substances of which something is composed or made.
The development and advancement of societies have been intimately tied to the
members ability to produce and manipulate materials to fill their needs.
o Provide control and standardization
Establish control over physiochemical culture parameters during
cell/tissue culture, bioreactors offer potential for improving the quality of

Spiderman: Superhuman balance and equilibrium
The vestibular system controls our balance and equilibrium. The hair cells in the
vestibular apparatus of the inner ear create a labyrinth of receptors in the semi-circular canals
Human body has 10 major organ systems
Tissue: to weave, a collection of cells and ECM that perform a function
ECM is big part of tissue, interconnected network of macromolecules
o Regulate cellular fate processes such as apoptosis, migration wit
Describes the evolution and development of form, structural changes that we observe
during development and elucidation of underlying mechanisms
Harnessing natural morphogenesis is fundamental in assembling complex organs
Human development is
Triad: cells, scaffold, growth factors
Freeze injury: some matrix left, no scar tissue, no contraction
Burn injury: matrix destroyed, scar tissue, wound contraction
ECM fiber diameter: 50-500nm
Cell: 5-25 um
Xenogenic: using animal cells in a human
Cellular Fate Processes
Differentiation is measured by changes in gene expression
o Process by which a cell undergoes phenotypic changes to an overtly specialized
o Involves a change in the set of genes that are expressed in the cell
Cell and Tissue Properties
Basic modes of analysis
Light microscopy- allows for examination of cellular features with 0.2
Cells can be better visualized, visualize transparent features with
contrast enhancement technique-
3.1 The origin of the resting potential
All cells have resting membrane potential, but not same value
o Associated with modulation of cellular activity
o Certain cells of the body (excitable cells) can use rapid changes in membrane potential
Chapter 13 and 18 Notes
Chapter 13 Scaling up for Ex Vivo Cultivation
o We have discussed the interplay among cellular-far processes (cell replication,
migration, differentiation, and apoptosis)
o These processes are properly ba
1.2 Physical Foundations of Physiology I: Pressure-Driven Flow
Forces produces flows
o External and internal movement is a hallmark of human life
o Transport of material is described as a flow or a flux
o Flow depends on the area: flux is flow per unit ar
