Fig. 3From: Assessment of effectiveness and safety of repeat administration of proinflammatory primed allogeneic mesenchymal stem cells in an equine model of chemically induced osteoarthritisRepresentative images of the radiology, ultrasonography and magnetic resonance imaging (MRI) assessments, taken from one animal from each group (control, MSC-naïve and MSC-primed). a Radiologic images (frontal views) are presented for two (score 3) and six months (score 3–4) of progression. Score 6 is the highest possible. Joint space narrowing and marginal bone remodeling (white arrows) were progressively observed; note that the radiologic evolution was similar between the three groups. b Ultrasound images are presented for Week 2 (first injection) and Week 3. Note that synovial effusion (dashed line) was faster reduced in both MSC-naïve and MSC-primed groups than in control. c Magnetic resonance images (T2* gradient echo [GE], sagittal planes) are presented for showing the different synovial effusion (black arrows) found between groups at two months (scores 1, 0 and 3 were assigned to the images showed for control, MSC-naïve and MSC-primed groups, respectively)Back to article page
