(A) The morphology of organelles in matured ciPTEC cultured on HFM (H) was investigated by transmission electron microscopy and intact cells were detected. Next to numerous well-developed mitochondria, the nucleus (N) containing the chromatin (Ch), the endoplasmatic reticulum (E), ribosomes (R) and the Golgi apparatus could be nicely detected. (B) The surface of matured ciPTEC was visualized using scanning electron microscopy. At the apical membrane microvilli were observed, as expected for proximal tubule epithelial cells, though a heterogeneous distribution was detected.
