Extracellular matrix hydrogel derived from decellularized tissues enables endoderm organoids culture

Project description:Organoids have huge therapeutic potential and are increasingly opening up new avenues within regenerative medicine. However, the clinical application is greatly limited by the lack of effective GMP-complaint systems for organoid expansion in culture. Here, we envisage that the use of extracellular matrix hydrogels derived from decellularized tissues (DT) can provide the instructive native environment necessary to direct cell growth. These gels possess the biochemical signature of tissue-specific ECM, and have the potential for clinical translation due to their natural, non-carcinogenic origin. We show that gels developed from decellularized porcine small intestinal mucosa have similar physiological range and mechanical properties to commercially available gels. ECM-derived gels enable formation and growth of endoderm-derived organoids and, moreover, supports in vivo organoid growth. The development of these ECM-derived hydrogels opens up the potential for human organoids to be used clinically.

Here, we envisage that the use of extracellular matrix hydrogels derived from decellularized tissues (DT) can provide an environment capable of directing cell growth. These gels possess the biochemical signature of tissue-specific ECM, and have the potential for clinical translation. Gels from decellularized porcine small intestinal mucosa/submucosa enable formation and growth of endoderm-derived human organoids, such as gastric, liver, pancreas, and small intestine. ECM gels could be used for direct organoids derivation from human biopsies, multiple passages with transcriptomic signature comparable to gold standard culture system, and in vivo organoid delivery. The development of these ECM-derived hydrogels opens up the potential for human organoids to be used clinically.

Bioactive decellularized extracellular matrix-based hydrogel supports human adipose tissue-derived stem cell maintenance and fibrocartilage phenotype

Project description:Decellularized extracellular matrix (dECM)-based hydrogels combined with hASCs could serve as an interface for studying behavior and differentiation properties in a cartilage microenvironment. In the present study, we described the behavior of hASCs cultured in a commercial dECM MatriXpec™. The protein composition of MatriXpec™ was accessed by mass spectrometry and is mainly represented by collagen proteins, building an hydrogel fibrous ultrastructure.

Tissue extracellular matrix hydrogels as alternative to Matrigel for culturing gastrointestinal organoids

Project description:To determine the performance of the decellularized GI tissue ECM hydrogel, we analyzed differences in mRNA expression levels in native gastric tissues, gastric organoids cultured in Matrigel and those cultured in decellularized gastric ECM hydrogel. We also compared mRNA expression levels of native small intestinal tissues, small intestinal organoids grown in Matrigel and those grown in decellularized intestinal ECM hydrogel.

Delineation of in vitro chondrogenesis of human synovial stem cells following preconditioning with decellularized matrix

Project description:As a tissue-specific stem cell for chondrogenesis, synovium-derived stem cells (SDSCs) are a promising cell source for cartilage repair. However, a small biopsy can only provide a limited number of cells. Cell senescence from both in vitro expansion and donor age presents a big challenge for stem cell based cartilage regeneration. Here we found that expansion on decellularized extracellular matrix (dECM) full of three-dimensional nanostructured fibers provided SDSCs with unique surface profiles, low elasticity but large volume as well as fibroblast-like shape. dECM expanded SDSCs yielded large pellets with intensive staining of type II collagen and sulfated GAGs, which was supported by both biochemical data and real-time PCR results. Our results also hint at lower levels of inflammatory genes and how they might be responsible for enhanced chondrogenic differentiation in dECM expanded SDSCs. Despite an increase of type X collagen in chondrogenically induced cells, dECM expanded cells had significantly lower potential for endochondral bone formation. Both Wnt and MAPK signals were actively involved in both expansion and chondrogenic induction of dECM expanded cells. dECM expanded human SDSCs could be a potential cell source for autologous cartilage repair Adult human synovial fibroblasts (4 donors, two male and two female, average 43 years old, all had no known joint disease) were grown for one passage on plastic flasks (P cells) or plastic flasks pre-coated with decellularized extracellular matrix (E cells). Aliquots were centrifuged and pellets cultured for 35 days in serum-free chondrogenic medium (P pellet or E pellet). There are no replicates.

Engineered hydrogel reveals contribution of matrix mechanics to esophageal adenocarcinoma and identifies matrix-activated therapeutic targets [RNA-seq]

Project description:Increased extracellular matrix (ECM) stiffness has been implicated in esophageal adenocarcinoma (EAC) progression, metastasis, and resistance to therapy. However, the underlying pro-tumorigenic pathways are yet to be defined. Additional work is needed to develop physiologically relevant in vitro 3D culture models that better recapitulate the human tumor microenvironment and can be used to dissect the contributions of matrix stiffness to EAC pathogenesis. Here, we describe a modular, tumor ECM-mimetic hydrogel platform with tunable mechanical properties, defined presentation of cell-adhesive ligands, and protease-dependent degradation that supports robust in vitro growth and expansion of patient-derived EAC 3D organoids (EAC PDOs). Hydrogel mechanical properties control EAC PDO formation, growth, proliferation, and activation of tumor-associated pathways that elicit stem-like properties in the cancer cells, as highlighted through in vitro and in vivo environments. We also demonstrate that the engineered hydrogel serves as a platform to identify potential therapeutic targets to disrupt the contribution of pro-tumorigenic matrix mechanics in EAC. Together, these studies show that an engineered PDO culture platform can be used to elucidate underlying matrix-mediated mechanisms of EAC, and inform the development of therapeutics that target ECM stiffness in EAC.

Delivery of a tissue derived extracellular matrix gel improves recovery following both acute and chronic disuse muscle injuries.

Project description:To evaluate decellularized skeletal muscle extracellular matrix hydrogel effectiveness in treating disuse atrophy using a mouse hindlimb suspension (HU) model. Male C57BL/6J mice were subjected to 5 days of hind limb unloading then received intramuscular matrix gel on the left TA. We then performed gene expression profiling analysis using data obtained from RNA-seq from mouse TA muscles (n=4 for matrix gel treatment, n=4 for PBS control , and n=4 for uninjured control) at day 7 post matrix gel injection

Porcine breast extracellular matrix hydrogel for spatial tissue culture

Project description:Porcine mammary fatty tissues represent an abundant source of biomaterial for generation of breast-specific extracellular matrix (ECM). Here we report the extraction of total ECM proteins from pig breast fatty tissues, the fabrication of hydrogel scaffolds from the extracted ECM proteins, the structural properties of the scaffolds, and the applications of the hydrogel in human mammary epithelial cell spatial cultures for cell surface receptor expression, metabolomics characterization, acini formation, proliferation, migration between different scaffolding compartments, and in vivo tumor formation. This model system provides an additional option for studying human breast diseases such as breast cancer.
