Mean and SEM of histomorphometric indices of seminiferous tubules in busulfan-induced azoospermic testis treated with bone marrow-derived mesenchymal stem cells (cell therapy) in comparison with busulfan treated testes (azoospermia) and intact testis (normal) in rat. A, Lumen diameter (μm), B, Luminal area (μm²), C, Cellular diameter (μm), D, Cellular area (μm²), E, Total diameters (μm), F, Cross sectional area of the tubules (μm²). ^{a, b, c} different superscript letters show significant differences between groups (P<0.05)
