The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Area of Science:

Space biology
Immunology
Cellular physiology

Background:

Space travel poses risks to human physiology, particularly the immune system.
The effects of microgravity on T cells, crucial for adaptive immunity, are not fully understood.
Existing research often uses limited models, like 2D cultures, which don't fully represent tissue environments.

Purpose of the Study:

To investigate how simulated microgravity affects circulating and tissue-resident T cells.
To compare the impact of microgravity on T cells in 2D versus 3D cell culture models.
To assess differences between resting and activated T cells under simulated microgravity.

Main Methods:

Utilized a random positioning machine to simulate microgravity.
Employed both 2D cell culture and 3D collagen matrices to model circulating and tissue-resident T cells.
Analyzed T cells in both resting and activated states.

Main Results:

Three-dimensional (3D) cell culture significantly reduced the impact of simulated microgravity on T cell transcriptome and nuclear irregularities compared to 2D culture.
Simulated microgravity had a lesser effect on activated T cells than on resting T cells.
3D models offer a more protective environment for T cells under microgravity conditions.

Conclusions:

Three-dimensional cell culture systems provide a more accurate representation of T cell behavior in microgravity.
Activated T cells exhibit greater resilience to simulated microgravity than resting T cells.
Findings offer insights for improving astronaut immune health during space missions.
