鹦鹉在进化史上发展出了独特的颚肌。假颌肌（M. pseudomasseter）是鹦鹉特有的颚肌，它完全覆盖了牙杆的外侧。在先前的研究中，我提出了基于组织学分析的颅神经嵴细胞（NCC）发育调节的变化与这种新型颚肌产生的相关性的假设（Tokita [2004] J Morphol 259:69-81）。本研究利用免疫组织化学技术对鹦鹉胚胎发生过程中颅神经嵴细胞（NCCs）的分布和迁移模式进行了研究，旨在进一步了解颅神经嵴细胞在伪马齿鹦鹉进化过程中的作用，并为鸟类发育早期颅神经嵴细胞迁移的相对可塑性提供新的信息。颅骨NCC发育的基本性质在雏鸟和鹦鹉之间基本保持不变。在这两种情况下，颅ncc从神经管的背端向腹侧方向迁移。在他们的颅骨ncc中确定了三个主要人群。这些细胞的迁移途径在雏鸟和鹦鹉之间几乎相同。主要的区别在于颅骨NCC迁移的相对时间。在鹦鹉的早期发育阶段，颅骨NCC向第一咽弓的迁移比小鸡要早。颅骨NCC迁移的这种时间转移可能会影响鹦鹉颚肌肉的结构模式，从而产生新的肌肉，如假咬肌。j .

Parrots have developed unique jaw muscles in their evolutionary history. The M. pseudomasseter, which completely covers the lateral side of the jugal bar, is regarded as a jaw muscle unique to parrots. In a previous study, I presented a hypothesis on the relevance of modifications in the regulation of cranial neural crest cell (NCC) development to the generation of this novel jaw muscle based on histological analyses (Tokita [2004] J Morphol 259:69–81). In the present study, I investigated distribution and migration patterns of cranial neural crest cells (NCCs) through parrot embryogenesis with immunohistochemical techniques to further understand the role of cranial NCCs in the evolution of the M. pseudomasseter, and to provide new information on the relative plasticity in cranial NCC migration at early stages of avian development. The basic nature of cranial NCC development was mostly conserved between chick and parrot. In both, cranial NCCs migrated from the dorsal tip of the neural tube in a ventral direction. Three major populations were identified in their cranial NCCs. Migration pathways of these cells were almost identical between chick and parrot. The principal difference was seen in the relative timing of cranial NCC migration. In the parrot, cranial NCC migration into the first pharyngeal arch was more advanced than in the chick at early stages of development. Such a temporal shift in cranial NCC migration might influence architectural patterning of parrot jaw muscles that generates new muscle like M. pseudomasseter. J. Morphol. © 2005 Wiley‐Liss, Inc.
