Lab-grown blood given to people in world-first clinical trial
Obviously if this succeeds, then the life-saving implications are tremendous. It would become practical to keep a stock of lab-grown blood in ambulances, as it can just be rotated out when it expires, but the immediate availability of blood in the field can mean the difference between life and death.I just hope that blood donation doesn't go away as a result. There are both ethical and personal benefits - ethical, because it's a visceral experience of doing something good for society that most people can do, and with little effort; personal, because of potential health benefits from donating blood, see e.g. https://jamanetwork.com/journals/jamanetworkopen/fullarticle... .
