Human Methylcellulose Serum-Free Base Media

产品介绍

Product Details

Kit Summary

For the growth and differentiation of human hematopoietic stem cells.

Key Benefits

ØCan be supplemented with user-defined cytokines and growth factors

ØExcellent optical clarity facilitates colony identification

ØHigh lot-to-lot consistency decreases variation

Why is it Important to Verify Hematopoietic Progenitor Cell Identity using Established Markers?

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.  

Components

Ø90 mL of Human Methylcellulose Base Media and 15 mL of Cell Resuspension Solution.  

Data Examples

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.

Complete Human Methylcellulose Media

*Base media and stock solutions do not contain cytokines and will not support colony growth unless conditioned media, cytokines, or other culture supplements are added.

Preparation and Storage

ØStability & Storage

ØStore the unopened product at -20 to -70 °C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Do not use past expiration date.

Background: Mesenchymal Stem Cells

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.
