Quality System and LOI Updates (August ’25)

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….

Since the last TraCe-bMPS update in April, we continued to explore different conditions to optimize the μSiM hVasc-SkM systems to obtain stable results.  Enhanced imaging for PDMS beams with Rhodamine staining  Previously we established a MATLAB program that detects the border of the PDMS beams and converts the movement of the PDMS beam from myobundle…

The μSiM Vasc-SkM Microphysiological development can be separated into 4 parts: Media tuning for integrated culture Force sensing element setup Assembly of the μSiM Vasc-SkM and setting up the perfusion Transendothelial Electrical Resistance (TEER) measurement of the Vast component Work has been done on the first 2 parts. Media tuning for integrated culture In order…
