“…Histopathological findings revealed marked bile duct proliferation and fibrosis ( Figure 1 A). These findings are also observed in BDL hen livers in our previous reports ( Nagasao et al, 2021 ). The myofibers from PCT and FTL in the SHAM group, were polygonal with multiple subsarcolemmal nuclei, and were similar in morphology to all skeletal muscle types.…”

“…In our previous work, we focused on the atrophy of different muscle fiber types following BDL in chickens. We concluded that hepatic fibrosis, as a result of BDL surgery induced skeletal muscle atrophy in PCT type II fibers ( Nagasao et al, 2021 ). In FTL, type I fibers became hypertrophic, but atrophy was observed in type II fibers ( Nagasao et al, 2021 ).…”

Myopenia (reduced skeletal muscle [SM]) is common in children with end-stage liver disease (ESLD) with suboptimal nutritional status pre-and post-liver transplantation (LTx). Myopenia may result in altered SM morphology (changes in muscle fibre size and types [type I vs. II proportions]) contributing to adverse outcomes and deficits in muscle strength/functionality. Understanding SM morphology changes in healthy children with age, and the potential impact of ESLD on SM morphology offers insight into the effectiveness of rehabilitation strategies for children with ESLD at risk for myopenia. Literature searches in PUBMED, SCOPUS, and WEB OF SCIENCE identified studies examining SM morphology in healthy children, and in ESLD. Muscle fibre size increases with age in healthy children. Type I fibres are more prevalent in childhood, whereas type II fibres increase post-puberty. Preliminary evidence indicates that adults with ESLD have reduced muscle fiber size with type II fibre atrophy. No data is available in pediatric ESLD. SM morphology changes with age and may be impacted by the negative physical and metabolic insults associated with ESLD and malnutrition.
