Here, we present the operating protocol for identifying immune cell substrates with this technology in lung cancer and paired brain metastasis samples. Neuroscience Organotypic Retinal Explant Cultures from Macaque Monkey Wenrong Xu1, Yujie Dong1, Yan Li1, Zhulin Hu1, François Paquet-Durand2, Kangwei Jiao1 1Yunnan Eye Institute & Key Laboratory of Yunnan Province, Yunnan Eye Disease Clinical Medical Center, Affiliated Hospital of Yunnan University, Yunnan University, 2Institute for Ophthalmic Research, Eberhard-Karls-Universität Tübingen Retinal explants obtained from wild-type macaques were cultured in vitro. Retinal degeneration and the cGMP-PKG signaling pathway was induced using the PDE6 inhibitor zaprinast. cGMP accumulation in the explants at different zaprinast concentrations was verified using immunofluorescence.
