Circulating lymphoblasts

WebImmunophenotyping (on bone marrow or peripheral blood if circulating lymphoblasts are present) using flow cytometry is required to determine whether leukemic lymphoblasts are lymphoid or myeloid in origin, and to detect clinically important cell surface antigens (e.g., CD20).

A lymphoblast is a modified naive lymphocyte with altered cell morphology. It occurs when the lymphocyte is activated by an antigen (from antigen-presenting cells) and increased in volume by nucleus and cytoplasm growth as well as new mRNA and protein synthesis. The lymphoblast then starts dividing two to four times every 24 hours for three to five days, with a single lymphoblast making approximately 1000 clones of its original naive lymphocyte, with each clone sharing the … share with catch windows 10Weblymph circulation: the slow passage of lymph through the lymphatic vessels and glands. share with catch windowsWebCirculation of Lymph with Flow Chart.
