Abstract

The invention discloses a stem cell preparation for treating canine arthritis and a preparation method thereof. The stem cell preparation comprises canine mesenchymal stem cells, canine serum albumin, hyaluronic acid and pharmaceutical salts. Injections of the mesenchymal stem cells are skillfully used, a knee joint cavity is positioned through B-mode ultrasound, the cells are injected into the knee joint cavity of an affected limb more accurately, and a traditional treatment method for the canine arthritis is broken. The stem cell preparation is high in stability, good in therapeutic effect, safe in using, suitable for being preserved and transported for a long time and free of toxic and side effects, and lays the foundation for being used clinically on a large scale.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to a stem cell preparation for treating canine arthritis and a preparation method thereof. Background technique [0002] Nowadays, with the increase of companion animal dogs year by year, canine OA is also increasingly valued by humans. OA causes swelling, pain, deformation, and effusion in the dog's joints, which leads to a series of obstacles affecting motor function. According to the etiology of OA, it can be divided into primary and secondary OA. Elderly dogs often suffer from primary OA due to excessive exercise and bone aging. Secondary OA can be caused by trauma, wear and other reasons that affect the normal function of the joints. The complex reality limits the treatment options for OA. At present, there is no drug or non-surgical treatment that has a clear effect on reversing or stopping the progression of the disease, and there is no therapy that can control the p...
