STUDY EVIDENCE

Lung and kidney organoids for safety studies

Normal-lung studies connect alveolar- and airway-associated phenotypes with an LPS injury comparison, while kidney organoid studies combine identity profiling with serial morphology after doxorubicin exposure. New candidate studies can match model provenance, exposure conditions and assay endpoints to each organ.

Normal lung: identity and LPS injury4 study figures
01Normal lung | alveolar
Alveolar organoid morphology and ATII-associated LysoTracker signal

Alveolar organoid morphology and ATII-associated LysoTracker signal

Bright-field, DAPI, LysoTracker and merged views show alveolar organoid morphology and ATII-associated acidic-organelle signal.

Supports selection of alveolar-associated phenotype and injury endpoints
02Normal lung | airway
SCGB1A1 (CC10) and KRT5 airway-cell signals

SCGB1A1 (CC10) and KRT5 airway-cell signals

Immunofluorescence shows club- and basal-cell profiles that help distinguish alveolar- and airway-focused study directions.

Helps determine whether alveolar- or airway-focused endpoints are more relevant to the candidate
03Normal lung | LPS injury window
Serial morphology under control and LPS conditions

Serial morphology under control and LPS conditions

Bright-field views on days 1, 5 and 7 guide post-treatment observation timing and follow-on quantitative endpoints.

Supports selection of the observation window for pulmonary-injury studies
04Normal lung | alveolar endpoints
AT1/AT2 profiling under normal and LPS conditions

AT1/AT2 profiling under normal and LPS conditions

Bright-field, AT1, AT2, DAPI and merged views connect the injury condition with alveolar-cell profiling.

Supports selection of alveolar-cell injury endpoints

Whole-organoid and local kidney structures

Whole-organoid and local kidney structures

Bright-field and inset views provide structural context for subsequent identity and injury assays.

06Normal kidney | nephron identity
Nephrin- and LTL-associated immunofluorescence

Nephrin- and LTL-associated immunofluorescence

Nephrin- and LTL-associated signals provide podocyte- and tubule-related context for selecting cell-type-relevant endpoints.

Supports selection of organ- and cell-type-relevant safety endpoints

Morphology before and 24/48 hours after doxorubicin exposure

Bright-field imaging before exposure and at 24/48 hours shows the time course of morphological change and guides downstream sampling and assay timing, including alignment of the kidney observation window in a two-organ study.

Supports selection of kidney-injury observation and sampling times

INTERPRETATION

Plan safety studies around target organs and endpoints

How the results are used

Select a lung, kidney or dual-organ strategy with safety endpoints matched to the candidate's risk profile.

Study application

The lung and kidney studies provide organ-specific model identity, injury endpoints and observation windows. For the same candidate, our scientists can design complementary studies with dose, timing and controls tailored to each organ, helping your team assess risk signals across organs.

Follow-on study

Set exposure gradients and recovery studies around the candidate mechanism, with organ-specific molecular endpoints and batch replication.
