A novel vocal fold bioreactor capable of delivering physiologically relevant, vibratory stimulation to cultured cells is constructed and characterized. This dynamic culture device, when combined with a fibrous poly(ε-caprolactone) scaffold, creates a vocal fold-mimetic environment that modulates the behaviors of mesenchymal stem cells.

Fermentors are used to increase culture yield and productivity of bioengineered cells. After screening multiple microbial or animal cell culture candidates in shake flasks, the next logical step is to increase the selected culture’s biomass with the fermentor. This video demonstrates the setup and operation of a typical benchtop bioreactor system.

Bioreactors are used to grow organisms in large volumes, thereby enabling the production of mass quantities of the target product. These reactors can be batch reactors, which contain all of the components needed for cell growth, or continuous reactors, which have inlet and outlet ports allowing for the addition of fresh growth media and the removal of cell waste. This video presents batch and continuous reactors and demonstrates the use of bioreactors to grow bacteria in the laboratory.

Chondrogenesis from stem cells requires fine tuning the culture conditions. Here, we present a magnetic approach for condensing cells, an essential step to initiate chondrogenesis. In addition, we show that dynamic maturation in a bioreactor applies mechanical stimulation to the cellular constructs and enhances cartilaginous extracellular matrix production.

Static Equilibrium - I

A rigid body is said to be in dynamic equilibrium when both its linear and angular acceleration are zero, relative to an inertial frame of reference. This means that a body in equilibrium can be moving, but only when its linear and angular velocities are constant. A rigid body is said to be in static equilibrium when it is at rest in the selected frame of reference. The distinction between static equilibrium (e.g., a state of rest) and dynamic equilibrium (e.g, a state of uniform motion) is...
FAQs
Temperature, pH, oxygen availability, nutrient composition, and incubation time can each affect how cells, tissues, or microorganisms perform in culture. Adjusting these factors gives researchers a defined way to examine changes in viability, growth, differentiation, or product formation. Controlling the variables also helps separate the effects of culture conditions from the biological behavior being studied.
The comparison reveals how a stationary culture environment differs from one shaped by fluid movement or perfusion. Researchers can assess whether operating conditions alter cell viability, tissue development, biomaterial behavior, or product formation. This side-by-side approach is particularly useful when determining which environmental features support a desired biological outcome in bioengineering.
A stationary environment provides a straightforward reference condition for studying biological materials under defined settings. Because researchers regulate factors such as pH, temperature, nutrients, oxygen availability, and incubation time, they can connect observed changes to specific culture conditions. This makes the system useful for evaluating growth, differentiation, tissue development, and other biological responses.
Researchers should define the culture conditions relevant to their biological question, including temperature, pH, oxygen availability, nutrient composition, and incubation time. Maintaining these factors as intended supports consistent observation of cell, tissue, or microorganism behavior. The selected conditions should match the outcome being evaluated, such as viability, expansion, differentiation, tissue development, or product formation.
This platform is useful when researchers need to examine cell expansion, tissue development, or the performance of a biomaterial under controlled culture conditions. It can provide a practical setting for evaluating how cells or tissues respond over an incubation period. Results may help identify conditions associated with improved viability, growth, differentiation, or biological material formation.
Experiments can show how defined culture conditions influence viability, growth, differentiation, and product formation. In bioengineering, these measurements support assessment of cell expansion, tissue development, and biomaterial performance. When results are compared with those from dynamically operated systems, they can also clarify which aspects of the culture environment are associated with particular biological outcomes.
