"The Fountain of Life: From Dolly to Customized Embryonic Stem Cells, Fall 2007"
" During development, the genetic content of each cell remains, with a few exceptions, identical to that of the zygote. Most differentiated cells therefore retain all of the genetic information necessary to generate an entire organism. It was through pioneering technology of somatic cell nuclear transfer (SCNT) that this concept was experimentally proven. Only 10 years ago the sheep Dolly was the first mammal to be cloned from an adult organism, demonstrating that the differentiated state of a m

Plant Growth Responses to a Nitrogen Gradient
Techniques used in setting up field experiments to study the growth responses of herbaceous plants to a resource gradient will be discussed and demonstrated in the field. Methods of setting up light and nutrient gradients, soil sampling, seed collection and preparation, data collection and analysis will be included. Participants will observe on-going studies in the field at the Cedar Creek Natural History Area, and view slides of smaller scale Puse experiments.

"Regenerative Medicine: from Bench to Bedside, Spring 2010"
"Regenerative medicine involves the repair and regeneration of tissues for therapeutic purposes, such as replacing bone marrow in leukemia, cartilage in osteoarthritis or cells of the heart after a heart attack. In this course, we will explore basic mechanisms of how cells differentiate into specific tissues in response to a variety of biologic signaling molecules. We will discuss the use of such factors for in vitro tissue production. We will also study the cellular mechanisms involved in the c
