Changes in testicular vascularization following injury. a Numbers of vessels per field of view compared with sections from unaltered control animals. Dark gray bars, 1 month follow-up; bright gray, 3 months; dotted line, unaltered control animals, n = 2. The results are presented as medians with 25th and 75th percentiles; three sections were analyzed per testicle. Intergroup differences were not significant. Three animals were analyzed for each mean in untreated and MSC groups, and four animals in vehicle and MSC secretome groups. b Representative microphotograph of blood vessels on a tissue section; blue pseudocolour, DAPI; green, VE-cadherin; scale bar = 50 μm
