Here, we outline a convenient, alternative approach to isolation and culture of viable myocytes and non-myocytes from the adult mouse heart, developed in our lab. The technique requires only common surgical and laboratory equipment, and involves direct needle perfusion of the left ventricle ex vivo. Viable myocyte yields and functionality are comparable to those described in established Langendorff-based protocols.

Since publication, this procedure has been reproduced and established in other labs, worldwide. We continue to collaborate and advise on implementation and troubleshooting, please get in touch!
