SUMMARY:Sascha Ollertz\, "Agent-based modelling of cell differentiation patterns in mouse blastocysts"
DESCRIPTION:Early embryonic development from zygote to blastocyst is a highly dynamic\, self-organised process in which stem cells undergo successive cell fate decisions and form a complex structure. Local patterns in the early and mid blastocyst stage resolve into global patterns in the late stage of the blastocyst . A first modelling approach\, based on cell division and signalling showed that the spatial cell fate patterns arising in the earlyand mid stage\, are compatible with signalling beyond the nearest neighbours . As a next step\, we expanded our existing mathematical\, agent-based model to incorporate the late stage by including cell sorting based on differential adhesion. The resulting model consists of cell division\, cell death\, physical interactions\, transcription and signalling between the cells. The model allows us to systematically investigate the influence of these mechanisms and their relative timing with respect to the formation of the global pattern in the late blastocyst stage.\n Fischer\, S.
