Culture of Hematopoietic Cells

Hematopoietic stem and progenitor cells (HSPCs) can be cultured under defined conditions designed either to increase the number of primitive cells, or to promote lineage-specific expansion and differentiation into mature hematopoietic cells.

The composition and biological properties of the cells produced in different culture systems will differ considerably depending on the diverse applications for which they are intended to be used.

These may include:
Production of large numbers of long-term HSCs that mediate sustained engraftment after transplantation
Production of short-term HSCs and progenitors to rapidly restore blood counts after transplantation
Generation of large numbers of mature blood cells for infusion following acute blood loss
Identifying novel regulators of hematopoiesis
Testing the toxicity of new drug candidates
Production of HSPCs for transduction with retroviral or lentiviral vectors to correct genetic defects

Therefore, HSPC culture systems must be designed and optimized to meet the goal of the experiment, with a special focus on:
Composition and purity of the starting cell population
Choice of culture medium, cytokine combinations and concentration
Duration of the culture, medium replacement and replating schedules
The choice of assays to characterize the cells during/after culture


StemSpan™ Serum-Free Expansion Media and Supplements

STEMCELL Technologies has developed StemSpan™ Hematopoietic Cell Expansion Media and Supplements to promote the expansion of HSPCs and/or stimulate their differentiation into mature cells of specific lineages.

StemSpan™ Expansion Media include serum-free, xeno-free and animal component-free formulations. StemSpan™ Expansion Media do not contain any cytokines, allowing researchers the flexibility to prepare a medium that meets their specific requirements.
StemSpan™ Expansion Supplements are pre-mixed cocktails of recombinant human cytokines and other additives formulated either to selectively expand CD34+ stem and progenitor cells, or stimulate their differentiation into erythroblasts or megakaryocytes. Add these Supplements to StemSpan™ or any other medium for culturing hematopoietic cells.

Advantages of StemSpan™

DEFINED AND SERUM-FREE. StemSpan™ ACF is the first commercially available animal component-free medium for culturing hematopoietic stem and progenitor cells. This medium contains only recombinant and synthetic components and allows researchers to use a defined medium supplemented with stimulators of choice.
SUPERIOR PERFORMANCE. When combined with the appropriate StemSpan™ Expansion Supplement, StemSpan™ SFEM II supports greater expansion of CD34+ cells, erythroid cells and megakaryocytes than other StemSpan™ formulations or media from other suppliers.
