Course Description

As living beings, we encounter every kind of traumatic event from paper cut to dental extraction to myocardial infarction. We must possess ways to heal damaged tissues to survive. While some animals are able to regrow complete body parts following injury (such as the earthworm who grows a new head following bisection), humans are sadly incapable of such feats. Our means of recovery following tissue damage consists largely of repair rather than pure regeneration. Thousands of times in our lives, a meticulously scripted but unseen wound healing drama is enacted, with cells serving as actors, extra-cellular matrix as the setting, and growth factors as the means of communication. This course presents the main features of this fascinating drama as it is enacted in healthy patients, and describes ways in which the drama ends badly and healing is not achieved.
