Detailed explanation-1: -B cells are part of the immune system and develop from stem cells in the bone marrow. Also called B lymphocyte. Blood cell development. A blood stem cell goes through several steps to become a red blood cell, platelet, or white blood cell.
Detailed explanation-2: -Each B cell produces a single species of antibody, each with a unique antigen-binding site. When a naïve or memory B cell is activated by antigen (with the aid of a helper T cell), it proliferates and differentiates into an antibody-secreting effector cell.
Detailed explanation-3: -Most of us assume that B lymphocytes, or B cells, got their name because they mature in the bone marrow: “B” for bone marrow. However, this is not really the case. The “B” in B cells comes from the Bursa of Fabricius in birds. The Bursa of Fabricius (BF) was first described by Fabricius ab Aquapendente in the 1600s.
