ABSTRACT
Liver is one of the most important organs in the human body. Liver diseases are also a major threat to human health and longevity. Hepatic decompensation treatment is quite difficult due to multiple reasons. Extracorporeal liver support devices are unable to solve this problem, and there is a severe shortage of orthotopic liver transplant donors. Study of pluripotent stem cell-derived hepatocytes and organoids can determine not only hepatocyte fate, but also liver development, regeneration mechanisms, and pathophysiology. Furthermore, it can be used for drug screening in order to provide a stable source of functional hepatocytes for future transplantation therapy. Culture of pluripotent stem cell-derived hepatocytes and organoids has a self-organizing process similar to liver development, i.e., starting with changes in several key factors, and eventually forming functionally complex cells/organs. This paper introduces the main methods and progress of pluripotent stem cell-derived hepatocytes and organoids, with hope to provide clues for future research.

Bisphosphonates can directly inhibit osteoclasts, which may lead to increased bone density, reduced blood flow, and osteonecrosis of the jaw. Bisphosphonate-related osteonecrosis is usually observed in the jaw bone. In this article, we report a patient with bisphosphonate-related osteonecrosis of the jaw (BRONJ) complicated with wrist scaphoid osteomyelitis. Furthermore, we introduce the pathogenesis, treatment, and prevention of BRONJ.
