Abstract
This study compares philtral development in the normal fetus with philtral development in specimens lacking normal philtral landmarks. Distinct differences in the structure of the upper lip were discovered between the two groups using a histological comparison. A new mechanism for the structural basis of the philtrum is proposed on the basis of these differences.
摘要
本研究比较了正常胎儿的人中发育与缺乏正常人中标志的标本的人中发育。通过组织学比较发现两组之间上唇结构存在明显差异。基于这些差异，提出了一种关于人中结构基础的新机制。
