Alejandro Sanchez-Alvarado (Stowers Institute for Medical Research) Part 1: History of Regeneration
Regeneration has fascinated philosophers and scientists since the beginning of history. The wide but uneven distribution of regenerative capacities among multicellular organisms is puzzling, and the permissive/inhibitory mechanisms regulating this attribute in animals remain a mystery. In the first part of this lecture, I will provide a general history of regeneration research from ancient Greece to the beginning of the 20th century. Key concepts will be introduced in their appropriate historical context, and many of the unanswered questions put forward by the problem of regeneration will be discussed.
Alejandro Sánchez Alvarado moved from the University of Utah to the Stowers Institute for Medical Research in 2011.
