Improved cell sources

Definition

Improved cell sources refer to enhanced or optimized types of cells used in tissue engineering, specifically aimed at creating functional cartilage. These sources may include stem cells, chondrocytes from different origins, or genetically modified cells that can provide better proliferation and differentiation capabilities necessary for successful cartilage regeneration.

5 Must Know Facts For Your Next Test

1. Improved cell sources can significantly enhance the quality and functionality of engineered cartilage, addressing challenges like poor integration and mechanical properties.
