August 31, 2006 presentation by Julie Baker and Hank Greely for the Stanford University Office of Science Outreach's Summer Science Lecture Series. Julie Baker, Assistant Professor of Genetics and Hank Greely, Professor of Law and Genetics discuss human embryonic stem cells, one of the most promising, most complicated and most controversial areas of contemporary biomedical research.

The MIT Biology Department core courses all cover the same core material, which includes the fundamental principles of biochemistry, genetics, molecular biology, and cell biology. Biological function at the molecular level is particularly emphasized and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into mul...more

This course explores the basic principles of chemistry and their application to engineering systems. It deals with the relationship between electronic structure, chemical bonding, and atomic order. It also investigates the characterization of atomic arrangements in crystalline and amorphous solids: metals, ceramics, semiconductors, and polymers (including proteins). Topics covered include organic chemistry, solution chemistry, acid-base eq...more

In this lecture, Professor Diamond begins discussing the liver. She notes that the liver is the largest gland in the body and that all the cells in the liver are different. She describes the liver's location below the diaphragm and the liver's four lobe structure. After introducing the liver, Professor Diamond conducts a course review, covering topics from her previous lectures on the muscular system and digestive system.

In this lecture on the male reproductive system, Professor Diamond begins by covering the primary sex organ (the gonad or testis). She discusses its function in producing sperm and testosterone, location within the male body, and the reason it is enclosed in a separate pouch called the scrotum (temperature regulation by the eremasteric muscle). Then she talks about the source of sperm, structure of the testis, in particular, the lobules, s...more

This penultimate lecture concludes the discussion of the male reproductive system. Here Professor Diamond introduces the sex glands, which include the seminal vesicles, prostate and the balbo urethra glades, detailing their location, functions and secretions. These secretions include acid phosphate from the prostate, which is used to detect prostate cancer. She then turns to the penis, diagramming its components, location of glands, purpos...more

Molecular biology of prokaryotic and eukaryotic cells and their viruses. Mechanisms of DNA replication, transcription, translation. Structure of genes and chromosomes. Regulation of gene expression. Biochemical processes and principles in membrane structure and function, intracellular trafficking and subcellular compartmentation, cytoskeletal architecture, nucleocytoplasmic transport, signal transduction mechanisms, and cell cycle control.

In this lecture, Professor Diamond continues her description of the muscular system, describing the gluteal muscles and muscles of the thigh and leg. She also discusses muscle histology. She begins with the gluteal muscles, including the gluteus maximus, gluteus medius, and gluteus minimus. She continues by describing muscles of the thigh, including the quadriceps femoris and the hamstring muscles. She describes the anatomy of the femo...more

Professor Diamond continues her discussion of the nervous system beginning with processes - extensions of the soma. She describes axons, dendrites and the types of synapses: axodendritic, axoaxomic, axosomatic, and dendrodentritic. She then describes how neurotransmitters travel from the presynaptic terminal of an axon to the postsynaptic terminal of a dendrite in an axodendritic synapse. Professor Diamond continues with neuron classifi...more

Professor Diamond continues her discussion of the nervous system beginning with a discussion of myelin-forming oligodendrocytes and Schwann cells, saltatory conduction from the nodes of ranvier, and the similarity of the function of microglia to monocytes. She moves on to describe the development of the neural tube by drawing a cross-section of the neural tube and depicting the changes it undergoes, forming the ventricles of the brain, whi...more

In this lecture, Professor Diamond continues her discussion of the nervous system and begins by reviewing the telencephalon before transitioning into a discussion of the six layers of the neocortex. She discusses the hippocampal-dentate complex, the archicortex, and the temporal lobe, which contains the hippocampus and pyramidal cells along with the fimbrea, fornix, and mammilary bodies. To enhance students' understanding of the neural tu...more
