Description

StemBeads® FGF2 is a patented growth factor supplement that offers a novel way to culture cells with native Fibroblast Growth Factor 2 more efficiently. FGF2 is key for growth of human induced pluripotent stem cells (iPSCs), fibroblast cells, wound healing cells such as macrophages, cancer cells, and neural progenitor cells (NPCs). StemBeads® FGF2 are microbeads composed of an FDA approved, biodegradable PLGA polymer that is loaded with native recombinant human FGF2. Controlled delivery and stable levels overcome the 4.5 hour half-life (Figure above) of FGF2 and improve cell cultures while saving researchers valuable time and resources.

StemBeads® FGF2 have been tested in media such as mTeSR, mTeSR plus, Stemflex, Flex 8, Nutristem, 10% FBS, and neuronal medium including neural progenitor expansion medium (NPEM) with enhanced cellular profiles. StemBeads® FGF2 can be combined with other StemBeads® varieties.

Sustained Release Protein Cell Culture

StemBeads are a revolutionary controlled-release growth factor technology. The StemBeads product is currently used for improved cell culture in more than 100 scientific laboratories globally. StemBeads technology encapsulates a growth factor in a PLGA hydrogel that stabilizes the protein and releases it steadily over several days. With growth factor levels stabilized, spontaneous differentiation is reduced, pluripotency is increased, and feeding schedules are reduced to only 2-3 times per week.

StemBeads are added to your medium to achieve a desired growth factor release, sustained over several days. Following, the beads are washed from the culture, the medium is replaced, and the process repeated as required.
