Chronic Lymphocytic Leukemia (CLL) Bone Marrow Mononuclear Cells
About:Chronic Lymphocytic Leukemia (CLL) Bone Marrow Mononuclear Cells - cryopreserved BMMCs isolated from clinically confirmed CLL donors. Marrow infiltration pattern (nodular, interstitial, or diffuse) carries prognostic value and marrow biopsy supports diagnosis confirmation and cytopenia workup. Ideal for microenvironment and prognostic marker studies. Stratification by IGHV mutation status, cytogenetics, and infiltration pattern.
About Chronic Lymphocytic Leukemia (CLL) Bone Marrow Mononuclear Cells
Chronic Lymphocytic Leukemia (CLL) Bone Marrow Mononuclear Cells for Leukemia Research
Chronic lymphocytic leukemia (CLL) bone marrow mononuclear cells (BMMCs) are isolated by density-gradient separation from bone marrow aspirate, capturing the full spectrum of marrow-resident hematopoietic stem, progenitor, and precursor cells that peripheral blood samples do not contain. Samples come from consented donors under IRB-approved protocols, each clinically diagnosed with CLL — a chronic lymphoproliferative disorder with marrow involvement.
CLL Biology and Why Bone Marrow
- CLL is characterized by clonal accumulation of mature-appearing B lymphocytes, and while diagnosis is often made from peripheral blood, marrow biopsy remains important for confirming diagnosis, evaluating cytopenias, and assessing disease burden.
- The pattern of marrow infiltration – nodular, interstitial, or diffuse – carries independent prognostic value, with diffuse infiltration associated with more advanced disease and marrow failure.
- IGHV mutation status and cytogenetic abnormalities (including del(17p) and del(11q)) are key prognostic and predictive markers assessed alongside marrow and peripheral blood studies.
- The marrow microenvironment, including stromal and nurse-like cells, supports CLL cell survival and is an active target of research into disease persistence and drug resistance.
- Targeted therapies including BTK inhibitors and BCL-2 inhibitors have created demand for marrow-derived material in pharmacodynamic and resistance studies.

Where can I find your complete catalog?
You can find our full product catalog here.
How long can samples be stored?
Storage depends on sample type but often cryopreserved samples stored in liquid nitrogen can be stored for years.
What customization options are available?
Extensive customization is available. To discuss your project request a quote or email us at learnmore@sanguinebio.com.
Do you offer prospective collections?
Sanguine offers flexible prospective collection services tailored to fit your research. For more information and to request a quote, please see: our prospective biospecimen collection services page.
What is the turnaround time for custom collections?
Timelines depend on condition, sample type, and I/E criteria but we often start collection within 2 weeks of signed agreement.
Do you have samples in stock?
YES - we have in-stock inventory. You can also email us at learnmore@sanguinebio.com as we continually get new samples in our inventory.
What does unique donor mean?
Each sample from a different individual - Unique donor means each sample comes from a different person, ensuring biological diversity in your study.
Are samples collected under IRB-approved protocols?
YES - "IRB-approved collection protocols" and IRB approval documentation available upon request. Sanguine utilizes two internationally-recognized IRBs (Advarra and WCG IRB) for review and approval.
