Discussion

A method shows enhanced Proteoglycan-4 expression in superficial zone chondrocytes, suggesting better bioengineered cartilage outcomes.

SZC cultured on CD-ECM exhibited improved attachment and proliferation rates, accelerating confluency.
Cells on CD-ECM showed a significant reduction in dedifferentiation markers and smaller cell size.
Tissues formed from SZC expanded on CD-ECM demonstrated higher levels of Proteoglycan-4, along with collagen II and aggrecan expression.
Using CD-ECM for SZC passaging could enhance their viability for bioengineering applications.

Manzoni et al. (2025) studied this question.
