真相还是假象?神经所杨辉CELL论文再遭质疑( 四 )



同样也面临JCI一文质疑的张康向《知识分子》表示 , “选择四月龄甚至更大的rd10小鼠 , 已经检测不到感光细胞和视网膜电图信号 , 再结合GFAP-CRE追踪系统 , 我们认为后形成的感光细胞和功能由穆勒胶质细胞转化而来” 。

他也同时承认 , 后期需要完善体内追踪系统 , 包括使用更长或全长GFAP启动子、double cre , 设置严格的对照组 , 足够密集的取样时间点和全面的分析手段 , 逐级追踪穆勒胶质细胞向神经细胞的转化过程 , 对形成的细胞进行全面的分析 , 以证明所看到的神经细胞真的由穆勒胶质细胞而来 。

付向东就此也向《知识分子》表示 , 对于JCI文质疑 , 他们正设计实验全面解决AAV泄漏的问题 。

截止发稿时 , 杨辉没有回应《知识分子》的电邮询问 。

“我相信如此拉风的研究一定会有人重复 , 只有重复才能做出最终的判断 。 ” 陈功说 。
