Question

oRelate cell-cell interactions (or loss of) and cell-ECM interactions to cellular movement

oPropose experiments to determine the function of ECM or junction components in particular cellular/structural processes.

Answer 1

The cell-cell interaction is the direct interactions between the cell surfaces and it helps in the development of the multi-cellular organisms. It helps the cells to communicate with each other and helps in exchanging materials. The interaction between cells helps in sending or receiving signals that is needed for the survival of the cells. The cell to cell stable interactions are facilitated by help of tight junctions, anchoring junctions, gap junctions, direct contact signaling etc.

The cell ECM interactions are very important in development of the organism. The cell interact with extra cellular membranes and helps in the developmental process. There is a cross link between the cells and molecules of the extracellular matrix which helps in the movement of different ions and molecules through it.
