From: Long-term culture of cholangiocytes from liver fibro-granulomatous lesions
Phase-contrast microscopy of cells derived from dissociated acute phase granulomas. A. Homogeneous culture of liver connective tissue cells. B. Confluent stationary cultures presenting a monolayer of connective tissue cells and epithelial colonies (arrowheads). C. Patches of epithelioid morphology (arrowhead). D and E. Progressively differentiated epithelioid patches distinguished by light birefringence (arrows). F. Large epithelial patch with a network of small duct-like passages between cells (arrows). (750×).
