Understand the question: The problem is asking which cell type is derived from the lymphoid cell line. To solve this, we need to know the difference between the lymphoid and myeloid cell lines and which cells originate from each.
Recall the concept of hematopoiesis: Hematopoiesis is the process by which all blood cells are formed from hematopoietic stem cells in the bone marrow. These stem cells differentiate into two main progenitor cell lines: the lymphoid cell line and the myeloid cell line.
Identify the lymphoid cell line: The lymphoid cell line gives rise to lymphocytes, which include B lymphocytes (B cells), T lymphocytes (T cells), and natural killer (NK) cells. These cells are primarily involved in adaptive and innate immune responses.
Identify the myeloid cell line: The myeloid cell line gives rise to other types of white blood cells, such as neutrophils, monocytes, eosinophils, basophils, and red blood cells and platelets. These cells are involved in innate immunity and other physiological functions.
Compare the options: Neutrophils, monocytes, and eosinophils are derived from the myeloid cell line, while B lymphocytes are derived from the lymphoid cell line. Therefore, the correct answer is B lymphocyte.
