Figure 6: Transversal (T) and longitudinal (L) ultrasound images of a lesion (white circle) in accessory ligament of the deep digital flexor tendon (ALDDFT) in 3 horses (H) before (left column) and 6 weeks after (right column) treatment with tenogenic induced allogenic mesenchymal stem cells (Tendo-Cell® =TC). At approximately 6 weeks after the treatment, a score 4 was given to all the treated ALDDFTs, because although the fiber orientation was completed, there were still some small hypo-echoic zones.
