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:Craniofacial microsomia (CFM) is a congenital defect that usually results from aberrant development of embryonic pharyngeal arches. However, the molecular basis of CFM pathogenesis is largely unknown. Here we employ zebrafish model to investigate the mechanism of CFM pathogenesis. In early embryos, tet2 and tet3 are highly expressed and are essential for pharyngeal cartilage development. Single-cell RNA sequencing and genetic analyses reveal that loss of Tet2/3 impaired chondrocyte differentiation largely due to insufficient BMP signaling. Mechanistically, Tet2/3-mediated 5-hydroxymethylcytosine modification allows the 5-hydroxymethylcytosine “reader”, Sall4, to specifically bind the bmp4 promoter, thereby promoting bmp4 expression and enabling efficient BMP signaling. These findings indicate the TET-BMP regulatory axis via 5-hydroxymethylcytosine to be critical for pharyngeal cartilage development. Whole-exome sequencing of CFM patient samples show that single nucleotide polymorphisms in TET and BMP pathway genes increase the risk of CFM. Collectively, our study provides novel insights into understanding craniofacial development and CFM pathogenesis.

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

Project description:Craniofacial microsomia (CFM) is a congenital defect that usually results from aberrant development of embryonic pharyngeal arches. However, the molecular basis of CFM pathogenesis is largely unknown. Here, we employ the zebrafish model to investigate mechanisms of CFM pathogenesis. In early embryos, tet2 and tet3 are essential for pharyngeal cartilage development. Single-cell RNA sequencing reveals that loss of Tet2/3 impairs chondrocyte differentiation due to insufficient BMP signaling. Moreover, biochemical and genetic evidence reveals that the sequence-specific 5mC/5hmC-binding protein, Sall4, binds the promoter of bmp4 to activate bmp4 expression and control pharyngeal cartilage development. Mechanistically, Sall4 directs co-phase separation of Tet2/3 with Sall4 to form condensates that mediate 5mC oxidation on the bmp4 promoter, thereby promoting bmp4 expression and enabling sufficient BMP signaling. These findings suggest the TET-BMP-Sall4 regulatory axis is critical for pharyngeal cartilage development. Collectively, our study provides insights into understanding craniofacial development and CFM pathogenesis.
