Cell Biology: Concepts, Approaches and Translational Impact
Proposed Syllabus, Spring 2017
COURSE INFO:
Course Organizer: Dr. Pam Cowin <[email protected]>
COURSE GOALS:
Modern cell biology is an exciting discipline relevant to all biologists. In addition, cell biological
techniques are essential for mechanistic analysis and preclinical drug validation and hence the study of
cell biology is also relevant to the fields of translational and regenerative medicine and drug discovery.
Cell biology has played a critical role in the discovery of adult tissue stem cells and reprogramming.
Cell biology covers a broad spectrum ranging from subcellular analysis of organelles, cytoskeletal
complexes and protein trafficking to studies of complex cell interactions and behaviors. Thus cell
biology intersects with and complements the fields of developmental biology, illuminating mechanisms
essential for the formation and maintenance of tissues. It has provided critical insight into understanding
the inappropriate proliferative states and metastatic behavior of tumor cells in cancer biology and the
disintegration of tissues in degenerative pathologies. This course aims to stimulate exploration of
concepts and current approaches in modern cell biology and offers a range of active learning and
participatory modules to achieve this.
COURSE DESCRIPTION:
The course will cover a broad range of topics relevant to cell biology. It emphasizes basic fundamental
cell biology and highlights translational medical applications. The course will cover the following
concepts and themes: cell and molecular interactions governing potency, differentiation and plasticity
among cellular hierarchies, mechanisms of cell adhesion, migration, communication and dynamic
cytoskeletal reorganization in the construction of tissues, regulation of cell proliferation and cell death,
and subcellular protein trafficking and signaling. The aberration of these processes in relevant
pathological situations will also be discussed throughout the course. The lecture/tutorial format will give
students a broad background and the opportunity to engage in discussion on exciting recent data in the
field.
COURSE LOGISTICS:
3 credits.
Two 90-minute lectures/week in SK3 9-10:30am Tuesdays and Thursdays.
One 90-minute small group tutorials on Friday morning. Each group explores a different paper along a
common theme and this is to stimulate a greater breadth of knowledge as a whole by stimulating “after
class” discussion among the student body. There will be one week when in place of the above format
students will be divided into 3 research groups and given free rein to explore present a 30 minute ppt on
a chosen topic to the class.
GRADING:
In this course we focus on achieving education through preparation and active participation by the
students. They are expected to come to class having read set current reviews prior to each of the two
weekly lectures. They are encouraged to bring questions and actively engage with the lecturer in order
to reach a conceptual understanding of the topic. Small group tutorials are an important aspect of this
course where students meet with different faculty in groups of three or four to discuss the concepts
raised by a current paper within a tutorial setting. Students sign up for tutorial group assignments at the
beginning of the course so that they can build this in depth aspect of the curriculum in accord with their
own particular research interests.
There will be a take home essay at the end of the course. Students are allowed to choose from a sign up
list of topics and are also encouraged to suggest a topic to explore in this manner to a faculty lecturer in
the course.
Grading is de-emphasized The goal is that all students will work actively throughout the course to
acquire their own education rather than be tested. This is emphasized at the opening of the course.
Grades are based on preparation for class as judged by their active participation in lectures, ppt
presentations and tutorial discussion, as well as on their take home essay. Lecturers will be asked to
provide feedback on the essay and students may seek guidance while writing it so that the “exam”
becomes an education in itself.
Relevant programs: Stem Cell Biology, Cellular and Molecular Biology, Developmental Genetics,
Molecular Oncology and Immunology, Molecular Pharmacology, Pathobiology, Biomedical imaging
and informatics
Week 1: Stem Cells, Lineage and Plasticity
Goal: To introduce students to the concepts and mechanisms by which cell diversity is generated, maintained
and/or reprogrammed. The first lecture uses intestine to discuss concepts of the stem cell hierarchy and the niche
in generating reserved quiescent as well as activated zones of stem cell activity. It discusses how the stem cells
generate the niche and are regulated by the niche. It introduces the role of Wnt Hh and Notch signaling in these
processes. Colon cancer is discussed as an example of how deregulated stem cell activity predisposes to cancer
and is presented as a careful parsing of the distinction between stem and cancer stem cells. The second lecture
covers the development of ES cells from prior work on teratomas emphasizing the concepts of niche and potency.
Through learning about iPS cells students gain insight into the control of potency and differentiation and the
plasticity of the cellular state. Tutorials: Recent primary literature will be selected to build upon themes of iPS
manipulation, lineage tracing, in vitro models of stem cell and cancer stem cell activity.

Week 2: Extracellular Matrix, Cell-Matrix Mechanotransduction via Integrinmediated signaling and stretch activation of TGF-beta.
The first lecture will cover the large integrin family and the diverse roles of its members in cell-matrix, cell-cell
and clotting interactions. Signaling from kinases and adaptors localized at focal contacts will be covered and the
mechanisms of inside out and outside in signaling at these sites. Structural changes in integrin shape and
clustering that lead to activation will be discussed. The recently emerging role of specific integrins as mechanotransducers essential for stretch-mediated TGF-beta activation and the consequence of this for cell motility, EMT
and feedback loop to matrix synthesis will be introduced. The second lecture will briefly review matrix
composition and the role of fibroblasts in its synthesis and then build upon the first lecture through the paradigm
of Marfan syndrome, which was initially viewed as a genetic disease in which mutations compromised elastic
fibers. More recent work has shown that the elastic fiber defect produces results in loss of docking sites for latent
TGF-beta and BMP and when compromised results in excessive signaling due to failure to sequester and locally
activate these signaling molecules. This illustrates the interconnection and feedback between the matrix
surroundings of cells and signaling that affects their motility and matrix production with pathological
ramifications for multiple genetic syndromes as well as EMT induction in cancer and distortion of niche-induced
stem cell quiescence in other settings.

Week 3: Adhesion, Polarity and Migration
The first lecture emphasizes the role of cell-cell interactions and behaviors in building tissues. The first lecture
will contrast fibroblastic and epithelial social behavior, review the history of experimentation and thought in cell
adhesion form reconstituting sponges to interfering with slime mold aggregation and the contribution of these
model organism studies to the elucidation of the major molecular adhesive mechanisms. We will discuss the
physical molecular and structural basis of cell adhesion with emphasis on dynamic transitory (immunological
synapse) and the relative roles of adherens junctions in initiating epithelial cell adhesion and desmosomes in
reinforcing and stabilizing epithelial associations. The role of the cytoskeleton in regulating cadherin based
adhesion in stem cell niche and its loss, switching and deregulation in EMT and cancers will be covered and its
modulation in morphogenesis such as during convergent extension. The role of beta-catenin as a modulatable link
in cell adhesion and a central signal-transducer-transcriptional factor in Wnt signaling will be reemphasized as
will the role of p120 catenin and kaiso as example of dual feedback regulators of adhesion and transcription. The
second lecture concentrates on cell migration and the role of the GTPases Rho Rac and Cdc42 in lamellipodia,
filopodia and cytoskeletal dynamics. Contact guidance, directed individual and collective cell migrations and
response to gradients will be covered.
