"Forces in tissues" workshop

May 19-23, 2014, Université Paris 7 Diderot


This is an informal workshop open to anyone who is actively performing, or who has performed, force or stress measurements in situ in living tissues.

Please note that participants are responsible for finding their own accommodation in Paris, and that we are unable to guarantee any funding.

Scroll down for the registration form (deadline February 28th, 2014), and for details of how to get there.

To facilitate discussions during the workshop, we would like you to submit an A4 2 page-document by May 12th (please see details below).

We start at 9:30 the first day.

We change slots of some methods. Please check the program below.


Understanding the interplay between genetics and mechanics in living tissues, especially during morphogenesis, is an active field of research. After years of emphasis on description of tissue deformation, cell-level dynamics, and molecular activities, the community currently devotes a large effort to measuring forces and stresses in situ. Several methods have recently been published, others are in preparation. This workshop aims at encouraging:

- discussions between researchers in the field

- exchange of published and unpublished information

- discussion of respective advantages and drawbacks of each method for any given tissue/organism

- mutual validations of independent methods

- link between different scales: molecule, cell, tissue

- improvement of existing methods

- development of new methods

- new collaborations

Structure of the workshop

The workshop is purposedly informal:

- free registration (and no support for finding money or lodging)

- discussions and chalk-talks, rather than video-projections and invited speakers

At each discussion, participants will design a time-keeper and a secretary to take notes.


Discussions will be held approximately from 9h to 12h and from 14h30 to 17h30, with breaks (on monday, we start at 9h30). The exact program will be adapted according to the participants presence. Some time will be devoted to general discussions. Each method and its variants will be specifically discussed during one morning or afternoon.

The workshop is opened to anybody, from beginners to advanced users, who has been or is actively performing force or stress measurements in situ in living tissues, or modelling involved in corresponding methods.

To favor discussions, the number of participants is strictly limited. Registration, although free, is thus mandatory: scroll down for the registration form.

The selection of participants aims at balancing the different measurement methods, and also the fields of research.

A few seats might be kept for researchers in related fields such as:

- in vitro measurements of force and stress

- in vivo measurement of elastic and viscous moduli

Dates and places

It will take place on May 19 to 23, 2014 in Univ. Paris 7 “Denis Diderot”, Paris Rive Gauche campus, Condorcet A building, 3rd floor. We meet in room 366A-Klimt. (Note : A smaller room is available for parallel discussions or private work)

Please read carefully the following explanations and print the maps.

The “Paris Rive Gauche” campus of University Paris 7 "Denis Diderot" is in the south-east of Paris (XIIIth district), between the National Library and the ringroad. It can be accessed from the station “Bibliothèque François-Mitterrand” of RER C or subway line 14, by buses 89, 62, 64, 325, and by the “velib” bicycles.

The Condorcet building is close to the Seine river and has a distinct orange color. From subway line 14, RER C or bus 89 (arrêt “Bibliothèque François Mitterrand”) go to the Seine by walking downhill, then turn right. See the map of the district (move your mouse to see the Condorcet building on the bottom left) and the detailed map of the building. On these maps, green dots label the building entrances.

Caution: these streets are new. Some commercial maps or GPS systems have not yet incorporated them. Watt street, which is almost identical to Alice Domon and Léonie Duquet, is normally always indicated.

Caution again: this building is subdivided into two subunits, Condorcet A and Condorcet B, which are connected only at the ground floor (as well as a footbridge at 4th floor and another one at 6th floor).

Caution again: at night it is only possible to leave this building through the guarded door on 10 rue Alice Domon and Léonie Duquet, close to the river.

Practical details

Participants are responsible for finding their own accommodation in Paris, or south-east suburb such as Ivry.

Wifi for academic participants: eduroam is available at the venue, but you must register at your home institution in advance; if you need an alternative wifi, please let us know on the registration form.

Visa : Persons who need an acceptance letter for visa should contact us quickly.

Food : The food from monday, May 19th to thursday, May 22nd will be at University Restaurant Buffon. There will be a self-service starter buffet followed by a main dish: Monday : lamb, Tuesday : salmon, Wednesday : duck, Thursday : shrimps This will be paid by the workshop. If you want a modification of this menu (eg for dietary, allergy or personal reasons, including vegetarians), please notify us before may 5th at latest. If you don't want to eat there, you can go to nearby restaurants or bring your own food. In that case, please notify us before may 5th at latest. For Friday, May 23rd, we will organise a buffet to eat together in the lab. If you can bring something to eat, to share with others, it would be nice (for instance a specialty from your home town).

Coffee breaks : Coffee will be provided by the workshop : 3 coffees per person and per day. If you can bring biscuits or cakes, to share with others, it would be nice.

Organisers will apply for a limited funding if one or two participants need support.
