    This study shows in vivo and in vitro evidence to support a novel tree shrew model of lung fibrosis. Tree shrews are genetically, anatomically, and metabolically closer to humans than rodents or dogs; therefore, the tree shrew model presents a unique opportunity for basic and translational research in lung fibrosis.

    Polarization-second harmonic microscopy was utilized to investigate whether collagen ultrastructure in thyroid due to four carcinoma types and Graves’ disease could be differentiated in human histopathology samples. Three parameters were extracted, revealing that the degree of linear polarization and χ(2)zzz/χ(2)zxx were effective in differentiating some diseases, while the parameter χ(2)xyz/χ(2)zxx was less effective.

    This study demonstrates that small clusters (sCLs) of tumor cells with high expression of LGR5 continuously form in the invasive front in a colorectal cancer xenograft model. This structure is characterized by stress response and partial/hybrid epithelial-mesenchymal transition. These sCLs are an important contributor to tumor growth and the expansion of cancer stem cells.

    Overexpression of pigment epithelium-derived factor (PEDF) in placenta-derived mesenchymal stem cells (PD-MSCs) improved the mitochondrial activities, and induced regeneration of oxidative stress-damaged RPE through regulating oxidative status and mitochondrial biogenesis. Therefore, genetic modification of PD-MSCs with PEDF might be a new cell therapy for treatment of retinal degenerative diseases.

    Combination of antihypertensive drugs with NSAID analgesics may cause a syndrome called triple whammy (TW) acute kidney injury (AKI), most often in the elderly. A rat model reveals that the TW-AKI is a prerenal form of AKI, only occurring in previously dehydrated rats, a condition particularly rife among the aged.

    In this study, the authors assess the early pathogenesis of cystic fibrosis (CF) pig gallbladder disease. The CF pig gallbladder epithelium lacks cAMP-stimulated anion and fluid transport. CF pig gallbladders also demonstrate increased luminal mucins MUC5AC and MUC5B accumulation without significant changes in the epithelial expression of gel-forming mucins compared to non-CF pigs.
