Myeloid

The term myeloid (before AltGr μύελος -. Myelos, "Mark ", meaning the bone marrow, not the spinal cord) is a collective term for cells of the hematopoietic system, which can not be associated with the lymphatic system. The assignment is done either by a characteristic cell morphology (i.e., the typical microscopic appearance of the cells), or by immunological studies, such as by flow cytometry ( " FACS " ) or immunohistochemistry. This characteristic proteins on the cell surface or in the cytoplasm can be detected, allowing the assignment of the blood cells for myeloid and lymphoid series. Genetic studies may be consulted. Myeloid cells show eg usually no changes in T- cell receptor and immunoglobulin genes, as they are typically found in lymphoid cells.
