Project description:Collagenase digestion (d) and cellular outgrowth (og) are the current modalities of meniscus fibrochondrocytes (MFC) isolation for bioengineering and mechanobiology related studies. However, how these modalities may impact study outcomes are unknown. Here, we show og- and d-isolated MFC have distinct proliferative capacity, transcriptomic profiles via RNA sequencing (RNAseq), extracellular matrix (ECM)-forming and migratory capacities. Our data show that microtissue models developed from og-isolated MFC display a contractile phenotype with higher expressions of α-smooth muscle actin (ACTA2) and transgelin (TAGLN) and are mechanically stiffer than their counterparts from d-MFC. Moreover, we introduce a novel method of MFC designated digestion-after-outgrowth (dog). The transcriptomic prolife of dog-MFC are distinct from d-and og-MFC including a higher expression of mechanosensing caveolae-associated caveolin-1 (CAV1). Additionally, dog-MFC were superior chondrogenically and generated larger-size microtissue models containing a higher frequency of smaller collagen fiber diameters. Thus, we demonstrate that the modalities of MFC isolation influences the downstream outcomes of bioengineering and mechanobiology-related studies.

Project description:The aim of this study is to demonstrate that mechanical unloading via SMG will induce a higher osteoarthritic-like gene profile in bioengineered meniscal cartilage from healthy female MFC versus healthy male MFC. This would serve as the molecular basis for early onset of knee osteoarthritis in females
