Diffusion Across a Sheep Red Blood Cell Membrane
This cell membrane physiology laboratory uses sheep red blood cells to determine: (1) the isotonic and hemolytic molar concentrations of electrolytes and nonelectrolytes, and degree of electrolyte dissociation; (2) the diffusion rate of penetrating molecules of varying size and lipid solubility; and (3) the relationship of molecular size, number of hydroxyl groups, and partition coefficient to diffusion rate. Student research teams then design an experiment using the acquired techniques to deter

Cell Fractionation in Tetrahymena
To illustrate cell fractionation, nuclei are isolated from the ciliated protozoan, Tetrahymena thermophila. A table top clinical centrifuge is used for the fractionation steps and the procedure is monitored microscopically using a differential stain. To determine the efficiency of the procedure, cell and nuclear counts are determined with a hemacytometer. To quantify DNA, the Diphenylamine Reaction is carried out and the amount of DNA per nucleus is calculated.

Cell Biology and Cancer
Cancers result when genes required for normal cell function are mutated and the resulting cells undergo other changes ultimately leading to uncontrolled division. This session reveals new information on normal cell function, proto-oncogenes and tumor suppressor genes and their role in the cell cycle, and current research in drug design for specific cancers.

Kohn lecture 2010 - Cell cycle control
The growth and reproduction of all living organisms are dependent on the cell cycle, the process which leads to cell division. Uncontrolled division of cells is important for disease particularly cancer. Two events, S-phase and mitosis, are common to all cell cycles and are necessary for the two newly divided cells to receive a full complement of genes.

Douglas Melton, Harvard University: "Stem Cell Challenges in Biology and Public Policy" - April 10,
Douglas Melton will discuss the biology and public policy challenges surrounding stem cell research. The potential of human embryonic stem cells for understanding human development and finding new therapies will be presented. Dr. Melton is a cell and molecular biologist as well as an advocate of embryonic stem cell research. His research focuses on the developmental biology of the pancreas. One of the primary goals of his work is to understand how human embryonic stem cells differentiate into pa
