Transplanted olfactory ensheathing cells reduce the gliotic injury response of Müller cells in a rat model of retinitis pigmentosa

► Olfactory ensheathing cells potentially promote neuronal regeneration. ► Olfactory ensheathing cells inhibit over-activation of Müller cells. ► Olfactory ensheathing cells help to maintain the proper arrangement of glial cell. ► Olfactory ensheathing cells transplantation may be a new choice for retinitis pigmentosa treatment.
