Growth factors and cytokines are important signaling molecules that participate in regulating embryonic development, tissue repair, and cellular communication. There are a number of growth factors identified to be crucial for stem cell survival, self-renewal, differentiation, and de-differentiation. Stem cell culture relies heavily on specific growth factor combinations that modulate signaling pathways to sustain stem cell self-renewal states and/or to induce lineage specific differentiations. abm offers high-quality growth factors and cytokines for targeted differentiation of iPSCs. These proteins are extensively tested to ensure high biological activity, high purity, freeze-thaw stability, and structural homogeneity. Our growth factors and cytokines allow you to perform reproducible results in all your stem cell projects without any interference from other protein contaminants.
