초록
한국 곰소만산 암컷 바지락(Ruditapes philippinarum)의 난모세포의 발달 및 퇴화과정 중 일어나는 미세구조적 변화에 관해 기술하였다. 난소소낭은 영양성분을 저장하는 포상결체조직세포(VCT cell)들의 기질에 의해 둘러쌓여 있다. 난 형성과정 초기에 초기난황형성난모세포와 보조세포 (follicle cell)들 사이에 desmosome-like gap junction들이 나타났다. 난황형성과정은 골지체, 미토톤드리아, 조면소포체가 결합되어 작용하는 자율합성과정을 통하여 일어나며, 난황막 형성에 앞서 난황형성과정의 초기와 난모세포 퇴화에 없어서는 안될 역할을 하는 것으로 나타났다: 보조세포들은 식세포작용 및 난모세포 퇴화로부터 유래되는 산물들의 세포내소화에 관여한다. 이들의 기능은 난황형성에 필요한 난황전구체들로 전환이 일어나게 한다. 또한 보조세포들은 난황형성난모세포들이 이용하는 글리코겐과 지방적들을 세포질 내에 영양물질로 축적, 저장할 수 있다. 보조세포들은 난모세포가 퇴화되는 기간 중에는 난모세포의 붕괴를 위해 리소조옴 체제를 가지며, 영양물질 저장을 위해 세포질 내에 존재하는 여러 종류의 파고소옴(phagosome)들을 흡수하였다. 그러나 보조세포들은 난황형성과정에서 난황형성을 위한 난황전구체의 주된 공급원이 아니라고 추정된다.
Abstract
Ultrastructural changes occurring during the course of development and degeneration of oocytes in female Ruditapes philippinarum (Adams & Reeve, 1850) are described for clams collected from Gomso Bay, Korea. During the early stages of oogenesis, desomosome-like gap junctions localized between the early vitellogenic oocyte and the follicle cells. Vitellogenesis occurs through a process of autosynthesis, involving the combined activity of the Golgi complex, mitochondria and rough endoplasmic reticulum, and heterosynthesis in which extraovarian precursors are incorporated into oocytes by endocytotic activity, involving the basal region of the early vitellogenic oocytes prior to the formation of the vitelline envelope. The follicle cells appear to play an integral role in vitellogenesis and oocyte degeneration: phagocytosis and intracellular digestion of products originating from oocyte degeneration. These functions can permit a transfer of yolk precursors necessary to vitellogenesis, and they can accumulate nutrients in the cytoplasm, as glycogen and lipids, which can be employed by the vitellogenic oocyte. During the period of oocyte degeneration, follicle cells may have lysosomal system for breakdown, and resorb various phagosomes in the cytoplasm for nutrient storage. But follicle cells probably are not the major source of yolk precursors in vitellogenesis.
