Abstract
Orally administered "tortoiseshell and deer antler gelatin" is a common traditional medicine for patients with osteoporosis or osteoarthritis. From the pepsin-digested gelatin, we previously isolated and identified the osteoblast-stimulating pentapeptide, TSKYR. Its trypsin digestion products include the dipeptide YR, enhancing calcium ion uptake, and tripeptide TSK, resulting in remarkable 30- and 50-fold increases in mineralized nodule area and density in human osteoblast cells. These peptides were chemically synthesized in this study. The composition of deer antler preparations comprises not only proteins and peptides but also a significant quantity of metal ion salts. By analyzing osteoblast growth in the presence of peptide YR and various metal ions, we observed a synergistic effect of calcium and strontium on the effects of YR. Those peptides could also stimulate the growth of C2C12 skeletal muscle cells and human chondrocytes, increasing collagen and glycosaminoglycan content in a three-dimensional environment. The maintenance of bone homeostasis relies on a balance between osteoclasts and osteoblasts. Deer antler peptides were observed to inhibit osteoclast differentiation, as evidenced by ROS generation, tartrate-resistant acid phosphatase (TRACP) activity assays, and gene expression in RAW264.7 cells. In summary, our findings provide a deep understanding of the efficacy of this folk medicine.

Abstract
Chondrocytes are well adapted to hypoxia and produce more functional extracellular matrix in low oxygen environments in vitro. In our previous study, methyltransferase SET domain containing (SETD)7 regulated chondrocyte activity in hypoxic conditions. However, the precise association between SETD7 and chondrocyte differentiation under low oxygen partial pressure remains unclear. The association between SETD7 and chondrocyte differentiation was studied by silencing SETD7 in chondrocytes in vitro. The results showed that the silencing of SETD7 in ATDC5 cells inhibited the Hippo signaling pathway, decreased Yes-associated protein (YAP) phosphorylation and increased the levels of YAP and hypoxia inducible factor-1α (HIF-1α) in the nucleus. YAP combined with HIF-1α to form a complex that promoted the expression of genes involved in chondrogenic differentiation and the glycolytic pathway. Thus, SETD7 inhibited chondrocyte differentiation and glycolysis via the Hippo signaling pathway. The present study demonstrated that SETD7 was a potential molecular target that maintained the chondrocyte phenotype during cartilage tissue engineering and cartilage-associated disease.

Abstract
Among many factors of controlling stem cell differentiation, the key transcription factor upregulation via physical force is a good strategy on the lineage-specific differentiation of stem cells. The study aimed to compare growth and myogenic potentials between the parental cells (PCs) and the 1-day-old C2C12 spheroid-derived cells (SDCs) in two-dimensional (2D) and three-dimensional (3D) culture conditions through examination of the cell proliferation and the expression of myogenic genes. The data showed that 1-day-old spheroids had more intense expression of MyoD gene with respect to the PCs. The proliferation of the SDCs is significantly higher than the PCs in a time-dependent manner. The SDCs had also significantly higher myogenic potential than the PCs in 2D and 3D culture conditions. The results suggest that MyoD gene upregulation through cell-cell contacts is the good approach for preparation of seed cells in muscle tissue engineering.

Evaluation of a Cell-Free Collagen Type I-Based Scaffold for Articular Cartilage Regeneration in an Orthotopic Rat Model. MATERIALS 2020; 13:ma13102369. [PMID: 32455683 PMCID: PMC7287598 DOI: 10.3390/ma13102369] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 05/16/2020] [Accepted: 05/19/2020] [Indexed: 12/23/2022]
Abstract
The management of chondral defects represents a big challenge because of the limited self-healing capacity of cartilage. Many approaches in this field obtained partial satisfactory results. Cartilage tissue engineering, combining innovative scaffolds and stem cells from different sources, emerges as a promising strategy for cartilage regeneration. The aim of this study was to evaluate the capability of a cell-free collagen I-based scaffold to promote cartilaginous repair after orthotopic implantation in vivo. Articular cartilage lesions (ACL) were created at the femoropatellar groove in rat knees and cell free collagen I-based scaffolds (S) were then implanted into right knee defect for the ACL-S group. No scaffold was implanted for the ACL group. At 4-, 8- and 16-weeks post-transplantation, degrees of cartilage repair were evaluated by morphological, histochemical and gene expression analyses. Histological analysis shows the formation of fibrous tissue, at 4-weeks replaced by a tissue resembling the calcified one at 16-weeks in the ACL group. In the ACL-S group, progressive replacement of the scaffold with the newly formed cartilage-like tissue is shown, as confirmed by Alcian Blue staining. Immunohistochemical and quantitative real-time PCR (qRT-PCR) analyses display the expression of typical cartilage markers, such as collagen type I and II (ColI and ColII), Aggrecan and Sox9. The results of this study display that the collagen I-based scaffold is highly biocompatible and able to recruit host cells from the surrounding joint tissues to promote cartilaginous repair of articular defects, suggesting its use as a potential approach for cartilage tissue regeneration.
