Subnucleolar location of fibrillarin and variation in its levels during the cell cycle and during differentiation of plant cells The nucleolar protein fibrillarin has been studied in onion cells; it is detected as an Mr 37,000 protein by immunoblotting using a human autoimmune serum... A Cerdido...
(CO) show that the cell clusters have more of the enzyme and, presumably, higher metabolic activity than the surrounding fiber regions. The details of the parcellation pattern of this nucleus in humans and monkeys are quite comparable (Florenceet al.,1989), suggesting the significance of the ...
Do onion cells have a nucleus? The epidermal cells of onions provide a protective layer against viruses and fungi that may harm the sensitive tissues. ... Each plant cell has a cell wall, cell membrane, cytoplasm, nucleus, and a large vacuole. Thenucleusis present at the periphery of the...
The increasing pressure of cell on cell, the breakdown of intercellular membranes in the lens nucleus, the slow conversion of soluble to insoluble protein, and the dehydration and accumulation of pigment (urochrome) all lead to optical and histologic densification of the nucleus and a nuclear catar...

There is considerable confusion about the nomenclature of this cell group (for discussion of this see Usunoff et al., 1997). Originally described as interstitial cells by Cajal (1909), this cell group was later considered part of the paratrigeminal nucleus of Chan-Palay (1978). Paxinos and ...
