Repeated intra-articular administration of equine allogeneic peripheral blood-derived mesenchymal stem cells does not induce a cellular and humoral immune response in horses.
Abstract: The use of mesenchymal stem cells (MSCs) for the treatment of equine joint disease is widely investigated because of their regenerative and immunomodulatory potential. Allogeneic MSCs provide a promising alternative to autologous MSCs, since the former are immediately available and enable a thorough donor screening. However, questions have been raised concerning the immunogenic potential of allogeneic MSCs, especially after repeated administration. Methods: Current retrospective study assessed the cellular and humoral immunogenicity of ten jumping and dressage horses with naturally occurring degenerative joint disease which were treated 3 times intra-articularly with a 1 mL stem cell suspension containing 1.4-2.5 million chondrogenic induced equine allogeneic peripheral blood-derived MSCs (ciMSCs) combined with 1 mL equine allogeneic plasma. Stem cells from 2 donor horses were used. Horses were clinically evaluated for joint effusion, presence of pain to palpation and skin surface temperature at the local injection site, joint range of motion, occurrence of adverse events and the presence of ectopic tissue. The cellular immune response was analyzed using a modified mixed lymphocyte reaction and the humoral immune response was investigated using a flow cytometric crossmatch assay by which the presence of alloantibodies against the ciMSCs was evaluated. Presence of anti-bovine serum albumin antibodies was detected via ELISA. Results: Clinical evaluation of the horses revealed no serious adverse effects or suspected adverse drug reactions and no ectopic tissue formation at the local injection site or in other areas of the body. Generally, repeated administration led to a decrease of horses with joint effusion of the affected joint. Pain to palpation, skin surface temperature and joint range of motion did not increase or even decreased after treatment administration. Allogeneic ciMSCs did not induce a cellular immune response and no alloantibodies were detected in the recipients' serum, regardless the presence of BSA antibodies in 70 % of the horses. Conclusions: Repeated intra-articular injections with allogeneic equine ciMSCs did not elicit clinically relevant adverse events. Furthermore, current study indicates the absence of a cellular or a humoral immune response following repeated intra-articular injections.

This research paper looked at whether the repeated use of allogeneic mesenchymal stem cells (MSCs) for the treatment of joint disease in horses provoked an immune response, and concluded that it did not.
Research Goals
The goal of this research was to investigate whether allogeneic, or non-self, mesenchymal stem cells (MSCs) provoke an immune response in horses that receive repeated intra-articular injections of the cells.
Reasons for Study
MSCs are potentially a very potent tool for treating joint disease in horses. However, questions have been raised concerning whether or not MSCs might provoke an immune response in horses, especially following repeated administrations into the joints.
Methods
The researchers worked with ten horses who were experiencing degenerative joint disease. Each horse received three intra-articular injections of a stem cell suspension that was made up of chondrogenic induced equine allogeneic peripheral blood-derived MSCs (ciMSCs) combined with equine allogeneic plasma.
The researchers then evaluated the horses for various clinical signs such as effusion in the joints, pain upon palpation, skin surface temperature at the injection site, joint range of motion, adverse events, and the presence of any ectopic tissue.
The immune response was assessed by testing for the presence of alloantibodies against the ciMSCs in the recipient’s serum, and detecting anti-bovine serum albumin antibodies.
Results
The results showed that the repeated administration of allogeneic ciMSCs did not induce a cellular immune response nor cause the formation of alloantibodies in the horses’ serum.
Clinically, the horses did not experience adverse effects or suspected adverse drug reactions, and no ectopic tissue formation was observed.
Generally, repeated administration improved the condition of the joints, pain and palpation.
Conclusions
In conclusion, the study found that repeating intra-articular injections with allogeneic equine ciMSCs did not elicit adverse events or provoke a cellular or humoral immune response in horses.
