海鞘胚胎中肌肉细胞的谱系已有充分记录。在 B 系卵裂球中，B7.4 细胞在 44 细胞阶段仅限于产生肌肉，而 B7.8 和 B7.5 细胞在 64 细胞阶段仅限于产生肌肉。在本研究中，我们解决了有关肌肉特异性结构基因转录起始时间的三个问题：（i）肌肉特异性基因转录起始是否与发育命运限制相关；（i）肌肉特异性基因转录起始是否与发育命运限制相关； (ii) 如果时间上存在关系，是否适用于 B7.4、B7.5 和 B7.8 亚系； (iii) 两个肌肉特异性基因（一个针对肌动蛋白，另一个针对肌球蛋白重链）是否表现出相同的时间表达模式。
The lineage of muscle cells in the ascidian embryo is well documented. Of the B‐line blastomeres, B7.4 cells become restricted to give rise to muscle at the 44‐cell stage, whereas B7.8 and B7.5 cells become restricted to muscle at the 64‐cell stage. In this study we addressed three issues concerning the timing of initiation of muscle‐specific structural gene transcription: (i) whether the initiation of the transcription of muscle‐specific genes is correlated to that of developmental fate restriction; (ii) if there is a relationship in the timing, whether it is applicable to B7.4‐, B7.5‐ and B7.8‐sublineages; and (iii) whether two muscle‐specific genes, one for actin and the other for the myosin heavy chain, show the same pattern of temporal expression.
