Still my favorite 3D reconstruction of a pancreatic tissue.
Using the CODA workflow, we mapped a billion individual cells in 3D.
Red: pre-cancer lesions
Navy blue: ducts
Light blue: islets of Langerhans
Purple: acini
Green: blood vessels
Yellow: fat

We have written two reviews providing a practical guide and fundamentals of cell migration:
(1) How to select an optimal cell migration assay,
(2) How to analyze cell migration data.
We also added a perspective on AI methods of analysis.
Coming out soon in Nature Methods.

Our recent observations are distinct from conventional active matter. Self-propelled colloidal particles neither secrete inhibitory molecules, nor actively modulate adhesion molecules, which are two key ingredients leading to our observed patterned aggregates.

It’s that time of the year again when we celebrate the amazing achievements and discoveries made by Johns Hopkins faculty.
We take over the Peabody Library so that awardees of our internal grants get a chance to talk to one another and forge new collaborations

High-throughput screening of drugs that affect cell proliferation is easily done using a plate reader.
No such luck for cell migration. So, we developed an assay for label-free deep learning-based automated cell tracking.

We use CODA to map human endometrial tissue at single-cell resolution, a map that then serves as a blueprint to design a multi-compartment multicellular assembloid of the endometrium.

CAR T therapy has seen great effectiveness in liquid tumors, but little in solid tumors (e.g. ovarian cancer).
Here we developed hyper-migratory CAR TV cells to infiltrate en masse ovarian tumors. (Left: control CAR T cells; right CAR TV cells).
