全國有數以千計患退化性關節炎的狗,接受了幹細胞治療,這種治療每次收費2500美元至3000美元,沒有獨立的研究證明幹細胞療法有效,但這些寵物的主人說,他們的寵物在屋內走動更容易,姿勢也有改善,整體看來更舒適… 邁阿密居民費希曼夫婦的寵物、五歲的拉布拉多與貴賓犬混種狗露西,因患風溼性關節炎後腿無法行走,只能用前腿在地上爬行,在接受了昂貴的三針靜脈注射幹細胞後,情況改進,不再因疼痛而嚎叫或嗚咽,需要的藥物也比以前少。儘管專家說,缺乏證據顯示這種治療有效,但視露西如女兒的費希曼夫婦認為幹細胞治療有效,他們認為露西能活到五歲也是這種療法的功勞,他們將再花3000美元,為露西打第四針。

為露西做幹細胞治療的是佛羅里達大學獸醫克莉絲汀‧柯克比,她說,其他五個類似的治療都有正面的效果,但這些效果都是根據主人的報告,不是科學的驗證,該大學計畫開始對每個寵物做治療前疼痛調查,和治療後的評估及檢查,以衡量其改變。一些專家也建議需要做類似的研究,來評估這種療法的療效。

加州的Vet-Stem公司在2003年研發幹細胞療法,該公司從全國的狗的脂肪樣本中擷取幹細胞,這個療法主要是治療關節中軟骨流失的骨關節炎,幹細胞療法能使動物更換軟骨或其他組織。該公司創辦人哈曼說,使用成年動物脂肪細胞的幹細胞來治療慢性病是合理的,因為動物身體用脂肪細胞來製造結疤組織和修補損壞,「我們只是使用身體現存的修補機器,把它濃縮,並把它放在受傷的地方及需要治療的地方,來使其自然痊癒」。

自2003年起,該公司治療了1500隻狗,並計畫今年稍後開始治療貓,全國有超過1500名獸醫可執行幹細胞療法。加州爾灣的獸醫葛塞爾用幹細胞療法治療了40隻狗,狗主人的報告和對止痛藥的要求顯示,其中80%都有正面的反應。

兩項由康乃爾大學研究人員做的研究發現,患骨關節炎的狗在注射幹細胞後,跛行的情況有改善,這些研究都是部分或全部由Vet-Stem公司資助,由該公司研究人員和其他獸醫進行的。

另外,中國報於2009年亦曾報導一位飽受關節炎困擾20年的女士–蕭瑞群(54歲),芙蓉小販同業商會會長李中永的太太,在愛心腎臟專科醫院接受膝蓋軟骨幹細胞治療,解決了多年的困擾。
