A three-dimensional clonogenic assay that allows pancreatic-like progenitors to differentiate into insulin-expressing colonies is described. This method takes advantage of semi-solid media containing methylcellulose, Matrigel and growth factors, in which single progenitors proliferate and differentiate in vitro, permitting quantification of the number of functional progenitors in a population.

ScanLag is a high-throughput method for measuring the delay in growth, namely lag time, as well as the growth rate of colonies for thousands of cells in parallel. Screening using ScanLag enables the discrimination between long lag-time and slow growth at the level of a single variant.
FAQs
Changes in colony diameter can reflect population expansion as cells divide and spread across a solid culture medium. The measured width therefore provides a practical way to follow growth under defined conditions. Interpreting the measurement requires considering incubation time, nutrient availability, temperature, and other environmental conditions, because each can influence the observed size.
Incubation time affects how long cells have to divide and spread across the culture surface. A measurement taken earlier may not represent the same stage of growth as one taken later. Consequently, comparisons are most meaningful when measurements account for incubation time, especially when researchers evaluate growth differences among strains or experimental conditions.
When microbial strains grow under comparable culture conditions, differences in colony diameter can provide a basis for characterizing their growth behavior. Such comparisons help researchers examine variation in microbial physiology and population expansion. Nutrient availability, temperature, incubation time, and other environmental factors should remain considered because they may also contribute to differences in the measured width.
A basic assessment begins by growing microorganisms together on a solid culture medium and allowing visible colonies to develop under the selected conditions. Researchers then measure the width of the colony and compare that value across strains, incubation times, environmental conditions, or treatments. This workflow supports standardized analysis of growth in culture-based experiments.
In antibiotic-response experiments, researchers compare colony diameter between cultures exposed to the treatment and cultures examined under a comparison condition. Differences in measured width can indicate that the microorganisms responded differently during growth. The approach allows treatment effects to be assessed alongside factors such as incubation time, temperature, and nutrient availability.
Colony-diameter measurements can contribute to analyses of microbial physiology, environmental influences, and experimental outcomes. By comparing widths across controlled conditions, researchers can examine how microorganisms grow and how their growth differs among strains or treatments. This makes the measurement useful in culture-based biology studies that require a practical, standardized indicator of growth.
