 The Department of Anatomy and Cell Biology offers a
program leading to the Doctor of Philosophy degree in the
medical sciences with specialization in cell and develop-
mental biology. The core curriculum provides instruction
in these fields including related areas of molecular biology.
Training is also offered in structural approaches to cell
biology utilizing light and electron optics, including ad-
vanced state-of-the-art, three-dimensional digital methods,
confocal optical microscopy, digital image processing, and
computer graphics. The Department is a founding member
of the new campuswide Center for Structural Biology.
 Specificareas of research include protein turnover, modi-
 fication, transport and localization, cell interactions in
 development, cell proliferation, intercellular adhesion, ex-
 tracellular matrix, secretion, cytoskeleton, nuclear struc-
 ture and function, cell-surface receptor-ligand events, en-
 docytosis, regulation of renal transport and aspects of
 reproductive biology.
 Applicants should have a strong background in biology,
 chemistry, or physics and have taken undergraduate courses
 in organic chemistry, calculus, physics, cell biology, and
 biochemistry. Deficiencies may be remedied during the
 firstyear of graduate study.The Department does notaccept
 students into a program of study leading to the degree of
 Master of Science.
