Experimental study on cultivation of adult human retinal neural cells / 眼科

ABSTRACT

Objective To establish a culture system in vitro of adult human retinal neural cells for providing a model for the research of retinal neural cells. Design Experimental study. Participants Cultured adult human retinal neural cells. Methods The isolated cells from adult human postmortem retina (20?40 years old) were cultured, then cells of different stages were identified with immunocytochemical staining and judged with phase contrast microscopy and electron microscopy. Main Outcome Measures Cellular morphology and structure. Results (1) The results of cell culture the adult retinal neural cells could survive in vitro under some conditions and were identified as NSE positive mostly. (2) The results of electron microscopy most cultured cells were photoreceptors, bipolar cells, horizontal cells and some were glial cells with scanning electron microscopy. Conclusions Under feasible conditions, the adult human retinal neural cells could be cultured and maintained effectively in vitro.
