I'm working on writing up a report on my research from the last few months, and I'm getting tired of FTPing it to myself back and forth. Therefore, I'm going to save it here along with some commentary, as a little insight into what my life has been about for the last while. This is a work-in-progress.
Introduction
Planaria – free living flatworms of class Turbellaria – have been known for their incredible regenerative capacity since Abraham Trembley and later Peter Simon Pallas first considered them “immortal under the edge of the knife” nearly 250 years ago (Newmark and Sanchèz Alvarado, 2002). Their nearly limitless regenerative plasticity allows a full organism to regenerate from a fragment as small as 1/279 of the original organism. In addition to this fascinating ability, planaria are very interesting as a model organism due to their extreme simplicity yet resemblance to upper organisms: they are bilaterally symmetrical, cephalised, have cute eyespots which function almost identically to more advanced eyes, and possess a central nervous system consisting of paired ganglia and longitudinal nerve cords. However, their eyes are very nearly as simple as possible using the light-detection rhodopsin system standard to most visual organisms, and the planarian contains only three distinct tissue layers. Its circulatory, digestive, and respirtatory systems are virtually nonexistent: as a flatworm it accomplishes these functions via diffusion. The planarian represents a fascinating bridge between extremely complex and extremely simple organisms, making it ideal as a research topic.
