Fig. 4From: A safety evaluation of allogeneic freeze-dried platelet-rich plasma or conditioned serum compared to autologous frozen products equivalents in equine healthy jointsEight horses were randomly assigned to the platelet-rich plasma (PRP) or conditioned serum (CS) groups (4 horses each group). All horses had the ipsilateral middle carpal, metacarpophalangeal, and tarsocrural joints injected with autologous frozen (AUTO) PRP or CS preparations. The contralateral joints were injected with allogeneic freeze-dried (FD-ALLO) preparation of the same product (i.e., PRP or CS). Horses were clinically evaluated and synovial fluid was collected before treatment (0Â h) and at 6, 24, 48, 96 and 168Â h after treatment injectionBack to article page
