Human Methylcellulose Complete Media Summary

Kit Summary

For the differentiation and enumeration of human hematopoietic stem cells, optimized with premium quality cytokines.

Key Benefits

  • Does not require addition of serum or cytokines
  • Optimized with premium quality recombinant proteins
  • Excellent optical clarity facilitates colony identification
  • High lot-to-lot consistency decreases variation
 

 

Why use R&D Systems Human Methylcellulose Complete Media for Colony Forming Cell Assays?

Colony forming cell (CFC) assays, which are used to enumerate and quantify multi-potent and single lineage hematopoietic progenitors, can be time consuming and laborious.

Successful growth and enumeration of cell colonies is dependent on factors such as accurate cell counts, the presence of growth factors and/or cytokines, adequate humidity, and the use of high quality media. R&D Systems offers Human Methylcellulose Complete Media, which contains all growth factors and cytokines needed to support optimal colony growth and enumeration. The Human Methylcellulose Complete Media is specially formulated and has been optimized for CFC assays using burst-forming and colony-forming erythroid (BFU-E, CFU-E), myeloid (CFU-GM, CFU-G, CFU-M), and mixed lineage (CFU-GEMM) progenitors of human origin. This product can also be used in the long-term culture-initiating cell (LTC-IC) assay.

R&D Systems Human Methylcellulose Complete Media:

  • Optical clarity facilitates colony identification.
  • High lot-to-lot consistency decreases variation.
  • Supports reproducible in vitro growth of hematopoietic stem and progenitor cells.
  • Increased cloning efficiency and improved colony growth compared to agar.
  • Does not require addition of serum or cytokines.

Human Hematopoietic Colony Formation Using the Methylcellulose-based Colony Forming Cell Assay. A. Colony forming unit-erythroid (CFU-E) are clonogenic progenitors that produce only one or two clusters with each cluster containing from 8 to approximately 100 hemoglobinized erythroblasts. It represents the more mature erythroid progenitors that have less proliferative capacity. B. Colony forming unit-granulocyte (CFU-G) are clonogenic progenitors of granulocytes that give rise to a homogeneous population of eosinophils, basophils, or neutrophils. C. Colony forming unit-granulocyte, macrophage (CFU-GM) are progenitors that give rise to colonies containing a heterogeneous population of macrophages and granulocytes. The morphology is similar to the CFU-M and CFU-G descriptions. D. Burst forming unit-erythroid (BFU-E) colonies can be described as small (3 to 8 clusters), intermediate (9 to 16 clusters), or large (more than 16 clusters) according to the number of clusters present. These are primitive erythroid progenitors that have high proliferative capacity. E. Colony forming unit-macrophage (CFU-M) are clonogenic progenitors of macrophages that give rise to a homogenous population of macrophages. F. Colony forming unit-granulocyte, erythrocyte, macrophage, megakaryocyte (CFU-GEMM) are multi-lineage progenitors that give rise to erythroid, granulocyte, macrophage and megakaryocyte lineages, as the name indicates.

Hematopoietic Stem Cells & Lineage-specific Markers

View Interactive Pathway

The definitive hematopoietic system is made up of all adult blood cell types including megakaryocytes, erythrocytes, and cells of the myeloid and lymphoid lineages. All of these cells are derived from multipotent hematopoietic stem cells (HSCs) through a succession of precursors with progressively limited potential. Hematopoietic stem cells are tissue-specific stem cells that exhibit remarkable self-renewal capacity and are responsible for the life-long mainte­nance of the hematopoietic system. HSCs are rare cells that reside in adult bone marrow where hematopoiesis is continu­ously taking place. They can also be found in cord blood, fetal liver, adult spleen, and peripheral blood. R&D Systems offers several products for studying hematopoietic lineage cells including serum-free media, lineage deple­tion antibodies and kits, and reagents for performing colony forming cell (CFC) assays.

FAQs

  1. What is the difference between the Complete (Catalog # HSC003) and Enriched (Catalog # HSC005) Methylcellulose?

    • The Complete Methylcellulose Media (Catalog # HSC003) contains four growth factors (rhSCF, rhGM-CSF, rhIL-3, and rhEPO) whereas the Enriched Media (Catalog # HSC005) contains six growth factors (rhSCF, rhGM-CSF, rhIL-3, rhEPO, rhG-CSF, and rhIL-6) for hematpoietic stem cell (HSC) differentiation.

      HSC003 is typically used with an unpurified heterogeneous population of cells. PBMCs may be mixed with HSCs and the included growth factors will stimulate the PBMCs to express other growth factors to promote differentiation of HSCs.

      HSC005 is typically used with purified HSCs and it includes growth factors to differntiate HSCs without assistance from growth factors expressed from PBMCs.

  2. What are the differences between in Methylcellulose Complete Media with EPO (Catalog # HSC003) and without EPO (Catalog # HSC004)?

    • EPO is a potent cytokine used to stimulate differentiation of HSCs. EPO is needed for erythrocyte development. Media without EPO offers researchers the ability to expand and differentiate their HSCs and then to test supplemental drugs or compounds of interest.
  3. Can the CFU assay using Methycellulose based media be performed using frozen PBMCs instead of fresh PBMCs?

    • Yes, the CFU assay can be performed using frozen PBMCs.  The PBMCs can be frozen in DMEM containing 10% FBS and 10% DMSO.
