💡Application Note: Differentiation of induced pluripotent stem cells (iPSCs) into neuroectoderm

The differentiation of feeder-free human induced pluripotent stem cells (iPSCs) into neuroectodermal cells is a complex process that uses growth factors such as noggin and FGF-2.

Additionally, factors such as activin receptor-like kinase receptor blocker SB431542 are required to improve the efficiency of differentiation and stabilize the neuroectodermal fate.

This application note outlines the method for differentiating iPSCs into ectoderm cells using:

We looking forward to supporting the Human Development: Stem Cells, Models, Embryos meeting at the University of Warwick on the 7-9 September.

Development has been organizing regular meetings on human development for over a decade. For 2026, the journal has teamed up with the Wellcome-funded consortium the Human Developmental Biology Initiative (HDBI) to co-organize this event, which will bring together researchers from around the world, united by an interest in understanding human developmental biology. Topics covered will range from lineage specification, patterning and morphogenesis through to bioengineering and disease modelling.

If you're attending come along and speak to our team, Gallant and Stewart would love to meet you and explain how Qkine high purity and bioactivity growth factors can enhance your developmental research.

After a nice calm summer it's time for the Qkine team to head back out into the world!

🌍On the 3rd September our Senior Product Manager Stewart will be lending her services as the Commercial Dragon in the session 'The Impact Factor: Turning an Idea into Action' at the first Human Specific Research Community North meeting > https://zurl.co/KGOhi

🌍 We'll then be exhibiting at the Human Development: Stem Cells, Models, Embryos meeting at the University of Warwick , 7-9th September > https://zurl.co/eTXoL

🌍 A trip across the pond then takes us to Seattle our first COMMONS meeting as members and , Inc. PluriCon meeting on the 17 September > https://zurl.co/Yyu4f

🌍 Our Commercial Director Rob Nixon is heading in the opposite direction for ODC26 Seoul, 17-18 September to connect with scientists in South Korea > https://zurl.co/hvhsf

🌍 Towards the end of the month we'll be staying local at the Gastruloids & Embryoids Workshop 2026 at the University of Cambridge , 21-22 September.

💡Application Note: Differentiation of induced pluripotent stem cells (iPSCs) into mesoderm

The differentiation of feeder-free human induced pluripotent stem cells (iPSCs) into mesodermal cells is a complex process that uses growth factors such as activin A, BMP-4, and FGF-2.

Additionally, factors such as CHIR99021 and the phosphatidylinositol 3-kinase (PI3-kinase) inhibitor LY294002 are required to improve the efficiency of differentiation and stabilize the mesodermal fate.

This application note outlines the method for differentiating iPSCs into mesoderm cells using:

🌟New product

HiDef® ITS is a defined formulation designed for the routine maintenance and low-density attachment of adherent cells under reduced serum conditions.

HiDef® ITS is a combination of insulin (to stimulate glucose uptake), transferrin (to facilitate iron transport), and sodium selenite (a potent antioxidant and common component supplied by serum), previously shown to reduce the amount of FBS needed in the culture of a wide range of cell types, including primary cells, immortalized cell lines, and stem cells.

💡Application Note: Differentiation of induced pluripotent stem cells (iPSCs) into endoderm

Differentiating iPSCs into endodermal linage cells is particularly important due to the critical roles endodermal derivatives play in human physiology.

Understanding the differentiation process of iPSCs into endodermal cells offers promise for developing treatments for a variety of conditions, including liver diseases, diabetes, and cystic fibrosis, as well as for generating for research and transplantation purposes.

This application note outlines the method for differentiating iPSCs into definitive endoderm cells using:

Uniquely animal origin-free activin AB heterodimer!

Activins are members of the transforming growth factor-beta (TGF-β) superfamily, a group of proteins that play key roles in regulating cell growth, survival and differentiation. In vivo activins exist as homodimers or heterodimers, the activin heterodimer AB is widely expressed and biologically active with similar functions to the activin AA homodimer.

Qkine recombinant activin AB is a bioactive 25.7 kDa heterodimer, animal origin-free, tag free and carrier free for improved reproducibility.

🌟New product

HiDef® N-2 is a defined formulation designed for the culture and growth of neurons, neural progenitor cells (NPCs), stem cells, and neuroblastoma (NB) cells, among other cell types, as well as differentiation of embryonic and induced pluripotent stem cells in neural and pancreatic lineages.

N-2 has been historically shown to improve survival and expression of neuronal cells, including neurons in primary culture, and serves as an effective substitute for the N-1 Bottenstein formulation.
