The study conducted a retrospective analysis of various clinical assessments such as physical examination, blood tests, and radiography and monitored the formation of neoplasms, during the 6-month follow-up period in 40 client-owned dogs that received intravenous infusion of adipose-tissue derived MSCs (AT-MSCs) for the treatment of various underlying diseases between 2012 and November 2018. No significant side effects of the MSC therapy were detected by clinical assessment, blood tests, and radiographic examination in the 6-month follow-up period after the first MSC treatment, and no new neoplasms were observed during this period. This study is the first to evaluate the long-term (โ‰ฅ 6 month) safety aspects and risk of tumorigenesis for intravenous allogenic AT-MSC infusion. These results suggested that the allogenic AT-MSC infusion does not have a tumorigenic potential in dogs and confirmed that MSC therapy can be a useful and a relatively safe therapeutic approach in canines.์ค„๊ธฐ์„ธํฌ ์น˜๋ฃŒ๋Š” ์—ฌ๋Ÿฌ ์งˆํ™˜์—์„œ ์น˜๋ฃŒ ํšจ๊ณผ์™€ ์ž„์ƒ์  ์ ์šฉ์— ๋Œ€ํ•ด ์ˆ˜ ๋…„ ๋™์•ˆ ์—ฐ๊ตฌ๋˜์–ด ์™”์œผ๋ฉฐ, ์ตœ๊ทผ ์ˆ˜์˜ํ•™์—์„œ๋„ ๊ทธ์— ๊ด€๋ จ๋œ ์—ฐ๊ตฌ๋“ค์ด ๋ฐœํ‘œ๋˜์—ˆ๋‹ค. ํ•˜์ง€๋งŒ, ๊ฐœ์—์„œ ์ข…์–‘ ํ˜•์„ฑ๋Šฅ์„ ํฌํ•จํ•œ ์žฅ๊ธฐ์  ์•ˆ์ „์„ฑ์„ ํ‰๊ฐ€ํ•œ ๋ณด๊ณ ๋Š” ๊ฑฐ์˜ ์—†๋‹ค. ๋ณธ ์—ฐ๊ตฌ์—์„œ๋Š” ๊ฐœ์—์„œ ๋™์ข… ์ง€๋ฐฉ์œ ๋ž˜ ์ค‘๊ฐ„์—ฝ ์ค„๊ธฐ ์„ธํฌ์˜ ์ •๋งฅ ๋‚ด ํˆฌ์—ฌ์˜ ๋ถ€์ž‘์šฉ์„ ํ‰๊ฐ€ํ•˜๊ณ  ์ข…์–‘ ํ˜•์„ฑ์„ ํฌํ•จํ•œ ์žฅ๊ธฐ ์•ˆ์ „์„ฑ์„ ์กฐ์‚ฌํ•˜๊ณ ์ž ํ•˜์˜€๋‹ค. 2012๋…„์—์„œ 2018๋…„ ์‚ฌ์ด์— ๊ธฐ์ € ์งˆํ™˜ ์น˜๋ฃŒ๋ฅผ ์œ„ํ•ด ์„œ์šธ๋Œ€ํ•™๊ต ๋™๋ฌผ๋ณ‘์› ๋‚ด๊ณผ์— ๋‚ด์›ํ•œ 40๋งˆ๋ฆฌ์˜ ๊ฐœ์—์„œ ์ •๋งฅ ๋‚ด๋กœ ์ค„๊ธฐ์„ธํฌ ํˆฌ์—ฌ ํ›„ ์‹ ์ฒด๊ฒ€์‚ฌ, ํ˜ˆ์•ก๊ฒ€์‚ฌ, ์˜์ƒ๊ฒ€์‚ฌ ๋“ฑ์˜ ๋‹ค์–‘ํ•œ ์ž„์ƒ์  ํ‰๊ฐ€๊ฐ€ ์ด๋ฃจ์–ด์กŒ์œผ๋ฉฐ, ์‹ ์ƒ ์ข…์–‘ ํ˜•์„ฑ ์—ฌ๋ถ€๋ฅผ 6๊ฐœ์›”์˜ ์ถ”์  ๊ธฐ๊ฐ„ ๋™์•ˆ ์กฐ์‚ฌํ•˜์˜€๋‹ค. ์ฒซ ๋ฒˆ์งธ ์ค„๊ธฐ์„ธํฌ ํˆฌ์—ฌ ํ›„ 6 ๊ฐœ์›”์˜ ์ถ”์  ๊ธฐ๊ฐ„ ๋™์•ˆ ์ž„์ƒ ํ‰๊ฐ€, ํ˜ˆ์•ก ๊ฒ€์‚ฌ ๋ฐ ๋ฐฉ์‚ฌ์„  ๊ฒ€์‚ฌ ๊ฒฐ๊ณผ ์‹ฌ๊ฐํ•œ ๋ถ€์ž‘์šฉ์€ ๋ฐœ๊ฒฌ๋˜์ง€ ์•Š์•˜์œผ๋ฉฐ, ์ด ๊ธฐ๊ฐ„ ๋™์•ˆ ์ƒˆ๋กœ์šด ์‹ ์ƒ๋ฌผ์€ ๊ด€์ฐฐ๋˜์ง€ ์•Š์•˜๋‹ค. ๋ณธ ์—ฐ๊ตฌ๋Š” ์ •๋งฅ ๋‚ด ๋™์ข… ์ง€๋ฐฉ์œ ๋ž˜ ์ค‘๊ฐ„์—ฝ ์ค„๊ธฐ์„ธํฌ ์ฃผ์ž…์— ๋Œ€ํ•œ 6๊ฐœ์›” ์ด์ƒ์˜ ์žฅ๊ธฐ์  ์•ˆ์ „์„ฑ ๋ฐ ์ข…์–‘ ๋ฐœ์ƒ ์œ„ํ—˜์„ฑ์„ ํ‰๊ฐ€ํ•œ ์ฒซ ์—ฐ๊ตฌ์ด๋‹ค. ๋˜ํ•œ ๋™์ข… ์ง€๋ฐฉ์œ ๋ž˜ ์ค‘๊ฐ„์—ฝ ์ค„๊ธฐ์„ธํฌ ์ฃผ์ž… ์‹œ ๊ฐœ์—๊ฒŒ ์ข…์–‘ ํ˜•์„ฑ๋Šฅ์ด ํ™•์ธ๋˜์ง€ ์•Š์•˜์œผ๋ฉฐ ์ค„๊ธฐ์„ธํฌ ์น˜๋ฃŒ๋Š” ๊ฐœ์—์„œ ์œ ์šฉํ•˜๊ณ  ๋น„๊ต์  ์•ˆ์ „ํ•œ ์น˜๋ฃŒ ๋ฐฉ๋ฒ•์ด ๋  ์ˆ˜ ์žˆ์Œ์„ ์‹œ์‚ฌํ•˜์˜€๋‹ค.1.
