Description
  • Bylo nalezeno pět stádií vývoje vitelocytu. První stádium odpovídá nedospělé buňce obsahující ribozomy a mitochondrie. Druhé vývojové stádium je charakterizováno přítomností granulovaného endoplazmaického retikula a Golgiho komplexu, formováním kapiček lipidů a periferní buněčné cytoplasmy. Vitelocyty třetího stádia představují akumulaci obalených granulí a lipidových kapek. Během čtvrté fáze jsou zformovány granule a lipidové kapénky a rozety a-glycogenu se akumulují. Dospělé vitelinní buňky jsou charakterizovány přítomností velkého množství tukových kapének s glykogenem v centru cytoplazmy, zatímco shluky obalených granul jsou spíše periferně. Intersticiální tkáň vitelinních buněk P. japonicus jsou syncytiální s dlouhým cytoplazmatickým výběžkem dosahujícím mezi vitelinní buňky. (cs)
  • Five stages of vitellocyte development have been distinguished. The first stage corresponds to immature cells containing ribosomes and mitochondria. The second stage of development is characterized by the appearance of granular endoplasmic reticulum and Golgi complexes, formation of shell globules and lipid droplets at the periphery of the cell cytoplasm. Vitellocyte of the third stage presents accumulation of shell globules and lipid droplets. During the fourth stage, shell globule clusters are formed, and lipid droplets and rosettes of a-glycogen are accumulated. Mature vitelline cells are characterized by a great number of lipid droplets with glycogen in the centre of the cytoplasm, whereas shell globule clusters are situated more peripherally. The interstitial tissue of vitelline follicles of P. japonicus is syncytial with long cytoplasmic projections extending between vitelline cells.
