The full text of selected abstracts will be released to meeting attendees on 17 September 2025, one week prior to the start of the Annual Scientific Meeting. Any abstract-related content may not be published until the abstracts are released to attendees on 17 September 2025. Updated data, new graphics, and follow-up information to be presented during the Annual Scientific Meeting is embargoed until the day of the presentation.

Poster Printing in Kumamoto

We recommend printing your poster before arriving to ISEH. If you prefer to print your poster in Kumamoto, our local organizing group has recommended the print shop below.

The web page is only available in Japanese, but you can use Google translate browser translation.

They have no English-speaking staff, but if presenters go directly to the shop, bring their data on a USB, point out the size they want and print on what materials, the staff should be able to provide support.

ISEH is committed to helping early-career investigators maximize their potential. In 2025 we are offering travel grants to eligible ISEH members who are PhD students or Post-doctoral fellows. Payout for travel grant recipients is contingent on their attendance at the ISEH Annual Scientific Meeting and their presentation of an accepted abstract as a poster or oral presentation. The travel grant application is only open during the first call for abstracts and is not available to late-breaking abstract submitters.

Here are some fantastic travel grant opportunities available for 2025.

ISEH and Paul S. Frenette Travel Grants

Technology and Innovation Travel Grants

This travel grant is given in honor of Ihor Lemischka, and will be given out for the ISEH 54th Annual Scientific Meeting.

Three of the submitted technology applications will be selected to present in the New Investigators Technology Session.

Developing Country Travel Grants

Our society firmly believes that the scientific community is stronger with the active participation and leadership of people with diverse identities, perspectives and backgrounds. As such, ISEH has established a Developing Country Travel Grant to promote accessibility of the ISEH meeting and community to scientists from developing countries who may not otherwise be able to attend. Travel grant applicants must submit an abstract to the ISEH meeting and work in one of the eligible countries, defined by ISEH as those in the World Bank tiers of low-income and lower-middle income or by the IMF as an Emerging and Developing Economy. Abstracts will be reviewed and scored on scientific merit, with the top scoring abstract(s) being prioritized. Funding is limited.

Criteria and requirements for the Developing Country Travel Grant:

Reside in countries defined by the World Bank as Low-income and Lower-middle Income Economies

Additional notes:

• While it is not required, we encourage you to join ISEH as a member.
• This travel grant is available to applicants in all all career stages.
