Mapping the Neurons of the Rat Heart in 3D

An interdisciplinary team of researchers, including MBF Bioscience’s Dr. Susan Tappan and Maci Heal, have created a fully reconstructed, virtual 3D heart, digitally showcasing the heart’s unique network of neurons for the first time. The investigators in this study–appearing May 26 in the journal iScience–created a comprehensive map of the intrinsic cardiac nervous system at a cellular scale using MBF Bioscience’s Tissue Mapper and TissueMaker software. This map also allows for gene expression data to be superimposed within it, which can help determine the functional role that specific neuron clusters play. The researchers say this map will allow neurologists and cardiologists alike to more precisely study the neuroanatomy of the heart and lays the groundwork for developing virtual maps for other major organs.
