Their technique allows the authors to define the intrinsic spatial and temporal sequence or “hierarchy” of molecular events involved in the dynamic behavior of a cellular superstructure—in this case, the leading edge—in the absence of the confounding compensatory mechanisms underlying cellular adaptation. • Cellular adaptations can be induced and/or regulated at any of a number of regulatory steps including receptor binding, signal transduction, gene transcription or protein synthesis • The most common morphologically apparent adaptive changes are – Atrophy (decrease in cell size) – Hypertrophy (increase in cell size) – Hyperplasia (increase in cell number) Cell Injury and Adaptation 1 – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 1bf2fb-MzUyO If you continue browsing the site, you agree to the use of cookies on this website.
