Recovery of Fertility in Azoospermia Rats after Injection of Adipose-Tissue-Derived Mesenchymal Stem Cells: The Sperm Generation

Figure 7

GFP⁺ cells in seminiferous tubule. MSC-received testis was fixed and stained for GFP (green) and spermatogenic cell marker, VASA (red). The cells in seminiferous tubule with dual staining were shown by arrows (a4). The adjacent tubules showed no staining for VASA, which indicated the absence of spermatogenic activity.
