Here we present a protocol that generates large amounts of murine monocytes from heterogeneous bone marrow for translational applications. In comparison to others, this new method helps reduce the number of sacrificed animals and lowers costs by avoiding expensive methods such as high gradient magnetic cell separation (MACS).

This video describes the technique of aspirating bone marrow from iliac spine and smear preparation for biopsy. In the example, we perform bone marrow aspiration from an acute myeloid leukemia (AML) patient and examine the cells to check for measurable residual disease (MRD), an important prognostic biomarker.

Here we describe an optimized, highly reproducible protocol to isolate Mesodermal Progenitor Cells (MPCs) from human bone marrow (hBM). MPCs were characterized by flow cytometry and nestin expression. They showed the ability to give rise to exponentially growing MSC-like cell cultures while retaining their angiogenic potential.
FAQs
During flushing, buffered medium dislodges marrow from bone cavities; mechanical dissociation instead breaks up the marrow material directly. Both approaches create a cell suspension for later filtration, while centrifugation or density-gradient separation can provide additional enrichment. This distinction matters when preparing material for analyses or cultures that require separated marrow cell populations.
Filtration removes larger debris from the marrow suspension, producing a cleaner cell preparation. Centrifugation or density-gradient separation can then enrich desired populations rather than leaving all recovered material together. These processing stages help align the isolated sample with downstream uses such as flow cytometry, cell culture, transplantation, or molecular analysis.
The method provides access to both hematopoietic cells, relevant to blood formation and immunity, and stromal cells, relevant to skeletal biology and bone regeneration. Recovering these populations makes the preparation useful for examining biological processes across blood, immune, and skeletal systems rather than focusing on a single tissue function.
A typical sequence begins with removing bone-associated tissue, followed by flushing or mechanically dissociating marrow in buffered medium. The resulting suspension is filtered to remove debris. If a more selected population is needed, centrifugation or density-gradient separation can provide additional enrichment before the sample enters a downstream assay or culture.
The recovered cells can support flow cytometry, cell culture, transplantation, and molecular analysis. They may therefore be incorporated into studies that examine marrow-derived material through different experimental formats. This flexibility is important because the same isolation workflow can provide starting material for cellular, transplantation-focused, and molecular investigations within biology.
These preparations support disease modeling in leukemia and studies of immune responses, bone regeneration, and the effects of drugs or environmental stressors. Their value lies in providing experimentally accessible marrow-derived material for comparing biological responses across these contexts. The resulting data can connect marrow cell behavior with blood, immune, skeletal, or exposure-related questions.
