Figure Lengend Snippet: Overexpression of ngn2 protects endogenous and transplanted RGCs in vivo. A AAV2-ngn2-EGFP or AAV2-EGFP particles were intravitreally injected 2 weeks into adult mouse eyes 2 weeks before optic nerve crush. Retina explants were harvested and immunostained 2 weeks after the optic nerve crush. Surviving RGCs were labeled with RBPMS (red). B A significantly greater RBPMS + RGC number was found on retina explants from the AAV-ngn2 treated group. C The EGFP and mCherry were used to label the entire transplanted and ngn2-overexpressing donor mouse RGCs, respectively. Ngn2-mCherry-overexpressing mouse RGCs that were transplanted into adult rat eyes shows significantly higher survival rates, compared with the negative control RGC transplant 1 week after transplantation in vivo. D & E Difference between transplanted RGC survival rates and average neurite lengths with and without ngn2 overespression was quantified . Donor RGCs overexpressing ngn2-mCherry grew significantly longer neurites than those from negative control-RGC transplantation in vivo. * P < 0.05, paired t-test.

Article Snippet: The flat mounted samples were permeabilized with 0.3% Triton X-100 (Cat. #T9284; Sigma-Aldrich) for 20 min, blocked with 5% normal goat serum (Cat. #16,210,064; Invitrogen, San Diego, CA, USA) in PBS for 1 h. For the retinas from optic nerve crush, the samples were incubated with a rabbit polyclonal anti-RNA Binding Protein, mRNA Processing Factor (RBPMS) antibody (1:500; Cat. #1832-RBPMS; PhosphoSolutions, Aurora, CO, USA) overnight at 4 °C, rinsed three times with PBS, and then incubated with Alexa Fluor 555-tagged secondary antibody (1:500; Cat. #A-21428; Life Technologies) overnight, again.
