A Bibliometric Review of Artificial Extracellular Matrices Based on Tissue Engineering Technology Literature: 1990 through 2019.

Artificial extracellular matrices (aECMs) are an extension of biomaterials that were developed as model environments for tissue cells that mimic the native in vivo target tissues' structure. This bibliometric analysis evaluated the research productivity regarding aECM based on tissue engineering technology. The Web of Science citation index was examined for articles published from 1990 through 2019 using three distinct aECM‑related topic sets. Data were also visualized using network analyses (VOSviewer). Terms related to scaffolds, collagen, hydrogels, and differentiation were reoccurring in the aECM‑related literature over time. Publications with terms related to a clinical direction (wound healing, stem cells, artificial skin, and bone regeneration) have steadily increased, as have the number of countries and institutions involved in the artificial extracellular matrix. As progress with 3D scaffolds continues to advance, it will become the most promising technology to provide a therapeutic option to repair or replace damaged tissue.
