We advise all presenters to look at the TIPS FOR TALKS (548 kB) presentation and read these guidelines (39kB) before starting to prepare their talks. Science is in the detail. It is the lifeblood of science to discuss.

All invited talks are 20 minutes (20-30 slides) to allow 10 minutes discussion per talk.
All submitted talks are 10 minutes (10-15 slides) to allow 5 minutes discussion per talk.

Chairpersons will cut people off who try to use this time for their talks!
Please bring a copy of your talk on CD or USB stick to give to Presentation Support, Sunday morning at Registration.

Paper Submission
We invite all keynote speakers to submit a paper (either original research report, original review*or original tutorial*) to the European Cells & Materials (eCM) online 'Open & Free Access' journal.*NOTE: We define a REVIEW PAPER as a paper which includes an extended literature review and complete bibliography (including authors' own work), and can also emphasise authors' new unpublished findings and in an extended discussion puts the topic in proper perspective. A review can also be based on a complete bibliography of an author's own work over several years in relation to others. A TUTORIAL PAPER contains an organised comprehensive review of all relevant published material as for a teaching lecture.
