The cell cycle, which is composed of four main phases, is responsible for planning and the development of these cells. This cycle is also composed of all the steps required for the reproduction of a eukaryotic cell.The four phases of a cell cycle include: G...
Gametal cells are produced in the organisms in which sexual reproduction and alternation of generations occur. Primordial germ cells divide through meiotic division and produce gametic cells. In a gametic cell, a number ofchromosomesbecome half than that of its somatic type. A new living body is...
Distinct types of T-cell help for the induction of a humoral immune response to Streptococcus pneumoniae. Trends Immunol. 22:308.Snapper CM, Shen Y, Khan AQ, Colino J, Zelazowski P, Mond JJ, et al. Dis- tinct types of T-cell help for the induction of a humoral immune response to ...
Cell-free RNA from liquid biopsies can be analyzed to determine disease tissue of origin. We extend this concept to identify cell types of origin using the Tabula Sapiens transcriptomic cell atlas as well as individual tissue transcriptomic cell atlases in combination with the Human Protein Atlas RN...

Multiplexed fluorescence in situ hybridization techniques have enabled cell-type identification, linking transcriptional heterogeneity with spatial heterogeneity of cells. However, inaccurate cell segmentation reduces the efficacy of cell-type identifica
We have used different P(Gal4) lines to drive Green Fluorescent Protein (GFP) in distinct populations of cells within the Drosophila antenna. Mz317::GFP, a marker for cell body and perineural glia, labels the majority of peripheral glia. An additional ~30 glial cells detected by GH146::GFP...
The cell size ranges from 0.1 to 0.5 µm in diameter. The hereditary material can either be DNA or RNA. Prokaryotes generally reproduce by binary fission, a form of asexual reproduction. They are also known to use conjugation – which is often seen as the prokaryotic equivalent to sexual ...
