“It is produced in the cytoplasm of lactiferous cells along with amino acids, phospholipids, carbohydrates, and proteins.”

“The zebrafish egg is about 0.7mm in diameter, with the cytoplasm and nucleus at the animal pole sitting upon a large mass of yolk.”

“The tumor cells had elongated blunt-ended nuclei and acidophilic fibrillary cytoplasm.”

“Scoring was done as previously described in Figure 1B. Only the percentage of unmixed cytoplasms category is graphed.”

“Failure of mating pairs to mix cytoplasms during conjugation is diagnostic of a complete block in cell fusion.”

“Viruses differ from bacteria because they do not have cytoplasms or cell organels.”
