Key result
Pre-natal sheep ventricular architecture varies by age, featuring late-gestation purkinje fiber predominance.
Population
Collected foeti of non-descript sheep across three prenatal age groups
Comparison
Early prenatal (up to 50 days) vs mid prenatal (51-100 days) vs late prenatal (101 to 150 days)
Design
Scanning electron microscopic study

Provides initial ovine fetal heart ultrastructure; leaves open translational value for congenital anomalies in animals or humans.
Observational
Sahu et al. (2021) conducted an observational in Pre-natal non-descript sheep. Gestational age was evaluated on Ultrastructural details of ventricular architecture. The ultrastructural ventricular architecture of pre-natal sheep showed significant age-wise variations, with endothelial cells changing from oval to elongated and purkinje fibers becoming predominant in late gestation.
