美国研究人员日前在《自然-材料》杂志网络版上刊登的研究报告首次证明,细胞的物理特性可以代替某些化学复合物,加快成熟细胞重新“编程”、从而转变为同胚胎干细胞一样的诱导多能干细胞的进程。负责这项研究的美国加利福尼亚大学伯克利分校生物工程系教授李松说,这项研究成果是干细胞研究和微生物研究领域的重要进展。研究人员从人体皮肤和实验鼠耳朵提取成纤维细胞,用一种可对成熟细胞进行“再编程”的混合液,在有着宽10微米、高2微米的平行 A few days ago, a study published by the American researchers in the online edition of Nature-Materials magazine showed for the first time that the physical characteristics of cells can replace some chemical compounds and accelerate the reprogramming of mature cells to become the same as that of embryonic stem cells Of induced pluripotent stem cells. Li Song, a professor of bioengineering at the University of California at Berkeley in charge of the study, said the research is an important advance in stem cell research and microbiology research. The researchers extracted fibroblasts from the human skin and the ears of mice using a “reprogramming” of the mature cells in a mixture of 10 μm wide and 2 μm high parallel
