In Rspondin-based 3D cultures, Lgr5 stem cells from multiple organs form ever-expanding epithelial organoids that retain their tissue identity. We report the establishment of tumor organoid cultures from 20 consecutive colorectal carcinoma (CRC) patients. For most, organoids were also generated from adjacent normal tissue.

Purpose: Transient receptor potential subfamily melastatin (TRPM)1 cation channels of retinal ON-bipolar cells are modulated via a mGluR6 (GMR6) signaling cascade. While light-microscopy shows these channels are located on the tips of ON-bipolar cells dendrites, near rod and cone synaptic ribbons, TRPM1 localization at the electron-microscope level is currently not described. The authors report here the ultrastructural localization of TRPM1 in the human retina.
