A cell line, HuH-33 was cultured in vitro from a patient with hepatocellular carcinoma. This cell line has been in continuous culture over 12 month period with slow growth potential. HuH-33 was composed spindle-or polygonal-shaped cells as a major population. Chromosome number of the cells were widely distributed even in the primary culture. HuH-33 was transplantable into nude mice and secreted alpha-fetoprotein, albumin, beta 2 microglobulin, ferritin and tissue polypeptide antigen.

Myelin ensheathment and drug responses of oligodendrocytes are modulated by stiffness of artificial axons.

Myelination is a key biological process wherein glial cells such as oligodendrocytes wrap myelin around neuronal axons, forming an insulative sheath that accelerates signal propagation down the axon. A major obstacle to understanding myelination is the challenge of visualizing and reproducibly quantifying this inherently three-dimensional process in vitro. To this end, we previously developed artificial axons (AAs), a biocompatible platform consisting of 3D-printed hydrogel-based axon mimics designed to more closely recapitulate the micrometer-scale diameter and sub-kilopascal mechanical stiffness of biological axons.

Oxygen controls most metazoan metabolism, yet in mammals, tissue O levels vary widely. While extensive research has explored cellular responses to hypoxia, understanding how cells respond to physiologically high O levels remains uncertain. To address this problem, we investigated respiratory epithelia as their contact with air exposes them to some of the highest O levels in the body.

Immunologic bile duct destruction is a pathogenic condition associated with vanishing bile duct syndrome (VBDS) after liver transplantation and hematopoietic stem-cell transplantation. As the bile acid receptor sphingosine 1-phosphate receptor 2 (S1PR2) plays a critical role in recruitment of bone marrow-derived monocytes/macrophages to sites of cholestatic liver injury, S1PR2 expression was examined using cultured macrophages and patient tissues. Bile canaliculi destruction precedes intrahepatic ductopenia; therefore, we focused on hepatocyte S1PR2 and the downstream RhoA/Rho kinase 1 (ROCK1) signaling pathway and bile canaliculi alterations using three-dimensional hepatocyte culture models that form obvious bile canaliculus-like networks.

SOX9 is a crucial transcriptional regulator of cartilage development and homeostasis. Dysregulation of is associated with a wide spectrum of skeletal disorders, including campomelic dysplasia, acampomelic campomelic dysplasia, and scoliosis. Yet how variants contribute to the spectrum of axial skeletal disorders is not well understood.

Purpose: A human model able to simulate the manifestation of corneal endothelium decompensation could be advantageous for wound healing and future cell therapy assessment. The study aimed to establish an ex vivo human cornea endothelium wound model where endothelium function can be evaluated by measuring corneal thickness changes.
Methods: The human cornea was maintained in an artificial anterior chamber, with a continuous culture medium infusion system designed to sustain corneal endothelium and epithelium simultaneously.
