News and Updates from CAAT

Holiday Greetings!


Call for Abstract Submissions
The First Microphysiological Systems World Summit
May 30th - June 3rd 2022
 Hilton New Orleans Riverside, New Orleans, USA
Abstract Submission Deadline: January 31st, 2022, 11:59pm PST

Microphysiological System (MPS): cell culture systems replicating (patho-) physiology through engineered organ architecture and functionality. This includes especially 3D-(co-)cultures such as organoids, organ-on-chip models, and multi-organ models, as well as the technologies to engineer and analyze these systems.
Abstracts are invited on the topic of new developments in MPS and applications of MPS. Describe your newest developments: break-throughs, advantages, challenges and the field of applications.
Top scored abstracts will be selected for an oral presentation at one of 14 scientific sessions.
Abstract submission guidelines:
All abstracts will be evaluated and selected for oral or poster presentation by the MPS Scientific Advisory Committee
Abstracts must be in English and no more than 300 words (title, authors and references excluded)
Pictures, figures, attachments are not permitted
Include no more than three references
Please submit abstract following the link:
Make sure to select the top two sessions you abstract fits the best
Maximum two abstracts are allowed for one presenting author.
All presenters must be registered for the conference, if accepted

Our end of the year message:

The CAAT family was very busy in 2021. We celebrated our 40th anniversary, EBTC celebrated its 10th anniversary, we honored our departing deputy director Helena Hogberg with a special DNT Symposium, and welcomed our new deputy director Fenna Sille to our leadership core. We are working restless with several stakeholders to make the MPS World Summit a reality. We had several workshops, webinars, and plenty of virtual meetings. Many of them are available at our YouTube Channel.
Our own Alex Maertens even ran the Honolulu Marathon!


And like all families in 2021, we had ups and downs. But we thrived, thanks to your support: our friends, sponsors and partners. We hope 2022 brings more collaborations, and even more alternatives to animal testing.
Happy Holidays!!

The CAAT Team
