Article Title: Bioluminescent xenograft model of acute myeloid leukemia for immunotherapy preclinical studies.
Article Snippet: Accurate in vivo models that recapitulate both acute myeloid leukemia (AML) progression and human immune responses are essential for the preclinical testing of novel immunotherapies.. In this study, we developed and validated a bioluminescent NSG-SGM3 PBMC-THP-1 xenograft model that does not require cytotoxic or irradiation preconditioning and allows simultaneous assessment of leukemia burden, human chimerism, and immune checkpoint expression.. Based on six consecutive experiments, we established that GFP/Luc-THP-1 is the preferred clone for the NSG-SGM3 strain when co-transplanted with healthy donor peripheral blood mononuclear cells (PBMC).

(A) Heatmap of normalized log2 fold change of chemokine receptor gene expression from homeostatic epithelial (KTC) and Langerhans cells (LC). Cells isolated through FACS and sequenced through bulk RNA‐seq. Each column represents an independent sample, and each row is assigned to a specific gene. Red indicates maximum expression and blue indicates minimum expression. n = 4 mice (B) Experimental design for drug treatment. Starting on wound induction day, drug was injected once a day intradermally at the ear near the wound site. Control mice received vehicle (1% DMSO) injections. Wounds were imaged at wound closure (5 days after wound induction), and candidate drugs were further analyzed for migration dynamics through time‐lapse at 2 days after wound induction. Revisit imaging (camera icon) was performed on Day 0 and 5. Timelapse imaging (video icon) was performed on Day 2.
