abstract = {Signal propagation in cardiac cell networks can be
modulated by heat stimulation. Here, we investigate the
response of a connected HL-1 cardiomyocyte cell network to
the application of confined heat stimuli using Ca2+ imaging.
Localized temperature gradients are generated by resistive
heating via microwire arrays on a chip surface, which serves
as a substrate for growing a confluent cell network. We
demonstrate that upon heat stimulation, the velocity of the
propagating Ca2+ wave in the network is locally increased,
leading to a deformation of the wavefront. Furthermore, we
show evidence of a change in the signal propagation
direction caused by a relocation of the pacemaker cell. This
effect might be used in future applications, where heat is
employed as an alternative modality for cell stimulation
protocols.},
