STEMdiff™ Dorsal Forebrain Organoid Differentiation Kit

Cell culture medium kit for robust generation of dorsal forebrain neural organoids from human pluripotent stem cells
概要
Robustly generate three-dimensional, patterned brain organoid cultures from human pluripotent stem cells without matrix embedding. STEMdiff™ Dorsal and Ventral Forebrain Organoid Differentiation Kits are serum-free cell culture media that work with AggreWell™-generated embryoid bodies to prevent organoid fusion and enable the scalable generation of over 500 highly reproducible organoids per kit. Adapted from protocols by Sergiu Paşca (F Birey et al. Nature, 2017), these brain-region-specific organoids are three-dimensional in vitro models with a cellular composition and structural organization that is representative of the developing human forebrain. STEMdiff™ Dorsal Forebrain Organoid Differentiation Kit (Catalog #08620) generates tissue of the early developing dorsal pallium, while STEMdiff™ Ventral Forebrain Organoid Differentiation Kit (Catalog #08630) generates tissue of the early developing ventral subpallium. Organoids generated with these kits can also be co-cultured as assembloids to study brain region interactions (F Birey et al. Nature, 2017). For extended periods of organoid culture (> 50 days), the components required for organoid maintenance are available as STEMdiff™ Neural Organoid Maintenance Kit (Catalog #100-0120).
Advantages
⦁ Reduce handling and media waste with fusion-free growth media
⦁ Obtain greater analytic sensitivity for disease phenotypes with reproducible morphology between lines and individual organoids
⦁ Generate over 500 organoids per kit using AggreWell™800 for higher-powered statistical replicates and more detailed longitudinal study
⦁ Eliminate matrix embedding steps with the matrix-free formulation and protocol
⦁ Easily process and section consistently sized organoids
⦁ Achieve long-term culture survival and reduced caspase-3 expression for neurotoxicity and neurodegenerative models
⦁ Combine modular region-patterned organoids to generate advanced assembloids for disease modeling and regenerative applications

Schematic protocol diagram to generate patterned dorsal forebrain organoids from iPSCs

Figure 1. Schematic for the STEMdiff™ Dorsal Forebrain Organoid Differentiation Kit

Human ES or iPS cell-derived dorsal forebrain organoids can be generated in 43 days. Embryoid bodies can be created in 6 days with AggreWell™800 plates. The EBs are then cultured in suspension, allowing growth and subsequent patterning to the dorsal forebrain. For the long-term maintenance and further maturation of dorsal forebrain organoids, see the PIS.

GFP-labeled ventral forebrain organoids were co-cultured and fused with unlabeled dorsal forebrain organoids for one week prior to live imaging in Forebrain Organoid Differentiation Medium from STEMdiff™ Dorsal Forebrain Organoid Differentiation Kit (right) or BrainPhys™ Imaging Optimized Medium (BPI, left). Interneuron migration can be visualized more clearly in BPI. Adapted from Zabolocki et al. 2020, Nature Communications, available under a Creative Commons 4.0 License.
