Hybridomas are formed from which type of cells?

Hybridomas are formed from which type of cells?

• A. B lymphocytes
• B. T lymphocytes
• C. Bone marrow cells
• D. Macrophages

Answer: (A)

Hybridomas are specialized cells that are generated through the fusion of B lymphocytes with myeloma (cancer) cells. This process allows the resulting hybridoma to possess the ability to produce a specific antibody, as the B lymphocyte contributes its unique antibody-producing capabilities, while the myeloma cell provides the ability to divide indefinitely. The uniqueness of hybridomas lies in their ability to produce monoclonal antibodies, which are identical antibodies produced by cloned hybridoma cells. These monoclonal antibodies are invaluable in research, diagnostics, and therapeutic applications, as they can specifically target antigens. While T lymphocytes, bone marrow cells, and macrophages serve crucial roles in the immune system, they do not play a direct role in the production of hybridomas. T lymphocytes are primarily involved in the adaptive immune response, bone marrow cells are important for producing various blood components, and macrophages function mainly in phagocytosis and antigen presentation. Thus, the correct answer highlights the specific involvement of B lymphocytes in the formation of hybridomas.
