Allen Cell Structure Segmenter: A Machine learning toolkit that lets biologists navigate their way through a 3D cell
We present the Allen Cell Structure Segmenter, a python-based, open-source toolkit that combines classic 3D image segmentation with artificial intelligence to detect cellular structures.
Read more about this new toolkit and how it can help biologists analyze their 3D images of cells and be more quantitative with their results.
The Allen Institute today released the Integrated Mitotic Stem Cell, a data-driven model and visualization tool that captures — for the first time — a holistic view of human cell division. By enabling a deeper understanding of how healthy human cells divide, a process known as mitosis, the model will further basic biology research as well as studies of cancer, a disease that often results from cell division gone awry.

Event highlights include:
A new online discussion forum offers a meeting spot for the gene-editing and stem cell research community to interact with one another and with the scientists that created the Allen Institute's fluorescently tagged human induced pluripotent stem cell (hiPSC) line collection.
Researchers at the Allen Institute for Cell Science were interviewed around the question "what don't we know about cells?" A full article summarizing their responses is available at alleninstitute.org.
Scientists at the Allen Institute have used machine learning to train computers to see parts of the cell the human eye cannot easily distinguish. Using 3D images of fluorescently labeled cells, the research team taught computers to find structures inside living cells without fluorescent labels, using only black and white images generated by an inexpensive technique known as brightfield microscopy. A study describing the new technique is published today in the journal Nature Methods.
Our new Jove Video Journal article presents a protocol we developed for tagging endogenously expressed proteins with fluorescent tags in human induced pluripotent stem cells using CRISPR/Cas9. Putatively edited cells are enriched by fluorescence activated cell sorting and clonal cell lines are generated.
The Allen Cell Collection now contains five new fluorescently tagged stem cell lines, including the first cells in the collection with a tag specific to heart muscle cells, or cardiomyocytes. To date, all the cell lines have been gene edited to carry a fluorescent marker that is produced in undifferentiated cells, before they go on to become specific cell types, like cardiomyocytes, nerve cells or liver cells.
Our 3rd Allen Cell Methods video released: Setting up the WTC parental line for cardiac differentiation
We have released a new Instructional Video.
To ensure researchers have success working with our human induced pluripotent stem cell lines in their lab, our Angel Nelson highlights nuanced techniques and helpful tips while demonstrating our cardiac differentiation protocol for the WTC parental line and our gene-edited cells. If the experiment is successful, you can expect to see beating cardiomyocytes at day 7.
