“主體對移植細(xì)胞或移植物的排斥是醫(yī)學(xué)研究人員面臨的巨大障礙。”該研究的*、密蘇里大學(xué)動(dòng)物科學(xué)和生物化學(xué)教授邁克爾·羅伯茨對物理學(xué)家組織網(wǎng)表示:“研究表明,豬會(huì)接受并‘擁抱’移植細(xì)胞,如此一來,我們現(xiàn)在能進(jìn)一步加快干細(xì)胞治療的研究了。”
在實(shí)驗(yàn)中,研究人員將人體多功能干細(xì)胞移植進(jìn)由該大學(xué)抗原抗體生理學(xué)教授蘭德爾·普拉瑟研制出的轉(zhuǎn)基因豬體內(nèi)。普拉瑟專門制造出的這種豬擁有的免疫系統(tǒng),使其能接受所有的移植物而不會(huì)出現(xiàn)排斥。研究表明,豬并不排斥外來的人體干細(xì)胞,而且,這些干細(xì)胞在“新家”也能蓬勃地生長發(fā)育。普拉瑟說,用豬進(jìn)行實(shí)驗(yàn),取得此類成功非常重要,因?yàn)榕c其它實(shí)驗(yàn)動(dòng)物相比,豬與人類更接近。
普拉瑟解釋道:“很多醫(yī)學(xué)研究人員更喜歡使用豬進(jìn)行研究,因?yàn)閺慕馄蕦W(xué)上來說,豬比老鼠更接近人類;豬的大小也更接近人類;而且,豬與人對健康威脅的反應(yīng)比較類似。這意味著,在豬身上進(jìn)行的測試和治療更可能與在人體上進(jìn)行的研究產(chǎn)生類似的結(jié)果。”
羅伯茨表示:“研究為的科學(xué)家們打開了一扇新的窗戶,這意味著,我們朝著用干細(xì)胞治療和治愈多種慢性疾病更近了一步。”
"Subjects' rejection of transplanted cells or implants is a huge hurdle for medical researchers." Michael Roberts, a professor of animal science and biochemistry at the University of Missouri, who led the study, told the Physicists Network: "Recent research shows that, Pigs will accept and 'hug' the transplanted cells, and as a result, we can now further accelerate the study of stem cell therapy. "
In a recent experiment, researchers transplanted human pluripotent stem cells into transgenic pigs developed by Randall Prather, a professor of antibody and antibody physiology at the university. The pig's immune system, which Prather specifically manufactures, allows it to accept all implants without rejection. Studies have shown that pigs do not exclude foreign human stem cells, and that these stem cells can also thrive in "new home." Prasser said it is important to experiment with pigs to make such successes because pigs are closer to humans than other experimental animals.
Prasser explains: "Many medical researchers prefer to use pigs for research because anatomically speaking, pigs are closer to humans than mice; pigs are also much closer in size; and pigs respond to health threats This means that testing and treatment in pigs is more likely to produce similar results than research conducted in humans. "
Roberts said: "The latest research opens up a new window for scientists around the world, which means we are one step closer to treating and curing many chronic diseases with stem cells."
