Dr Mamoun Ahram Faculty of Medicine Second year Second semester 20142014 Principles of Genetics and Molecular Biology The extracellular matrix What is it The extracellular matrix fills the spaces between cells and binds cells and tissues together Types. . by Dr. . Vani. Gupta . . Definition and Classification of cell junction. Cell junction is the connection between the neighbouring cells or the contact between the cell and extracellular matrix.. 2.3.1, 2.3.2: Liver cell. 2.3.3: Electron micrograph of liver cell (rat). Glycogen. 2.3.4: Prokaryotic VS Eukaryotic cell. FEATURE. Prokaryotic cell. Eukaryotic cell. DNA. Naked DNA. DNA associated. with proteins. The Extracellular Matrix. What is the extracellular matrix?. Extra (E) cellular (C) matrix (M). Outside/outer of the cell surroundings within which something is contained. The part of animal tissue (outside of the cells) that provides. Write. Molecules can pass through the cell membrane in four ways. Directly through the membrane (phospholipid bilayer). Membrane Channels. Carrier Molecules. Vesicles. Write. Cell transport can be categorized into two major groups. By Becky . The Cell. Cytology. is the study of the structure and functions of cells.. The cell was first discovered by Robert Hooke while viewing a dried cork.. The cells have been researched for 175 years.. Cell Migration and Adhesion. Team Members. Marta Bechtel. Christine Hohmann.

Most cells synthesize and secrete materials that are external to the plasma membrane. These extracellular structures include:. Cell walls of plants. The extracellular matrix (ECM) of animal cells. Intercellular junctions. A cell is the basic structural and functional unit of living organisms.. The activity of an organism depends on the collective activities of its cells.. Continuity of life has a cellular basis.. Chemical Components of Cells. Focus on Integrins. John Cooper. Dept of Biochemistry & Molecular Biophysics. www.cooperlab.wustl.edu. jacooper@wustl.edu.

In most of the connective tissues the macromolecules are secreted by fibroblast (Fig. 4.9). In some . Plasma membrane. Regulates what goes in and out of the cell….
