Trypsinised cells and explants from human breast carcinomas (one of which proved to be normal tissue) were set up in culture. A variety of media and additives (hormones etc.) were used to stimulate vigorous cell growth. The trypsinised cells failed to grow but in seven of the twelve tumors, the explants grew successfully for a period of at least five weeks.
