  • Moving Encounters: Actin Treadmilling in the Brush Border. [Journal Article]
    Dev Cell 2019; 50(5):529-530Kachar B
  • In this issue of Developmental Cell, Meenderink et al. (2019) describe how treadmilling of the actin core of nascent microvilli on the apical surface of epithelial cells underlies their motility across the cell surface, collision with each other, and ultimately clustering to form the "brush border."
  • Cytopathology and ultrastructure identification of primary hepatic acinar cell carcinoma: Case report. [Journal Article]
    Int J Surg Case Rep 2019; 62:120-125Grab JG, Skubleny D, Kneteman NM
  • CONCLUSIONS: This case showcased the novel utility of electron microscopy that was crucial in yielding the definitive diagnosis. The previous literature on hepatic ACC was compiled here in context of the present case. The mechanism of hepatic acinar cell localization was also discussed.Primary hepatic ACC may easily be confused for other lesions due to nonspecific imaging patterns. Specifically, the presence of a central scar without risk factors for HCC can favour a diagnosis of benign entities such as focal nodular hyperplasia (FNH). Electron microscopy presents an important tool to identify primary hepatic ACC and may improve future patient outcomes.
