The result of the present study support our hypothesis that the tension caused by phonation(vocal fold vibration) after birth stimulate the vocal fold stellate cells in the anterior and posterior maculae flavae to accelerate production of extracellular matrices and form the vocal ligament, Reinke's space, and characteristic layered structure of the human vocal fold mucosa. This suggests that the vocal fold vibration(phonation) after birth and mechanotransduction of the vocal fold stellate cells in the maculae flavae are important factors in the growth and development of the human vocal fold mucosa.The vocal fold stellate cells in the human maculae flavae are desmin-positive cells with perinuclear vitamin A droplets and show the morphological features of the cells included in the proposed diffuse stellate cell system. The vocal fold stellate cells are considered to be a new category of cells in the human vocal fold. The maculae flavae are believed to be special microenvironments or niches, that nurture a pool of vocal fold stellate cells

本研究结果支持我们的假设，即出生后发声（声带振动）引起的张力刺激黄斑前部和后部的声带星状细胞，加速细胞外基质的产生，形成声带韧带、赖因克间隙、和人类声带粘膜的特征性分层结构。这表明出生后声带振动(发声)和黄斑声带星状细胞的力传导是人体声带粘膜生长发育的重要因素。核周维生素 A 液滴的结蛋白阳性细胞，并显示了所提出的弥散星状细胞系统中包含的细胞的形态特征。声带星状细胞被认为是人类声带中的一类新细胞。黄斑被认为是特殊的微环境或生态位，可培育声带星状细胞池
