英国的研究人员声称,老鼠的内耳细胞可以体外培养,这一发现将为听觉研究带来一场新的革命。 该发现将帮助科研人员准确找出决定耳朵发育的基因片段,并方便地用药物医治听力损伤。如果此项技术可扩展到人类细胞的话,将会使耳蜗移植更趋成功,甚至可以替换损伤的耳细胞。 布里斯托大学的亨利及其同事已经从胚胎鼠的耳蜗中分离出了这种细胞。鼠耳蜗是内耳中负责觉察声音的部分。鼠类的遗传基因决定其细胞分裂可以随 British researchers claim that mouse inner ear cells can be cultured in vitro, a finding that will bring a new revolution to auditory research. The discovery will help researchers pinpoint the gene segments that determine ear development and ease the use of medications to heal hearing loss. If this technology can be extended to human cells, it will make cochlear transplantation more successful, and even replace injured ear cells. Henry and colleagues at the University of Bristol have isolated the cells from the embryos’ cochlea. The mouse cochlea is the part of the inner ear responsible for perceiving the sound. The genetic basis of the mouse determines that its cell division can follow
