Unlocking Insights with Lesion-induced Cellular Models

  • Our lesion-induced cellular models involve the precise creation of cellular damage within cultured systems, enabling the study of disease progression, repair mechanisms, and therapeutic responses.
  • We simulate critical pathological conditions, including neuroinflammation, excitotoxicity, and neurotoxicity, by applying specific proteins or chemical compounds meticulously selected to replicate key disease features.
  • We offer customizable model designs and experimental protocols to meet very specific research needs.

Available Lesion-induced Models at Creative Biolabs

Below, we detail our expertise in modeling key neurological disorders, including induction methods, available cells, and cutting-edge detection strategies. These models enable the evaluation of potential therapeutics and customization of assays for specific research needs.

Alzheimer's Disease (AD): Mimicking Aβ and Tau Pathology

  • Induction methods:
    • Aβ1-42 exposure: Neurons are exposed to Aβ1-42, inducing neurotoxicity, synaptic dysfunction, and tau hyperphosphorylation.
    • Tau Seed Incubation: Recombinant tau proteins, including wild-type and disease-associated mutants (e.g., P301L), are introduced to cells to initiate tau seeding and aggregation.
  • Available cells: Primary cortical/hippocampal neurons, SH-SY5Y cell line, HT22 cell line, iPSC-derived neurons.
  • Assays: Toxic Amyloid-beta Peptide 1-42 Exposure Assay, Tau Uptake & Seeding Assay

Parkinson's Disease (PD): Modeling Dopaminergic Neuron Degeneration

  • Induction Methods:
    • 6-OHDA: 6-hydroxydopamine (6-OHDA) is applied to induce selective dopaminergic neuron degeneration via oxidative stress. We optimize 6-OHDA concentrations and exposure times to generate reproducible lesions.
    • MPP+: 1-methyl-4-phenylpyridinium (MPP+) is used to inhibit mitochondrial complex I, leading to mitochondrial dysfunction and oxidative stress. We monitor mitochondrial respiration and oxidative stress markers to validate the model.
    • Rotenone: Rotenone induces α-synuclein aggregation and mitochondrial dysfunction. We utilize precisely measured rotenone concentrations and durations of exposure for optimal effect.
  • Available cells: Primary cortical/hippocampal/mesencephalic neurons, SH-SY5Y cell line, iPSC-derived neurons.
  • Assays: Cell Viability Assay, α-Synuclein Aggregation Analysis, Neuronal Mitophagy Detection Assay

Amyotrophic Lateral Sclerosis (ALS): Modeling Motor Neuron Lesions

  • Induction Methods:
    • Sodium arsenite: Acute sodium arsenite exposure triggers stress granule (SG) formation and TDP-43 recruitment in TDP-43-overexpressing cells.
    • L-glutamate: L-glutamate induces excitotoxicity and neuronal cell death, mimicking the glutamate-mediated neurodegeneration observed in ALS.
  • Available cells: Primary cortical neurons, NSC-34 cell line, SH-SY5Y cell line, TDP-43 overexpress cell line, iPSC-derived neurons.
  • Assays: TDP-43 Aggregation Assay, Neurotoxicity Assay

Epilepsy: Modeling Neuronal Hyperexcitability and Seizure Pathways

  • Induction Methods:
    • Kainic Acid/4-AP Exposure: This method activates glutamate receptors, generating synchronized neuronal firing within hippocampal or cortical cultures, thus replicating a temporal lobe epilepsy condition.
    • Low-Mg²⁺ or High-K⁺ Medium: This procedure interrupts ion homeostasis to produce spontaneous epileptiform activity inside of neuronal networks.
  • Available cells: Primary hippocampal/cortical neurons, iPSC-derived glutamatergic/GABAergic neurons, Ion channel overexpression cell line
  • Assays: Microelectrode Array (MEA) Assay, Calcium Imaging Assay

Multiple Sclerosis (MS): Simulating Demyelination and Neuroinflammation

  • Induction Methods:
    • Lysophosphatidylcholine (LPC) or Cuprizone Exposure: This method introduces oligodendrocyte apoptosis and demyelination in co-cultures comprised of neurons and oligodendrocytes.
    • Cytokine Cocktails: IL-1β, TNF-α, and IFN-γ treatment, which activates microglia and astrocytes, replicating neuroinflammatory microenvironments.
  • Available Cells: Primary neuron-oligodendrocyte co-cultures, iPSC-derived oligodendrocytes and microglia, Human astrocyte-microglia co-culture systems
  • Assays: Cytokine Release Assay, LPS induced Neuroinflammation Assay, Myelination, Demyelination & Remyelination Assay
