Astrocytes Differentiation Service


iPSC Astrocytes Differentiation

Drug Discovery

CNS disease modeling

Astrocytes, the most abundant glial cells found in the central nervous system and spinal cord, play a critical role in neuronal development, neuronal metabolism, neurotransmitter synthesis, and synaptic function as well as repair and neurogenesis during CNS and spinal cord injury. Astrocyte dysfunction has been implicated in neurological disorders such as Parkinson’s disease, Alzheimer’s disease, Amyotrophic lateral sclerosis, and Huntington’s disease. iPSC-derived astrocytes provide a readily sourced, consistent, and biologically relevant alternative to primary astrocytes for the study of synaptic transmission and plasticity in normal CNS function and disease progression.

Human iPSC-derived astrocytes are powerful in vitro tools for developing physiologically relevant models of human CNS and diseases. These iPSC-derived astrocytes recapitulate the morphological and functional properties of primary cells with the advantages of cell culture. Applied StemCell provides custom service to differentiate your iPSCs into ready-to-use, high-purity astrocytes:

Astrocytes
Biomarkers GFAP
S100beta
Other markers available upon request

Optional! Cell Line validation and drug screening services are available.

  • Benefits and advantages of iPSC differentiation to neurons and glial cells:

    • iPSC-derived neurons and glial cells are genetic and physiologically relevant in vitro models to study neural development and associated disorders: congenital disorders, neurodegenerative disorders and brain tumors.
    • Avoid genetic variability; generate isogenic neurons and glial cells in cell culture formats that are reproducible and scalable
    • Generates a valuable model for identifying new targets for neuro-regeneration as opposed to treatments limiting to symptomatic relief or delaying disease progression.
    • Allows for future adaptation of technology for regenerative medicine and cell therapy in humans for the treatment of Parkinson’s disease, Lou-Gehrig disease (ALS), Huntington’s disease, and spinal cord injury among other diseases.
    • Differentiation of genome engineered in iPSCs (mutation introduction or correction) to neurons, offers an isogenic source of control-disease cell lines for basic research, drug development, hard-to-model neurological disorders, and potentially for gene therapy. 

    Applications:

    • Co-culture with neurons for advanced, in vivo-like cell line models
    • Neurotoxicity screening
    • Disease modeling
    • High throughput drug discovery and drug screening applications
    • Drug neurotoxicity screening applications

Frequently Asked Questions

  • The astrocytes that will be provided for your custom project will be cryopreserved, mature astrocytes.

  • We will provide 100 mL of astrocyte maintenance media with your custom differentiated astrocytes and protocol for thawing and maintenance of your astrocytes.

  • No, we don’t characterize for staining during astrocyte precursor stage. We characterize mature astrocytes using immunohistochemical analysis: positive staining for GFAP and S100beta and negative for Tuj1.

  • Astrocyte precursor cells are intermediate stage cells that are not stable and once thawed, cannot be maintained or passaged at this stage without maturation.
