Modulation of the cardiomyocyte contraction inside a hydrostatic pressure bioreactor: $\textit{in vitro}$ verification of the Frank-Starling law [PDF]

open access: yesBioMed Research International 2015;2015:542105, 2019
We have studied beating mouse cardiac syncytia $\textit{in vitro}$ in order to assess the inotropic, ergotropic, and chronotropic effects of both increasing and decreasing hydrostatic pressures. In particular, we have performed an image processing analysis to evaluate the kinematics and the dynamics of those pressure-loaded beating syncytia starting ...

Hepatocyte Aggregates: Methods of Preparation in the Microgravity Simulating Bioreactor Use in Tissue Engineering [PDF]

open access: yesarXiv, 2008
Tissue Engineering concerns the three-dimensional cell growth so that bio-artificial tissues could be created and used for transplantation. The recently expressed concerns from the Tissue Engineering research community for a re-direction of the research activities necessitate the proposition of new methodologies. We propose a methodology that has to do

Data-driven and Physics Informed Modelling of Chinese Hamster Ovary Cell Bioreactors [PDF]

open access: yesarXiv, 2023
Fed-batch culture is an established operation mode for the production of biologics using mammalian cell cultures. Quantitative modeling integrates both kinetics for some key reaction steps and optimization-driven metabolic flux allocation, using flux balance analysis; this is known to lead to certain mathematical inconsistencies.

Hollow Fiber Bioreactors for In Vivo-like Mammalian Tissue Culture [PDF]

open access: yes, 2016
Tissue culture has been used for over 100 years to study cells and responses ex vivo. The convention of this technique is the growth of anchorage dependent cells on the 2-dimensional surface of tissue culture plastic.

Developing Quorum Sensing‐Based Collaborative Dynamic Control System in Halomonas TD01

open access: yesAdvanced Science, EarlyView.
A standardized and streamlined inducer‐free quorum sensing (QS)‐based collaborative dynamic control pattern is developed for sufficient gene expression control in Halomonas TD by mixing two engineered cells, cells A and B. Proof‐of‐concept studies are designed to test the dynamic control performance in mixed cultures in fed‐batch conditions.
