Collection, processing, freezing of equine bone marrow cells

Using cell therapy is now a common practice in most equine clinics, mostly for musculoskeletal disorders such as tendonitis and laminitis. This therapy has also been shown to be useful when treating respiratory diseases. Because of their anti-inflammatory and microbicidal effects, bone marrow mononuclear cells (BMMCs) are extensively used. Other advantages are the lower risk of immunological reactions and the shorter processing time.
Depending on the species and diseases treated, the number of cells needed for treatment varies. However, in horses there are no studies showing the amount of cells that can be obtained from large bone marrow samples. There are also no conclusive studies about the ideal puncture location - sternum or ilium.

This study demonstrates the possibility to collect large amounts of equine bone marrow even in middle-aged and advanced-aged equines. It also shows that the heparin concentrations do not influence the isolation of BMMCs. Finally, it is shown that even though cryopreservation reduces cells viability, they stay feasible and useful in equine clinics.
