Spontaneous tumor regression mediated by human T cells in a humanized immune system mouse model

Human CD34+ cell isolation Human fetal liver (FL) samples were obtained from Advanced Biosciences Resources (Alameda, CA) with proper consent. FL samples were cut in small fragments, treated for 25 min at 37 °C with Collagenase D (100 ng/mL; Roche). The cell suspension was prepared, and the human CD34+ cells were separated by…

Breadth of SARS-CoV-2 neutralization and protection induced by a nanoparticle vaccine

Animals and immunizations The study protocol and all veterinarian procedures were approved by the Bioqual IACUC per a memorandum of understanding with the Duke IACUC, and were performed based on standard operating procedures. Macaques studied were housed and maintained in an Association for Assessment and Accreditation of Laboratory Animal Care-accredited…

A cell-based phenotypic library selection and screening approach for the de novo discovery of novel functional chimeric antigen receptors

Cell lines and culture Unless stated otherwise, all tumor target cell lines were sourced from the ATCC via LGC Standards. Human endogenous mesothelin (MSLN)-positive target cell lines H-226 (lung carcinoma, MSLN+, ATCC® CRL-5826™) and AsPC-1 (ATCC CRL-1682), and MSLN-negative Raji control cells (ATCC CCL-86) were cultured in RPMI-1640 Glutamax (Life Technologies,…
