摘要: Cytoplasmic granulo-fibrillar masses, usually termed nucleolus-like bodies (NLB) or nuages, have been described in several different cell types. They are sometimes associated with a mitochondrial arrangement, this association often being marked during certain phases of the oocyte cycle. In Xiphophorus helleri, NLB consist fibrillar and granular material that gradually becomes more meiotic prophase I, is arrangements diplotene dictyate meiosis.
