Extrauterine support of pre-term lambs achieves similar transcriptomic profiling to late pre-term lamb brains.

ABSTRACT: Our group has developed an extra-uterine environment for newborn development (EXTEND) using an ovine model, that aims to mimic the womb to improve short and long-term health outcomes associated with prematurity. This study's objective was to determine the histologic and transcriptomic consequences of EXTEND on the brain. Histology and RNA-sequencing was conducted on brain tissue from three cohorts of lambs: control pre-term (106-107 days), control late pre-term (127 days), and EXTEND lambs who were born pre-term and supported on EXTEND until late pre-term age (125-128 days). Bioinformatic analysis determined differential gene expression among the three cohorts and across four different brain tissue sections: basal ganglia, cerebellum, hippocampus, and motor cortex. There were no clinically
