  2. Precursor cell - Wikipedia

    en.wikipedia.org/wiki/Precursor_cell

    In cell biology, precursor cells—also called blast cells—are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells .

  3. Cellular differentiation - Wikipedia

    en.wikipedia.org/wiki/Cellular_differentiation

    Three basic categories of cells make up the mammalian body: germ cells, somatic cells, and stem cells.Each of the approximately 37.2 trillion (3.72x10 13) cells in an adult human has its own copy or copies of the genome except certain cell types, such as red blood cells, that lack nuclei in their fully differentiated state.

    BLAST (biotechnology), Basic Local Alignment Search Tool, an algorithm used in bioinformatics; Blast cell or precursor cell, in cytology, a type of partially differentiated, usually unipotent cell; Blast disease, a disease of cereal crops; Blast injury, a complex type of physical trauma resulting from direct or indirect exposure to an explosion

  6. BLAST (biotechnology) - Wikipedia

    en.wikipedia.org/wiki/BLAST_(biotechnology)

    In bioinformatics, BLAST (basic local alignment search tool) [3] is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.

  7. Proerythroblast - Wikipedia

    en.wikipedia.org/wiki/Proerythroblast

    A proerythroblast (or rubriblast, or pronormoblast) is a precursor cell to the normoblast (nucleated red blood cell), as the earliest of four stages in its development. In histology, it is very difficult to distinguish it from the other "-blast" cells (lymphoblast, myeloblast, monoblast, and megakaryoblast).

  8. Myeloblast - Wikipedia

    en.wikipedia.org/wiki/Myeloblast

    These cells descend from the primitive reticulum cells, which are found in the stroma of the marrow. There is also an intermediate phase between the myeloblast and these primitive reticulum cells, namely the hemocytoblast. At this time several developing blood cell lines are available, like erythropoiesis and thrombopoiesis.

  9. Blastoma - Wikipedia

    en.wikipedia.org/wiki/Blastoma

    Cytology of a precursor (blast) cell, with features often seen even after partial differentiation into any of the more specific cell types. Wright's stain. A blastoma is a type of cancer, more common in children, that is caused by malignancies in precursor cells, often called blasts.
