We use a new cell marker to study cell lineage of the epidermis, oenocytes and ventral muscles in the Drosophila abdomen. We find that while the epidermal cells and the oenocytes share common precursors until late in development, the muscles derive from a separate lineage. Marked clones in the muscles, but not in the epidermis and oenocytes, can occasionally extend between neighbouring segments, supporting a previous hypothesis that mesoderm cells may not be determined as to segment.
我们使用一种新的细胞标记物来研究果蝇腹部表皮、oenocytes和腹侧肌肉的细胞谱系。我们发现，虽然表皮细胞和oenocytes在发育后期之前共享共同的前体，但肌肉来自一个独立的谱系。肌肉中的标记克隆（而非表皮和oenocytes中的标记克隆）偶尔会在相邻节段之间延伸，这支持了之前的一个假设，即中胚层细胞可能在节段方面尚未确定。
