Human induced pluripotent stem cells (iPSCs) are an in vitro model that represent a pivotal breakthrough in regenerative medicine and cellular biology. Reprogramming iPSCs grants these cells the ability to differentiate into any cell type of the three germ layers: ectoderm, mesoderm, and endoderm. This provides unparalleled potential for disease modeling, drug discovery, and cell-based therapies, all without the ethical concerns associated with using embryonic stem cells.

Differentiation of induced pluripotent stem cells (iPSCs) into neuroectoderm

Differentiating iPSCs into ectoderm lineage is particularly significant, given the ectoderm’s role in generating the central and peripheral nervous systems, sensory organs, and skin. Differentiating iPSCs into neuroectodermal cells, followed by further differentiating into ectodermal lineages, is critical for studying neurodevelopmental processes, modeling neurological disorders, and developing potential therapies for conditions impacting the nervous system and skin.

In this application note, we outline the method for differentiating iPSCs into neuroectoderm cells using media containing members of our recombinant FGF-2 family, such Qkine FGF2-G3 (Qk053), together with noggin (Qk034).

Differentiation of induced pluripotent stem cells (iPSCs) into mesoderm

Differentiating iPSCs into mesoderm linage of cells is particularly significant, given the mesoderm’s role in generating a wide range of vital tissues and organs, including the heart, blood, muscles, and bones. This provides unparalleled potential for disease modeling, drug discovery, and cell-based therapies.

In this application note, we outline the method for differentiating iPSCs into mesoderm cells using media containing members of our recombinant FGF-2 family, such as Qkine FGF2-G3 (Qk053), along with both activin A (Qk001), and BMP-4 (Qk038) growth factors.

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 organoids for research and transplantation purposes.

In this application note, we outline the method for differentiating iPSCs into definitive endoderm cells using media containing members of our recombinant FGF-2 family, such Qkine FGF2-G3 (Qk053), along with both activin A (Qk001), and BMP-4 (Qk038) growth factors.

Weekend-free human induced pluripotent stem cell culture using thermostable FGF-2 (bFGF) and animal origin-free TGF-β1 and vitronectin for improved colony homogeneity

In this application note, we describe the method for maintaining, growing, and testing the pluripotency of iPSC using E8-like media containing Qkine FGF2-G3 (Qk053) and TGF-β1 PLUS (Qk010) growth factors and using Qkine vitronectin (Qk120) as the extracellular matrix for cell attachment. This process showcases the maintenance, expansion, and pluripotency evaluation of iPSC without the need for daily feeding, enabling weekend-free maintenance and expansion while preserving the cells’ pluripotency and proliferative potential.

Animal origin-free BDNF and GDNF neural growth factors for enhanced iPSC-derived neuronal cultures

This collaborative study compares BDNF (Qk050) and GDNF (Qk051) from Qkine and R&D Systems in their ability to support the differentiation and maintenance of iPSC-derived motor neurons.

Maintenance of iNeurons using Qkine animal origin-free BDNF

It is essential to use high-quality and biologically active recombinant proteins to maintain the neural phenotype of iNeurons. This application note reports on the use of high purity, animal origin-free BDNF (Qk050) for the maintenance of iNeurons.

Differentiation of induced pluripotent stem cells (iPSCs) into dopaminergic neurons

Differentiation of induced pluripotent stem cells (iPSCs) into dopaminergic neurons requires specific conditions to obtain the desired cell type. This application note describes the method we use to differentiate human iPSCs into functional dopaminergic neurons, using a variety of media types that utilize a series of Qkine growth factors; FGF8a (Qk059), BDNF (Qk050), GDNF (Qk051)  and TGFb3 (Qk054) at different stages of key differentiation steps.

Species-specific and optimized growth factors for the production of bovine and porcine cultivated meat and fat

Cellular agriculture has the potential to transform food production and impact the health and well-being of future generations. This application note discusses growth factors required for cultivated meat, fish and dairy and the need for species-specificity and quality, with a particular focus on FGF-2, TGFβ3 and HGF.
