Cells are the building blocks of life, present in every living organism. But how similar do you think your cells are to a mouse? A fish? A worm.

Comparing cell types in different species across the tree of life can help biologists understand how cell types arose and how they have adapted to the functional needs of different life forms. This has been of increasing interest to evolutionary biologists in recent years because new technology now allows sequencing and identifying all cells throughout whole organisms. “There’s essentially a wave in the scientific community to classify all types of cells in a wide variety of different organisms,” explained Bo Wang, an assistant professor of bioengineering at Stanford University.

In response to this opportunity, Wang’s lab developed an algorithm to link similar cell types across evolutionary distances. Their method, detailed in a paper published May 4 in eLife, is designed to compare cell types in different species.

Study lead author Alexander Tarashansky is a 2015 SGF and 2018 SIGF Fellow, and co-author Margarita Khariton is a 2017 SIGF Fellow.
