Murine blood was drawn from retro-orbital plexus of the eyes, and bone marrow was collected from femur and tibia bones. BNs and BMNs were isolated using Histopaque-1119 and Histopaque-1077 (Sigma-Aldrich) according to the manufacturer’s instructions. The purity of BNs and BMNs populations was greater than 90% as determined by flow cytometry after staining with anti-Ly6G-APC (eBioscience), and the viability was greater than 99% as determined by trypan blue staining.
