Liver injuries are accompanied by progenitor cell expansion that represents a heterogeneous cell population. Novel classification of this cellular compartment allows for the distinguishing of multiple subsets. The method described here illustrates the flow cytometry analysis and high purity isolation of various subsets that can be used for further assays.

The three-dimensional culture method described in this protocol recapitulates pancreas development from dispersed embryonic mouse pancreas progenitors, including their substantial expansion, differentiation and morphogenesis into a branched organ. This method is amenable to imaging, functional interference and manipulation of the niche.

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells. Gustatory receptor cells extend finger-like projections called gustatory hairs (or microvilli) into a region known as the taste pore.

Sustained fibrosis with deposition of excessive extracellular matrix proteins leads to cirrhosis. Alcohol abuse is one of the main causes of severe liver disease. We established an ethanol-induced zebrafish fibrotic liver model to study the mechanisms and strategies of promoting hepatocyte regeneration upon alcohol-induced injury.
FAQs
Fibroblast growth factors and bone morphogenetic proteins provide developmental signals that help foregut endoderm cells adopt a hepatic fate. Their activity contributes to formation of the hepatic diverticulum, which subsequently expands into the liver bud. Examining these signals helps researchers understand how positional information and intercellular communication initiate organ formation during embryonic development.
After the hepatic diverticulum forms, its progenitors expand into a liver bud through coordinated migration and proliferation. These changes increase the population of developing cells while establishing the growing liver tissue. Studying the timing and organization of expansion can reveal how early cellular movements and cell division contribute to the construction of a developing organ.
Lineage commitment directs liver bud progenitors toward hepatocyte or cholangiocyte fates. This transition links an initially developing cell population with the specialized cell types required for liver structure and function. Comparing progenitor behavior before and after commitment allows developmental biologists to investigate how specification produces distinct lineages and how altered decisions may contribute to congenital disease.
Migration positions developing cells within the emerging liver, whereas proliferation controls the size and expansion of the progenitor population. These processes must be considered together because cell number alone does not explain tissue organization. Experimental analysis of both variables helps clarify how progenitors build the liver bud and how developmental disturbances could affect organ formation.
Researchers can examine hepatic specification, formation of the hepatic diverticulum, liver bud expansion, progenitor migration, proliferation, and differentiation. Following these events in sequence helps connect early signaling with later tissue organization and lineage commitment. This developmental framework is useful for investigating how normal liver formation occurs and for identifying stages associated with congenital abnormalities.
Liver bud progenitors provide an experimental basis for constructing organoids, allowing researchers to study how developing cells self-organize into liver-like tissue. These systems can also model disease-related developmental changes and provide settings for testing tissue behavior. Their value comes from linking progenitor specification and differentiation with experimentally observable patterns of organ formation.
Because these progenitors can generate hepatocytes and cholangiocytes, they are relevant to approaches seeking to replace or restore damaged liver cells. Their study helps assess how developmental programs might inform regenerative strategies. Organoid systems derived from this biology also offer experimental platforms for examining tissue formation before potential applications in repairing injured liver tissue.
Investigating specification, migration, proliferation, and lineage commitment identifies developmental processes that may be disrupted in congenital disease. Researchers can use these processes as reference points when comparing normal and altered liver formation. Developmental models and organoid systems extend this analysis by making it possible to examine how changes in early progenitor behavior influence later tissue organization.
