Scientific Data

iPSC-derived Human Heart-forming Organoids Human iPSCs were embedded in Cultrex™ UltiMatrix RGF Basement Membrane Extract (R&D Systems, Catalog # BME001-05) and differentiated with CHIR 99021 (Tocris Bioscience, Catalog # TB4423-GMP) and IWP 2 (Tocris Bioscience, Catalog # 3533) into heart-forming organoids based on a protocol from Drakhlis, L. et al. (2021) Nat. Biotechnol. 39:737. Successful differentiation was demonstrated by staining the cells with A) a Rabbit Anti-Human Cardiac Troponin T Antigen Affinity-purified Polyclonal Antibody (green; Novus Biologicals, Catalog # NBP3-13391) to detect cardiomyocytes and a Goat Anti-Human CD31/PECAM-1 Antigen Affinity-purified Polyclonal Antibody (red; R&D Systems, Catalog # AF3628) to detect endothelial cells. The cells were counterstained with DAPI (blue; Tocris Bioscience, Catalog # 5748). As formation of early embryonic heart anlagen is associated with nascent foregut endoderm development, cells were also stained with B) a Goat Anti-Human SOX2 Antigen Affinity-purified Polyclonal Antibody (red; R&D Systems, Catalog # AF2018) and a Mouse Anti-Human HNF-4 alpha/NR2A1 Monoclonal Antibody (green; R&D Systems, Catalog # PP-K9218-00) to detect anterior and posterior foregut endoderm cells, respectively. The cells were counterstained with DAPI (blue; Tocris Bioscience, Catalog # 5748).

Current Good Manufacturing Practice (cGMP) is a harmonized set of guidelines that when implemented will ensure safe, reliable, consistent and quality-assured products. The Tocris range of cGMP small molecules is manufactured following relevant sections of ICH Q7 guidelines. Our highly skilled team has full control over the cGMP process, meaning we can ensure: a quality-assured manufacturing system, batch-to-batch consistency, consistent supply, traceability from starting material to final product, and animal-free production.
