Qkine is a company run by scientists, and the science is the focus of everything we do.Our theme at ISSCR this year was stress-free stem cell culture - exploring how suppliers of recombinant proteins can proactively improve the quality, availability and functionality of growth factors to generate experimental outcomes faster, easier and more efficiently.We discussed priorities for the stem cell science supply chain with scientists from academic and industry labs and had in-depth conversations about the impact of growth factors and cytokines quality on reproducibility and how to integrate new technologies, such as controlled-release and thermostable proteins, to improve the scalability of expansion and differentiation protocols.Through collaboration, we learn and, together, improve the future of stem cell research.
