Title: Micro- and nano-bioreactors for control of cell behaviour and
tissue genesis
Abstract: Shear stress is known to regulate a number of endothelial cell
functions. In particular,
cell shape and orientation, and cytoskeleton protein production, secretion
and organization.
Therefore, understanding the effects of shear on endothelial cells in
microchannels is necessary
for and prior to the development of a microvascular network, which is a
significant and challenging
goal in the engineering of large three-dimensional artificial tissue
structures. In order to create
a 3D microvascular network, firstly, a multishear microdevice capable of
rapidly screening a wide
range of shear stresses (0.7-130 dynes/cm2, covering both physiological and
pathological states)
was developed. It was used to probe for optimal flow and shear stresses for
the culture of endothelial
cells in microchannels. Leading on from this we have developed a
microdevice with a 'multi-rung'
microvascular network design that has uniform fluid flow profiles in all
its channels. HUVECs were
cultured in the microvascular microdevice, resulting in a fully patent,
three-dimensional endothelial
cell (microvascular) network. A 24 h perfusion study was conducted using
this device and
immunofluorescence staining revealed a contiguous, 3D endothelial monolayer
throughout the network.
Most recently we have moved this microvascular network into a degradable
microdevice format,
allowing for the observation of endothelial sprouting from the 'rungs'
under perfusion flow. I will also
provide a brief overview of the other activities within my laboratory
developing cell-based diagnostic
microdevices and microbioreactors to elucidate the microenvironmental cues
required for human
embryonic stem cell expansion and lineage specificity and to visualize and
quantify cell migration on
virgin surfaces in controlled microenvironments. Lastly, I will touch on
our work investigating the
flow of non-Newtonian fluids (polymer solutions and biological fluids) in
microfluidic devices presenting
complex geometrical features.
