Summary
Hollow-fiber bioreactors enable large-scale expansion of gene-modified human T cells. This method overcomes nutrient and waste limitations, significantly increasing cell yield compared to traditional methods.
Area of Science:
- Regenerative Medicine
- Cell Therapy
- Bioprocessing
Background:
- Traditional cell culture methods (well-plate and flask-based) are insufficient for the large-scale expansion of gene-modified human T cells required by regenerative medicine.
- Cell proliferation is often limited by nutrient and oxygen supply and waste product accumulation in static culture environments.
Purpose of the Study:
- To review process development changes necessary for meeting high-yield T cell expansion demands.
- To discuss the utilization of hollow-fiber bioreactors for overcoming limitations in cell expansion.
Main Methods:
- Utilizing hollow-fiber bioreactors for cell culture.
- Implementing perfusion feeding strategies.
- Enhancing gas exchange and waste removal (lactate).
Main Results:
- Perfusion feeding, improved gas exchange, and lactate removal increased T cell yield from 10.8E+09 to over 28E+09 cells within 10 days.
- Active cell retention in the bioreactor improved environmental management.
Conclusions:
- Hollow-fiber bioreactors, with optimized feeding and environmental control, can overcome constraints limiting cell expansion.
- This technology facilitates significantly higher yields of gene-modified T cells for therapeutic applications.

Thin-Walled Hollow Shafts
586
In analyzing a thin-walled hollow shaft subjected to torsional loading, a segment with width dx is isolated for examination. Despite its equilibrium state, this segment faces torsional shearing forces at its ends. These forces are quantitatively described by the product of the longitudinal shearing stress on the segment's minor surface and the area of this surface, leading to the concept of shear flow. This shear flow is consistent throughout the structure, indicating a uniform distribution of...

Classification of Skeletal Muscle Fibers
59.6K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Heat and Free Expansion
3.0K
The work done by a thermodynamic system depends not only on the initial and final states but also on the intermediate states—that is, on the path. Like work, when heat is added to a thermodynamic system, it undergoes a change of state, and the state attained depends on the path from the initial state to the final state. Consider an ideal gas cylinder fitted with a piston. When the cylinder is heated at a constant temperature, the gas molecules absorb energy and expand slowly in a...

Thermal Expansion
5.7K
The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal expansion, which is the change in size or volume of a given system as its temperature changes. The most visible example is the expansion of hot air. When air is heated, it expands and becomes less dense than the surrounding air, which then exerts an upward force on the hot air to, for example, make steam and smoke rise, and hot air balloons float. The same behavior happens in all liquids and gases,...

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Optimization Problems

Optimization problems often involve identifying maximum or minimum values under specific constraints. A well-known example is determining the longest horizontal pipe that can be moved around a right-angled corner, where a 3-meter-wide hallway meets a 2-meter-wide hallway. This scenario, common in architectural design and industrial transport, can be understood conceptually through geometric and trigonometric reasoning.To visualize the problem, consider the pipe as a straight line that touches...
