Quality System and LOI Updates (August ’25)

The following site may be useful to draw to people’s attention when specifying objectives on the Etaluma: https://www.microscope.healthcare.nikon.com/microtools/resolution-calculator/#Focus I have configured a custom resolution calculation using the sensor data supplied by Etaluma, here exemplified at 10x/0.3NA: To take account of the shorter tube lens (which gives ¼ magnification expected cf Nikon 200mm tube) I have…

Introduction Over the past few months, I have been characterizing and comparing iPSC-derived monocytes (iMonocytes) with peripheral blood-derived (PB) monocytes. As I wrap up these experiments, we’ve decided to look at marker expression on iMonocytes and PB monocytes once they have been polarized to macrophages by culturing the iMonocytes or PB monocytes with HTEN051 fibroblasts…

Work in progress … **************** T cell–Engaging Immunotherapies Pose a Predictable but Complex RiskT cell–engaging bispecific antibodies (BsAbs), particularly those targeting CD3 and a tumor-associated antigen, have emerged as a powerful class of immunotherapies. These agents leverage endogenous T cells to induce targeted tumor cell death, often achieving deep and durable responses in hematologic malignancies….

CRE_Bispecific_Antibody_CRS_and_ICANS_Neurotoxicity_Guidance_Feb2024 51899285fnl_Immunotoxic Potential of PharmaceuticalsWe are considering Bispecific T cell engagers (BiTEs) [1] as an alternative to a CAR T driven cytokine release as an immunotherapy focused DDT. BiTEs are monoclonal antibodies engineered to have one arm that recognizes a T Cell surface antigen and another that recognizes a tumor antigen. There are number of…

We’ve long speculated that adding fluid flow over our tissue models would reduce the concentration of pro-inflammatory factors secreted in response to inflammatory challenges, dampening the overall inflammatory state compared to static culture. We now have evidence that this is true and the results are important as benchmarks for our future studies. In response to…
