Bone Marrow Products

For Your Cell-Based Assays

Human bone marrow (BM) is a rich source of human primary cells, including hematopoietic stem and progenitor cells (HSPCs), mononuclear cells (MNCs), as well as mesenchymal stromal cells (MSCs), also referred to as stromal cells or mesenchymal stem cells. Human primary cells isolated directly from BM retain key aspects of the tissue of origin, reflecting the donor in vivo microenvironment more accurately than cell lines. Consequently, this higher physiological relevance makes them a more attractive starting point for research areas such as regenerative medicine and cell therapy.

Why Choose Human Bone Marrow Products from STEMCELL Technologies?

STEMCELL offers a comprehensive collection of ethically sourced fresh or cryopreserved BM primary cell products to support your research needs.* Ensure continuity in your research and start experiments according to your schedule with a reliable supply of high-quality, donor-specific primary cells that are ready to use upon receipt, with guaranteed viability and purity documented in the lot-specific Certificate of Analysis (CoA).

Learn more about how we can work closely with you as your primary cells supplier.

Why Use Human Primary Cells from STEMCELL Technologies?

  • Choose cells that are more physiologically representative of cells in vivo.
  • Access donor samples collected using regulatory authority-approved consent forms and protocols.
  • Request custom products for non-standard cell types or collections with specific requirements.
  • Reserve large numbers of cryopreserved cells and start experiments on your schedule with cells you've already tested.
  • Reduce time spent collecting and culturing primary cells.

We offer a range of specialized cell culture media and supplements for HSPC expansion and differentiation, as well as for the detection of hematopoietic cells in functional assays. Find out more below:


Whether you’re working with healthy or diseased HSPCs, StemSpan™ serum-free media allow for cell expansion or lineage-specific differentiation.

When added to StemSpan™ media, StemSpan™ expansion supplements selectively promote the expansion of CD34+ cells or stimulate their differentiation into erythroid, myeloid (granulocyte or monocyte), or megakaryocyte progenitor cells. Complete kits, consisting of medium, supplements, and substrates, can be used to generate T cells or NK cells from CD34+ cells.

cGMP StemSpan™-AOF is free of animal-derived components, containing only recombinant proteins and synthetic components. This media product is manufactured and tested following relevant cGMPs under a certified quality management system.

Promote optimal growth and differentiation of hematopoietic progenitor cells in culture with MethoCult™. These media are the “Gold Standard” for the in vitro detection and quantification of hematopoietic progenitor cells in the colony-forming unit (CFU) or colony-forming cell (CFC) assay (also known as the methylcellulose assay). Formulations are available for human, mouse, and rat cells.

For an alternative to methylcellulose-based media for CFU assays, choose MegaCult™ medium in combination with collagen gels. These gels can be readily dehydrated for subsequent cytochemical or immunocytochemical staining. MegaCult™ is designed specifically for megakaryocyte progenitors (CFU-Mk) from human hematopoietic tissues.

Achieve long-term culture of hematopoietic progenitor cells with adherent MSCs using MyeloCult™ media. An important application of MyeloCult™ is the quantification of primitive hematopoietic progenitor cells in the long-term culture-initiating cell (LTC-IC) assay.
