Subretinal microglia support donor photoreceptor survival in rd1 mice.
Purpose: To investigate the potential relationship between subretinal microglia and transplanted donor photoreceptors.
Methods: Photoreceptor precursors were transplanted into wild-type mice and rd1 mice by trans-scleral injection. Immunohistochemistry was employed to detect microglia and macrophages. PlX5622 feed was used to achieve microglia depletion and microglia repopulation. RNA-seq and qPCR were utilized to evaluate gene expression. Confocal microscopy was used to observe the interaction between microglia and donor photoreceptors.
Results: Donor photoreceptors survived in rd1 mice but not in wild-type mice after trans-scleral injection. The microglial cells closely interacted with donor cells. While donor cells failed to survive in rd1 mice after microglia depletion, they could survive following microglia repopulation. The RNA-seq analysis showed a pro-neurodevelopmental effect of sub-retinal microglia/RPE tissue in rd1 mice.
Conclusions: Subretinal microglia supported donor photoreceptor survival in rd1 mice.
