GLOSSARY

# DeepInsight® Glossary

Plain-language definitions for the cell line development and cellular imaging terms used across the DeepInsight platform.

## Terms

## Cell Line Development (CLD)

The process of generating and selecting stable, high-producing cell lines for biologics manufacturing.

## CHO cells

Chinese hamster ovary cells, a mammalian host cell line widely used to produce therapeutic proteins.

## HEK cells

Human embryonic kidney cells, a mammalian cell line used in research and biologics production.

## Brightfield imaging

Optical microscopy using transmitted white light, without fluorescence or specialised contrast labels.

## Label-free cell counting

Counting cells directly from unlabelled images, avoiding stains or fluorescent markers.

## Clone

A population of cells derived from a single parent cell, tracked through expansion and selection.

## Clone ranking

Ordering candidate clones by predicted performance using growth, recovery, and other measured features.

## Recovery rate

How quickly a clone resumes growth after seeding or transfer.

## Growth prediction

Forecasting later population growth from early imaging timepoints.

## Neural fingerprinting

A learned optical signature for each cell or clone, used to cluster phenotypes and identify stable candidates.
