Regenerating photoreceptors in retinitis pigmentosa mice

/ Tuesday, 11 October 2016 / Published in NEWS

Retinitis pigmentosa covers a group of rare genetic disorders that cause retinal degeneration due to a loss of photoreceptors, the specialized cell-sensitive neurons that enable eyesight. By transplanting Wnt-activated hematopoietic stem and progenitor cells (HSPCs) we demonstrated that Muller cells can be reprogrammed in vivo after fusion with HSPCs. The newly generated hybrids can differentiate in photoreceptors leading to partial retina regeneration and to a certain degree of functional rescue. Sanges D, Simonte G DiVicino U, Romo N, Pinilla I, Nicolás Farrés M and Cosma MP (2016). In vivo conversion of Müller glia into photoreceptors through cell fusion-mediated reprogramming. Journal of Clinical Investigation, Aug 1;126(8):3104-3116
