近年的研究表明哺乳动物出生后前庭耳石器毛细胞可以再生。本项研究采用扫描电镜技术，以豚鼠为研究对象，首次证实豚鼠不仅耳石器毛细胞而且半规管壶腹嵴毛细胞也可以自发再生。再生毛细胞散在分布于前庭上皮内，而某些脊椎动物再生毛细胞聚积在生长区内。结果提示豚鼠所有的前庭器，包括耳石器和壶腹嵴都保持着自发的毛细胞再生。 Recent studies have shown that mammalian posterior vestibular otolith cells can be regenerated after birth. In this study, the use of scanning electron microscopy techniques to guinea pigs for the first time to study, guinea pigs not only for the first time confirmed that the epididymis hair cells and semi-regulatory ampullate ridge hair cells can spontaneously regenerate. Regenerative hair cells scattered in the vestibular epithelium, and some vertebrate regenerative hair cells accumulate in the growth zone. The results suggest that all guinea pig vestibular devices, including the otolith and ampulla, maintain spontaneous hair cell regeneration.
