Retreat 2022 @ Houston Hall
Jan 18 @ 1:00 pm – 5:00 pm












Please save the date for the IRM’s annual retreat, which will be held on January 18, 2022 from 1-5 PM in Houston Hall! We hope to see you all for this in-person­ afternoon of highlights from IRM labs, discussion about future research initiatives, and welcoming of new IRM faculty. The IRM retreat is open to any faculty, staff, postdocs, and students from Penn/CHOP interested in regenerative medicine research.

By popular demand, we are again inviting faculty interested in starting new collaborations to present short “pitches” about their ideas. At our last retreat, these talks generated a lot of discussion and positive feedback, and the IRM was able to offer funding for initial experiments.

What we are looking for

A 3-slide, 5-minute presentation about an idea, technique, or topic you would like to explore with other IRM researchers. These could be things you have been dreaming about for a while or entirely new areas that might benefit from the wide range of expertise in the IRM. You don’t need to have a collaborator in mind; all you need is an idea you want to share with the group.

Similar to last year, the IRM plans on devoting initial pilot funding to collaborations stemming from these discussions.

If you are interested

Send Chris Yarosh ( a one paragraph description of your planned presentation by Monday, December 20. Please include a brief description of the idea you want to discuss and why you think a new collaboration within the IRM could help get your project off the ground

Please mark your calendars for Jan 18!
