Figures

Figure 1

Mouse ES cells (HM1) were differentiated into embryoid bodies (EBs). At day 5 EBs were dissociated with the Embryoid Body Dissociation Kit (# 130-096-348) and CD309 expressing cells were isolated using the CD309 (Flk-1) MicroBead Kit, an LS Column, and a MidiMACS™ Separator. After fluorescent labeling with Labeling Check Reagent‑APC (# 130-095-237) cells were analyzed by flow cytometry using the MACSQuant

^®

Analyzer. Cell debris and dead cells were excluded from the analysis based on scatter signals and propidium iodide fluorescence.

Improved endothelial differentiation of isolated CD309 (Flk-1)⁺ cells:

Unseparated or CD309-enriched cardiovascular progenitor cells (derived as in fig. 1) were subjected to endothelial differentiation in the presence of 50 ng/mL VEGF. Differentiation efficiency was evaluated by immunofluorescence using CD31-FITC (green) and DAPI counterstain (blue).

Detailed product information

Background information

CD309 is a class 3 receptor tyrosine kinase, also known as Flk-1 (fetal liver kinase 1), vascular endothelial growth factor receptor 2 (VEGFR2), or kinase insert domain receptor (KDR). CD309 is one of the earliest differentiation markers for endothelial and hematopoietic cells.

^1,2

Using mouse embryonic stem cells it has been shown that CD309 is a marker for multipotent cardiovascular progenitor cells that give rise to cardiomyocyte, endothelial, and vascular smooth muscle cell lineages.

^3,4

Note

: For optimal flow cytometric analysis of isolated cells after separation we recommend Labeling Check Reagent.
