Acute Myeloid Leukemia (AML) PBMC Donors: Disease-State Portfolio

AML Donor Cells for Drug Discovery and Cell Therapy Research

Acute myeloid leukemia (AML) is one of the highest-priority indications for next-generation cell therapy development — CAR-T programs targeting CD33, CD123, FLT3, NKG2D ligands, and combination antigen strategies are in active development, facing the challenge of finding tumor-selective antigens in a disease where target antigens are also expressed on normal hematopoietic progenitors.

AML donor PBMCs from OrganaBio support immune profiling, pharmacodynamic assays, and translational research in this indication. All material is for research use only (RUO).

AML Immune Biology and Research Applications

Immune evasion in AML

AML is characterized by robust immune evasion mechanisms — tumor cells downregulate NKG2D ligands, upregulate immune checkpoint ligands (PD-L1, CD47 “don’t eat me” signaling), and create an immunosuppressive bone marrow microenvironment. Peripheral blood immune cells in AML patients reflect this systemic immune suppression:

  • T cell exhaustion with PD-1, TIM-3, and LAG-3 co-expression
  • NK cell dysfunction characterized by reduced cytotoxic activity and receptor downregulation
  • Expansion of myeloid-derived suppressor cells (MDSCs) in peripheral blood
  • Altered monocyte phenotypes including immunosuppressive polarization states

Starting material quality for CAR-T research

AML patients face the most significant T cell quality challenges of any CAR-T indication. Prior induction and consolidation chemotherapy, bone marrow disease involvement, and the age demographics of AML (median diagnosis age over 60) all affect T cell fitness. AML donor PBMCs allow researchers to characterize starting material biology, model manufacturing feasibility, and test activation and expansion protocols in disease-relevant conditions.

NK cell therapy

NK cells have natural activity against AML blasts through NKG2D-dependent recognition and missing-self mechanisms. AML is a leading indication for allogeneic NK cell therapy development. Peripheral blood NK cells from AML patients — and from HLA-mismatched healthy donors used for allogeneic products — are both relevant research tools for this application.

Myeloid biology

For programs targeting the myeloid compartment directly — CD47/SIRPα checkpoint inhibition, CD123-directed therapies, myeloid reprogramming approaches — AML donor PBMCs provide the disease-relevant monocyte and myeloid progenitor populations that are absent from healthy donor collections.

Clinical Annotation

AML donors from OrganaBio are characterized with annotation relevant to translational research:

  • Confirmed AML diagnosis with FAB classification where available
  • Cytogenetic and molecular risk classification (favorable/intermediate/adverse risk) where documented
  • Treatment status at collection: newly diagnosed (pre-treatment), remission, relapsed/refractory
  • Prior treatment history (induction regimens, transplant history)
  • Blast percentage at diagnosis where documented
  • Age, sex, and relevant comorbidities

Treatment-naive donors collected at diagnosis preserve the intact disease immune phenotype before chemotherapy-induced normalization. Relapsed/refractory donors reflect the immune biology of the most therapeutically challenging patient population.

Available Products and Ordering

AML donor material is available in cryopreserved format. Standard product is whole PBMCs from mononuclear cell isolation. Cell count per vial and subset composition data available on request. All material is for research use only.

AML donor availability reflects the clinical reality of the indication — active enrollment is ongoing. Contact OrganaBio’s scientific team to discuss molecular subtype requirements, treatment history parameters, cell count minimums, and current inventory status.

Frequently Asked Questions

Why are PBMC donors with AML used in hematological oncology research?

Acute myeloid leukemia (AML) is a disease of myeloid progenitor cells, but it profoundly alters the immune microenvironment in peripheral blood and bone marrow. AML donor PBMCs are used in research studying: immune evasion mechanisms employed by leukemic blasts (PD-L1 expression, NKG2D ligand shedding, HLA downregulation), T cell exhaustion and dysfunction in the AML immune microenvironment, NK cell activity and ADCC assay development for AML-targeting therapies, and mechanistic studies of CD33, CD123, FLT3, and other AML target antigens on primary patient cells. For CAR-T and bispecific antibody programs targeting AML antigens, primary patient cells provide the most relevant target cell source.

What is the risk of leukemic blast contamination in AML donor PBMCs, and how is it managed?

At diagnosis, peripheral blood from AML patients may contain circulating leukemic blasts. Depending on the WBC count and blast percentage, density gradient isolation will capture blasts in the PBMC fraction — they are mononuclear cells with a density that overlaps the PBMC layer. OrganaBio’s AML donor clinical annotation includes peripheral blood blast percentage at collection and diagnosis, which allows researchers to select donors with lower blast contamination for assays where the blast population would confound results. For assays specifically targeting blasts (e.g., CAR-T killing assays using AML patient T cells against autologous blasts), donors with measurable circulating blasts are the appropriate choice. Contact OrganaBio with your specific blast percentage requirements when requesting AML material.

How do post-treatment AML donor PBMCs differ from diagnosis-stage material?

Post-induction chemotherapy AML donors — those in remission or in the consolidation phase — have very different peripheral blood immune profiles than at-diagnosis donors. After induction, blast percentage drops to below 5% (MRD criteria) or to undetectable, normal myeloid and lymphoid cell counts are reconstituting, and the T cell compartment is recovering from the chemotherapy-induced lymphopenia. Donors in durable complete remission have largely reconstituted immune systems with low blast contamination but may retain evidence of prior immune dysfunction (persistent T cell exhaustion markers, altered Treg frequency) from the disease and treatment. For assays studying immune recovery after AML therapy or evaluating residual immune dysfunction, post-treatment donors at defined time points after induction completion are more appropriate than active-disease donors.

What immune cell populations are most studied in AML donor PBMCs?

The most research-active populations in AML donor PBMCs: NK cells — studied for their defective cytotoxicity in AML patients versus healthy donors, with ligand-receptor incompatibility between AML blasts and donor NK cells being a key research area; CD8+ cytotoxic T cells — studied for exhaustion state, antigen-specific recognition of leukemia-associated antigens (LAAs), and response to checkpoint inhibition; regulatory T cells — elevated in AML and associated with immune suppression; and monocytes/MDSCs — myeloid-derived suppressor cells are elevated in AML and contribute to immune evasion. OrganaBio can provide subset prevalence data for AML donors on request to help researchers select donors with appropriate cell frequencies for their specific assay requirements.

Are AML donor PBMCs from OrganaBio available for research and what documentation is provided?

OrganaBio’s AML donor PBMCs are available for research use only. Clinical annotation covers: AML subtype (FAB/WHO classification where available), cytogenetic and molecular risk stratification (FLT3-ITD, NPM1, IDH1/2 mutation status where known), treatment history, current disease status (active, CR1, relapsed/refractory), blast percentage at collection, and time since last therapy. COA documentation includes cell count, viability, and any subset data requested at ordering. For researchers studying specific AML genetic subtypes relevant to their drug target or therapy modality, OrganaBio can assist with donor selection from the annotated pool.
