Imaging Calcium Dynamics in Subpopulations of Mouse Pancreatic Islet Cells08:03

Imaging Calcium Dynamics in Subpopulations of Mouse Pancreatic Islet Cells

Here, we present a protocol for imaging and quantifying calcium dynamics in heterogeneous cell populations, such as pancreatic islet cells. Fluorescent reporters are delivered into the peripheral layer of cells within the islet, which is then immobilized and imaged, and per-cell analysis of the dynamics of fluorescence intensity is...

Harvest and Primary Culture of Leptomeningeal Lymphatic Endothelial Cells06:44

Harvest and Primary Culture of Leptomeningeal Lymphatic Endothelial Cells

Leptomeningeal lymphatic endothelial cells (LLECs), a recently identified intracranial cell type, have poorly understood functions. This study presents a reproducible protocol for harvesting LLECs from mice and establishing in vitro primary cultures. This protocol is designed to enable researchers to delve into the cellular functions and potential clinical implications of...
