Abstract

Lipid A induced bone marrow cells derived from lipopolysaccharide responder strain C3H/HeN to release a component to the extracellular fluid that enhanced DNA synthesis of splenocytes derived from the lipopolysaccharide nonresponder strain C3H/HeJ. The mitogenic component was not selected when C3H/HeN splenocytes were used instead of bone marrow. The target cell in splenocyte populations responding to the mitogenic component released by lipid A-stimulated bone marrow cells is a B cell, as judged by the corresponding of individual cells undergoing DNA synthesis determined by autoradiograph and the presence of surface immunoglobulin detected by immunofluorescence. The mitogenic factor is heat-labile, sensitive to trypsin, and intensive to RNase.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
