NRP2⁺ RECs have a higher proliferation capacity than NRP2⁻ RECs. a Proliferation rates of NRP2⁻ and NRP2⁺ RECs at passage 3 (n = 11 or 9 per group). A total of 1 × 10⁵ cells were seeded on 10-cm culture dishes, and the number of cells was counted after 5 days. b Correlation between the proliferation rate and expression level of NRP2. c Growth potential of representative NRP2⁺ and NRP2⁻ RECs from passages 4–10.
