Cell-to-Macroscale Working Group

Mission: Discuss and share numerical methods, models, and experiments that facilitate integration of subcellular and cellular scales with the macroscopic scales in the human body and other biological contexts, e.g., imaging and geometric modeling, transport within biological fluid flows, tissue properties and tissue mechanics, and uncertainty quantification.

* italicized and underlined text is a proposed modification to the mission statement for consideration at the 2017 WG session.

 

Working Group Leads:

Ed Sander (edward-sander@uiowa.edu)

Ross Carlson (rossc@montana.edu)

 

 

Brief History:

This WG can be traced back to WG3 “Cardiovascular and Pulmonary – hemodynamics and fluid dynamics” (lead Rob Kunz) in 2006. In 2009 it was restructured by merging WG3 Macro-To-Micro Scale Imaging and Transport in Biological Systems and WG7 Multiscale Imaging (lead Yoonsuck Choe). At the 2010 MSM consortium meeting, the goals of WG3/7 were discussed and a white paper entitled "Cell Scale to Macroscale Integration" was presented. Four examples of multiscale model integration were discussed: airway defense system, cerebro-vasculature, gastrointestinal tract and tumor growth. One of the major goals discussed was about the publication of special issues on multiscale modeling in archival journals to document numerical methods and strategies for integration of models at various scales through a peer review process. The WG was renamed as the Cell-to-Macroscale WG after this consortium meeting.

 

Goals and Objectives:

  1. Promote IMAG and MSM missions.
  2. Organize WG activities leading to concrete outcomes: Publications, proposals, collaborations, recommendations to IMAG, etc.
  3. Facilitate communication among WG members.
  4. Identify issues (both research and policy) and act on them.

Summary of Discussion from the Breakout Session:

2:10-3:00pm, September 8, 2015

  1. Mission Statement
  • Read the mission statement and discussed expanding the WG focus from numerical methods to also include models and experiments.
  • Discussed what subcellular actually encompasses and how to define the range of scales of interest to the group.
  • Also should consider expanding the scope to extend beyond human health, and to consider biofilms and other areas of interest that fit the WG.
  • There was also a suggestion that we provide examples of what cell-to-macro scale is.

 

  1. Introduction
  • Each participant introduced himself or herself and summarized their research interests. It became apparent that certain topics had some density, such as wound healing, biofilms, mechanobiology, cell-matrix interactions, cancer, transport phenomena, relating in vitro data to animal models.
  • It was suggested that forming subgroups centered on keywords such as these might help foster actionable items for the WG.

 

  1. 2014-2015 achievements
  • Hosted two webinars: (1) Jie Liang, University of Illinois at Chicago and (2) Keith Gooch, Ohio State University.
  • Co-hosted a s Special Session on Multi-scale Modeling featuring MSM members from Biomechanics (primary) and Cell-to-Macroscale (secondary) Working Groups at the 12th International Symposium on Computer Methods in Biomechanics and Biomedical Engineering (CMBBE), Amsterdam, The Netherlands, October 13-15, 2014. http://www.cmbbe2014.com/

 

  1. Review of last years plans
  • Mentioned Predictive Model Index for new participants
  • Discussed ideas of trying to foster more interactions between WG members and with non-modelers and decided that might be best handled by subgroups with focused interests or via social media, e.g. ResearchGate.
  • Still need to conduct a survey of WG members

 

  1. 2015-2016 Proposed WG activities
  • Host at least two webinars with the idea of one in the Fall, one in the Spring, and two in the Summer.
  • Have a tentative commitment from John Dallon from BYU for the Spring
  • Welcome volunteers from the WG to present their research as well
  • Will conduct a series of brief surveys over the course of the year to better define the interests of the group in an attempt to create focused subgroups and to develop actionable items for next years meeting.

Summary of Discussion from the Cell-to-Macroscale Breakout Session:

1:00-2:30pm September 3, 2014

  1. History of Working Group (12:10 – 12:12)
  2. 2013-2014 Achievements
  3. Mission Goals and Objectives
  4. Who are we? We went around the room and briefly introduced ourselves, spoke about what our research interests are, and why we thought cell-to-macroscale was the right working group. We found a wide range of interests that all seemed to meet at the interface of the cell. Some of us are interested in the role of solid mechanics, fluid mechanics, while others are interested in biochemical signals and molecular pathways. Some are interested in tissue-level phenomena but need to incorporate some level of abstraction at lower scales that stops at the cell. Some are interested in subcellular phenomena, microtubule dynamics and the cytoskeleton and linking it to whole cell behavior.
  5. Went over recommendations from last time.
  6. General Discussion: Mentioned that there was a lack of nanoscale mechanics represented so we will make an effort to incorporate this into the Wiki and future discussion.
  7. Want to conduct a survey to find out more details about the working groups expertise and interest using a collection of key words.
  8. Predictive Model Index  - discussed what the index is and then larger community discussions that have been occurring over feelings about releasing code along with publications.
  9. Separation between biologists and modelers. How to attract more of the data collected by biologists to modelers, e.g. by creating more of an online community?
  10. Resolve to create a better sense of community maybe on Research Gate or some other online community that will foster more collaboration within the working group and bring traffic and communication from outside
  11. Explore setting up a session with a biologist conference to emphasize what multi-scale modeling can do for them. Possible candidates AJP, American Society of Cell Biology, Nature Editors – Frontiers Meeting

Suggestions from Jim Bassingthwaighte via emails dated September 4, 2014:

1. Model indexing: provide a brief description for each model listed, and put a paragraph at the top of the model list about the instructions for submission and review (any committe to review and approve submissions).

2. Develop a set of examples that utilize Uncertainty Quantification, e.g. by collecting a set of e.g. 20 papers on this topic and even putting them into a special issue of a journal or a WG-sponsored book.

 

(Tentative) Plans for 2014-2015:

  1. Incorporate nanoscale mechanics into the WG scope and future discussion.
  2. Conduct a WG survey to better position ourselves.
  3. Bridge biologists and modelers and foster more collaboration within WG members by creating an online community.
  4. Promote multi-scale modeling by setting up a session with a biologist conference.
