Detailed explanation-1: -Lymphocytes are mature, infection-fighting cells that develop from lymphoblasts, a type of blood stem cell in the bone marrow. Lymphocytes are the main cells that make up lymphoid tissue, a major part of the immune system. Lymphoid tissue is found in lymph nodes, the thymus gland, the spleen, the tonsils, and adenoids.
Detailed explanation-2: -Lymphoid Stem Cells, also called Common Lymphoid Progenitor Cells, give rise to a class of leukocytes known as lymphocytes, which include the various T cells, B cells, and natural killer (NK) cells, all which function in immunity.
Detailed explanation-3: -Common Precursor of B and T Lymphocytes B and T lymphocytes arise from a common ancestral cell-lymphoid progenitor or common lymphoid precursor-2 (CLP-2). The common B-and T-cell progenitor can be found in the bone marrow.
Detailed explanation-4: -All cells of the immune system are derived from the pluripotent hematopoietic stem cell found in the bone marrow. This pluripotential stem cell gives rise to lymphoid stem cells and myeloid stem cells.
