Systems and methods that enable harvesting of cartilage from a subject (e.g., a patient) via a harvesting unit that mitigates or eliminates a requirement of dicing and/or separation/division of the cartilage by hand. The harvesting unit employs a power supply to accumulate and cut the cartilage. By employing the harvesting unit, an automatic accumulation and reduction of size for the cartilage is provided, while freeing a person from having to manually dice the cartilage.
