The development and application of decellularized extracellular matrices (ECM) has grown rapidly in the fields of cell biology, tissue engineering and regenerative medicine in recent years. Similar to decellularized tissues and whole organs, cell-derived matrices (CDMs) represent bioactive, biocompatible materials consisting of a complex assembly of fibrillar proteins, matrix macromolecules and associated growth factors that often recapitulate, at least to some extent, the composition and organization of native ECM microenvironments. The unique ability to engineer CDMs de novo based on cell source and culture methods makes them an attractive alternative to conventional allogeneic and xenogeneic tissue-derived matrices that are currently harvested from cadaveric sources, suffer from inherent heterogeneity, and have limited ability for customization. Although CDMs have been investigated for a number of biomedical applications, including adhesive cell culture substrates, synthetic scaffold coatings, and tissue engineered products, such as heart valves and vascular grafts, the state of the field is still at a relatively nascent stage of development. In this review, we provide an overview of the various applications of CDM and discuss successes to date, current limitations and future directions.

Unlabelled: Di(2-ethhylhexyl) phthalate (DEHP) is a common plastic rubberizer. DEHP leaches from plastic matrices and is under increasing scrutiny as numerous studies have linked it to negative human health manifestations. Coxsackievirus B3 (CVB) is a human pathogen that typically causes subclinical infections but can sometimes cause severe diseases such as pancreatitis, myocarditis, and meningoencephalitis.

Ovarian organoids are essential in female reproductive medicine, enhancing our understanding of ovarian diseases and improving treatments, which benefits women's health. Constructing ovarian organoids involves two main processes: differentiating induced pluripotent stem cells (iPSCs) into germ and ovarian somatic cells to restore ovarian function and using extracellular matrix (ECM) to create a suitable ovarian microenvironment and scaffold. Although the technology is still in its early stages, future advancements will likely involve integrating high-throughput analysis, 3D-printed scaffolds, and efficient iPSC induction, driving progress in reproductive and regenerative medicine.

Stem cell-derived blood vessel organoids are embedded in extracellular matrices to stimulate vessel sprouting. Although vascular organoids in 3D collagen I-Matrigel gels are currently available, they are primarily capillaries composed of endothelial cells (ECs), pericytes, and mesenchymal stem-like cells, which necessitate mature arteriole differentiation for neovascularization. In this context, the hypothesis that matrix viscoelasticity regulates vascular development is investigated in 3D cultures by encapsulating blood vessel organoids within viscoelastic gelatin/β-CD assembly dynamic hydrogels or methacryloyl gelatin non-dynamic hydrogels.

The interaction between cancer cells and the extracellular matrix (ECM) plays a pivotal role in tumour progression. While the extracellular degradation of ECM proteins has been well characterised, ECM endocytosis and its impact on cancer cell progression, migration, and metastasis is poorly understood. ECM internalisation is increased in invasive breast cancer cells, suggesting it may support invasiveness.

Rationale: Pancreatic stellate cells (PSCs) produce a collagen-rich connective tissue in chronic pancreatitis and pancreatic ductal adenocarcinoma (PDAC). Ca-permeable ion channels such as ORAI1 are known to affect PSC proliferation and myofibroblastic phenotype. However, it is unknown whether these channels play a role in collagen secretion.
