AIM Biotech Reviews Techniques to Improve T Cell Efficacy Using the Company’s Organ-on-a-Chip Technology (3D Cell Culture Plate)

Key Takeaways
  • AIM’s 3D cell culture chips are helping researchers bring about the next-generation of T-Cell therapies
  • A technique used by one research group revealed a certain type of engineered T-Cell had lower off-target effects and was more effective at killing cancer cells
  • This is another example of how AIM’s predictive platform is being used as a beneficial tool in cancer research to improve the probability of success

Singapore & Boston, MA -- July 26, 2021 –- AIM Biotech is providing an update on a technique using its organ-on-a-chip platform to further improve T cell efficacy. The Company’s 3D cell culture chips are being used in preclinical research to better understand Adoptive T Cell Immunotherapy, and, specifically, improve cancer treatment options with allogeneic (universal donor) engineered T Cells that could have fewer off target effective and greater capacity to kill cancer cells.

With Adoptive T Cell Immunotherapy, T cells are engineered to make them express proteins that recognize the cancer cells. These proteins are called recombinant T Cell Receptors or rTCR. In some cases, the expression of rTCR is affected by the expression of endogenous T Cell Receptors, or eTCR. The mix of rTCR and eTCR in the same cell, can lead to the attack of healthy off-target cells. That is something to avoid when treating cancer. Healthy organs should not be attacked by the therapy used.

Preece and colleagues implemented an extra modification on the T cells to prevent the expression of eTCR. The scientist took advantage of CRISPR, a technique that allows targeted specific changes in the DNA. Using CRISPR, they silenced the expression of eTCR on engineered T cells expressing rTCR. Later, both T cells, with or without eTCR expression, were tested on AIM Biotech’s organ-on-a-chip platform.

Scientists injected tumor cells in a collagen matrix in the central chamber of the chip. Later, T cells were added to the side medium channels. They measured the number of T cells that migrated to the tumors, and also their capacity to kill the cancer cells.

They found that both types of the engineered T cells migrated similarly in proximity to the cancer cells. But when looking at the capacity of killing those cells, T cells lacking eTCR were more than two times more effective than T cells expressing the eTCR proteins.

AIM’s engineering approach to biology is providing insights designed to increase the probability of success in drug development. AIM’s organ-on-a-chip technology is a powerful tool that faithfully reproduces clinically relevant data and insightful diagnostics.


AIM gives researchers 3D human biology-on-a-chip to revolutionize their preclinical drug discovery and molecular research. At its core is the AIM Chip, a specialized 3D microfluidics device that makes it easy to generate relevant human data from disease-specific assays. Researchers are able to create their own assays or apply validated protocols, which include angiogenesis, vasculogenesis, metastasis, immuno-oncology, and 3D culture of tumor samples. AIM Biotech is located in Singapore and Boston, MA.
