Angiogenin-blockade suppressed MSCs-stimulated ovarian angiogenesis. a Representative figures showing microvascular density of ovarian tissues in shRNA blockage analysis, as determined by CD31 immunoactivity, at post-transplantation day-7 in each group. b Quantitative analysis of microvascular densities between different groups in shRNA blockage analysis, c Representative figures showing microvascular density of ovarian tissues in antibody blockage experiment, as determined by CD31 immunoactivity, at post-transplantation day-7 in each groups. d Quantitative analysis of microvascular density between different groups in antibody blockage experiment. Data shown are means ± SEM of triplicates in a representative experiment. MSC, mesenchymal stem cells; ANG, angiogenin; CTRL, control; Ab, antibody; shANG, ANG specific short hairpin RNA; shCTRL, control short hairpin RNA, * P < 0.05. Scale bar = 100 μm
