Regulation of Hepatic Differentiation of Human Embryonic Stem Cells by Calcium Silicate Extracts for Liver Injury Repairing

The roles of calcium silicate (CS)-activated H9 cells in liver injury repair were tested by cell tracking and immunohistochemical staining. Results indicated that high concentrations of CS extracts initially enhanced definitive endodermal (DE) lineage, followed by gradual DE differentiation at low CS concentrations.

An Endoplasmic Reticulum Stress‐MicroRNA‐26a Feedback Circuit in Nonalcoholic Fatty Liver Disease

Scientists identified a negative feedback loop comprising hepatic endoplasmic reticulum (ER) stress and micro RNA (miRNA)‐26a in nonalcoholic fatty liver disease pathogenesis. Combining miRNA dot blot array and quantitative PCR, they found that miR‐26a was specifically induced by ER stress in liver cells.
