Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Review Description
The so-called “matricellular” proteins have recently emerged as important regulators of cell–extracellular matrix (ECM) interactions. These proteins modulate a variety of cell functions through a range of interactions with cell-surface receptors, hormones, proteases and structural components of the ECM. As such, matricellular proteins are crucial regulators of cell phenotype, and consequently tissue function. The distinct cell types and microenvironments that together form the IVD provide an excellent paradigm to study how matricellular proteins mediate communication within and between adjacent tissue types. In recent years, the role of several matricellular proteins in the intervertebral disc has been explored in vivo using mutant mouse models in which the expression of target matricellular proteins was deleted from either one or all compartments of the intervertebral disc. The current review outlines what is presently known about the roles of the matricellular proteins belonging to the CCN family, SPARC ( S ecreted P rotein, A cidic, and R ich in C ysteine), and thrombospondin (TSP) 2 in regulating intervertebral disc cell–ECM interactions, ECM synthesis and disc tissue homeostasis using genetically modified mouse models. Furthermore, we provide a brief overview of recent preliminary studies of other matricellular proteins including, periostin (POSTN) and tenascin (TN). Each specific tissue type of the IVD contains a different matricellular protein signature, which varies based on the specific stage of development, maturity or disease. A growing body of direct genetic evidence links IVD development, maintenance and repair to the coordinate interaction of matricellular proteins within their respective niches and suggests that several of these signaling modulators hold promise in the development of diagnostics and/or therapeutics targeting intervertebral disc aging and/or degeneration.
