noun, plural: lymphocytes

The white blood cell of the blood derived from the stem cells of the lymphoid series of vertebrates


Lymphocytes are a type of white blood cells. There are two main groups and a null group of lymphocytes. The two main groups are B lymphocytes and T lymphocytes. The B lymphocytes are involved in the production of antibodies in the humoral immune response. The T lymphocytes participate in the cell-mediated immune response. The null group of lymphocytes include the natural killer cells, cytotoxic cells involved in the innate immune response of vertebrates. Lymphocytes are derived from the stem cells of the lymphoid series, thus the name. Lymphocyte count is typically part of the complete blood cell count. It is expressed as the percentage of lymphocytes to the total number of white blood cells. An increase in the normal range of lymphocytes is known as lymphocytosis whereas a decrease is called lymphocytopenia.

Word origin: French lymphe, from Latin lympha (water, water nymph), from Ancient Greek númphē (nymph) + New Latin cyta, from Ancient Greek kútos (vessel, jar)

CFSE proliferation assay

... the staining. However, in the results from Flow Cytometry of day 0 samples, (i.e. freshly stained and not cultured) there are 2 separated picks in lymphocyte population. Does anyone encounter this problem before and what could be the reasons. And next question is that I tried to titrate the amount ...
