Which term is also known as a cellular response? __________ is a diagnostic test to detect damage or malformations of the lymphatic vessels. The firm uses FIFO inventory accounting. If the cell moves away from the extracellular matrix, signaling through these receptors stops, and the cell undergoes apoptosis.
