Organoid Models

We develop and apply physiologically relevant human organoid systems for disease modeling, therapeutic testing, and mechanistic studies.

Organoids are advanced three-dimensional (3D) models that mimic the structure and function of human organs. Derived from stem cells, organoids self-organize into complex tissues that closely resemble key features of their in vivo counterparts. By recapitulating aspects of human organ development, physiology, and disease, organoids provide insights that are often difficult to obtain using traditional two-dimensional (2D) cell cultures or animal models. As highly relevant preclinical models, organoids have broad applications in disease modelling, drug discovery and screening, biomarker identification, and predicting patient-specific responses to therapy.

Why Nocteva Organoids

Our Organoid Platform

Key Advantages of Our Organoid Platform

Human-relevant biology
Organoids derived from human iPSCs capture key aspects of human tissue architecture, physiology, and disease.
High reproducibility
Standardized protocols and rigorous quality control ensure consistent organoid generation across batches and studies.
Disease-specific models
Patient-derived organoids enable the study of disease mechanisms and therapeutic responses in a clinically relevant context.
Reliable preclinical platform
More predictive, human-specific data than conventional 2D cultures, complementing or reducing reliance on animal models.
Scalable & assay-ready
Uniform organoids suitable for drug screening, target validation, biomarker discovery, and efficacy testing.
Translational value
Data that support preclinical decision-making and accelerate the path toward clinical development.
Reproducibility & Maturity

Reproducible and rapidly maturing, batch after batch

Our protocols deliver markedly lower batch-to-batch variation than competitors, while reaching human-relevant developmental maturity far faster, for predictable, dependable data.

Batch reproducibility (MDS)
Each dot is one organoid batch. Nocteva's batches cluster tightly (highly reproducible), while the competitor's scatter widely.

How closely our organoids mirror the human organ

Our retinal organoid model illustrates the level of biological complexity and characterization achieved across our platform. It contains all major retinal cell types organized in their native layered architecture, confirmed by brightfield and immunofluorescence imaging. Every model system below is characterized with the same level of depth and rigor.

Brain Organoids

Brain organoids are iPSC-derived models in which multiple neural cell types self-organize into tissue-like structures, making it possible to study cellular interactions and region-specific biology in a human in vitro system.
