(Submitter supplied) The adult mammalian heart is incapable of regeneration following injury. In contrast, the neonatal mouse heart has a transient ability to regenerate, however the molecular mechanism that mediates this regenerative response is not fully understood. Here, by single-nucleus RNA sequencing we map the transcriptome landscape of cardiomyocytes in neonatal mouse hearts at healthy, regenerative, and remodeling conditions. more...

(Submitter supplied) The adult mammalian heart is incapable of regeneration following injury. In contrast, the neonatal mouse heart can efficiently regenerate during the first week of life. The molecular mechanisms that mediate the regenerative response and its blockade in later life are not understood. Here, by single-nucleus RNA sequencing, we map the dynamic transcriptional landscape of five distinct cardiomyocyte populations in healthy, injured and regenerating mouse hearts. more...

(Submitter supplied) Background - The inability of the adult mammalian heart to regenerate following injury represents a major barrier in cardiovascular medicine. In contrast, the neonatal mammalian heart retains a transient capacity for regeneration, which is lost shortly after birth. Defining the molecular mechanisms that govern regenerative capacity in the neonatal period remains a central goal in cardiac biology. Here, we construct a transcriptional atlas of multiple cardiac cell populations, which enables comparative analyses of the regenerative (neonatal) versus non-regenerative (adult) state for the first time. more...

(Submitter supplied) The adult mammalian heart has limited capacity for regeneration following injury, whereas the neonatal heart can readily regenerate within a short period after birth. Neonatal heart regeneration is orchestrated by multiple cell types intrinsic to the heart, as well as immune cells that infiltrate the heart after injury. To elucidate the transcriptional responses of the different cellular components of the mouse heart following injury, we performed single cell RNA-sequencing on neonatal hearts at various time points following myocardial infarction, and coupled the results with bulk tissue RNA-sequencing data collected at the same time points. more...

(Submitter supplied) Cardiomyocytes are highly metabolic cells responsible for generating the contractile force that drives heart function. During fetal development and regeneration, these cells undergo active division but lose their proliferation activity in the adult heart. The mechanisms that coordinate their metabolism and proliferation are not fully understood. Here, we study the developmental functions of the transcription factor NFYa, which we previously identified from regenerating cardiomyocytes. more...

(Submitter supplied) Rationale: Neonatal mice have the capacity to regenerate their hearts in response to injury, but this potential is lost after the first week of life. The transcriptional changes that underpin mammalian cardiac regeneration have not been fully characterized at the molecular level. Objective: The objectives of our study were to determine if myocytes revert the transcriptional phenotype to a less differentiated state during regeneration and to systematically interrogate the transcriptional data to identify and validate potential regulators of this process. more...

(Submitter supplied) As Grl/Hey2 directly binds DNA through E box motifs and mediates transcription repression, we aim to gain insights into potential target genes of Grl/Hey2 during heart regeneration. We performed RNA-seq analyses using total RNAs collected from 4-HT-treated Tg(cmlc2:creER;cmlc2:nRSGG) hearts and Tg(cmlc2:nRSGG) control hearts, as well as grl5nt-/- mutant hearts and wild-type hearts following ventricular resection at 7 dpa. more...
