Liver specification of human iPSC-derived endothelial cells transplanted into mouse liver.

Background & Aims: Liver sinusoidal endothelial cells (LSECs) are important in liver development, regeneration, and pathophysiology, but the differentiation process underlying their tissue-specific phenotype is poorly understood and difficult to study because primary human cells are scarce. The aim of this study was to use human induced pluripotent stem cell (hiPSC)-derived LSEC-like cells to investigate the differentiation process of LSECs.

Methods: hiPSC-derived endothelial cells (iECs) were transplanted into the livers of // mice and assessed over a 12-week period.

Endoscopic management of ingested toothpick resulting in duodeno-ureteric fistula.

Toothpicks are commonly used but rarely ingested. Unlike most foreign bodies, if accidentally swallowed these rarely spontaneously pass. The duodenum has been reported as the most common site of toothpick foreign body lodgement in the upper gastrointestinal tract.

Recurrence and outcomes of non-functional pancreatic neuroendocrine tumours post-resection: an Australian retrospective, multicentre cohort study.

Introduction: Pancreatic neuroendocrine tumours (PNETs) are heterogenous entities with variable clinical outlook. The prevalence of PNETs is increasing in Australia. Despite this, data on peri-operative management and post-operative prognosis for Australian patients is scant in the literature.
