Adipose Tissue Development Relies on Coordinated Extracellular Matrix Remodeling, Angiogenesis, and Adipogenesis. Biomedicines 2022; 10:biomedicines10092227. [PMID: 36140327 PMCID: PMC9496222 DOI: 10.3390/biomedicines10092227] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 08/31/2022] [Accepted: 09/02/2022] [Indexed: 11/24/2022] Open
Abstract
Despite developing prenatally, the adipose tissue is unique in its ability to undergo drastic growth even after reaching its mature size. This development and subsequent maintenance rely on the proper coordination between the vascular niche and the adipose compartment. In this review, the process of adipose tissue development is broken down to explain (1) the ultrastructural matrix remodeling that is undertaken during simultaneous adipogenesis and angiogenesis, (2) the paracrine crosstalk involved during adipose development, (3) the mechanical regulators involved in adipose growth, and (4) the proteolytic and paracrine oversight for matrix remodeling during adipose development. It is crucial to gain a better understanding of the complex relationships that exist between adipose tissue and the vasculature during tissue development to provide insights into the pathological tissue expansion of obesity and to develop improved soft-tissue reconstruction techniques.

Bi-phasic effect of gelatin in myogenesis and skeletal muscle regeneration. Dis Model Mech 2021; 14:273524.

Abstract
Skeletal muscle regeneration requires extracellular matrix (ECM) remodeling, including an acute and transient breakdown of collagen that produces gelatin. Although the physiological function of this process is unclear, it has inspired the application of gelatin to injured skeletal muscle for a potential pro-regenerative effect. Here, we investigated a bi-phasic effect of gelatin in skeletal muscle regeneration, mediated by the hormetic effects of reactive oxygen species (ROS). Low-dose gelatin stimulated ROS production from NADPH oxidase 2 (NOX2) and simultaneously upregulated the antioxidant system for cellular defense, reminiscent of the adaptive compensatory process during mild stress. This response triggered the release of the myokine IL-6, which stimulates myogenesis and facilitates muscle regeneration. By contrast, high-dose gelatin stimulated ROS overproduction from NOX2 and the mitochondrial chain complex, and ROS accumulation by suppressing the antioxidant system, triggering the release of TNFα, which inhibits myogenesis and regeneration. Our results have revealed a bi-phasic role of gelatin in regulating skeletal muscle repair mediated by intracellular ROS, the antioxidant system and cytokine (IL-6 and TNFα) signaling. Summary: Application of high- and low-dose gelatin to skeletal muscle revealed a bi-phasic role of gelatin in regulating skeletal muscle repair, which has translational implications for regenerative medicine.

J Cell Physiol 2019; 235:1821-1837. [PMID: 31432516 DOI: 10.1002/jcp.29100] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2019] [Accepted: 06/27/2019] [Indexed: 12/18/2022]
Abstract
Extracellular matrix (ECM) has a marked influence on adipose tissue development. Adipose tissue formation is initiated with proliferation of preadipocytes and migration before undergoing further differentiation into mature adipocytes. Previous studies showed that collagen I (col I) provides a good substratum for 3T3-L1 preadipocytes to grow and migrate. However, it remains unclear whether and how col I regulates adipogenic differentiation of preadipocytes. This study reports that lipid accumulation, representing in vitro adipogenesis of the 3T3-L1 preadipocytes or the mouse primary adipocyte precursor cells derived from subcutaneous adipose tissue in the inguinal region is inhibited by the culture on col I, owing to downregulation of adipogenic factors. Previous study shows that col I enhances 3T3-L1 cell migration via stimulating the nuclear translocation of yes-associated protein (YAP). In this study, we report that downregulation of YAP is associated with in vitro adipogenesis of preadipocytes as well as with in vivo adipose tissue of high-fat diet fed mice. Increased expression of YAP in the cells cultured on col I-coated dishes is correlated with repression of adipogenic differentiation processes. The inactivation of YAP using YAP inhibitor, verteporfin, or YAP small-interfering RNA enhanced adipogenic differentiation and reversed the inhibitory effect of col I. Activation of YAP either by the transfection of YAP plasmid or the silence of large tumor suppressor 1 (LATS1), an inhibitory kinase of YAP, inhibited adipogenic differentiation. The results indicate that col I inhibits adipogenic differentiation via YAP activation in vitro.
