Metatissue® hPCMA - Human Methacryloyl Placenta Photopolymerizable Hydrogel

A human-derived and collagen-rich hydrogel platform! Introduction Metatissue® hPCMA Photopolymerizable Hydrogel is a human based, xeno-free, bioactive placenta-based platform that provides physiologically relevant microenvironments for cells culture. The precursor solution is easily prepared by reconstituting hPCMA lyophilizate in an aqueous solution with a photoinitiator. Afterwards, it can be cured upon light exposure to form a hydrogel with tuneable mechanical properties. hPCMA Photopolymerizable Hydrogels provide great control over gelation time and matrix stiffness, enabling researchers to create the cell culture environment that better fits their needs. Advantages Human-derived: Multiple native human-derived extracellular matrix proteins provide a xeno-free alternative to animal products. Mechanically tuneable: Mechanical properties can be easily adjusted to obtain several tissue stiffness simulations. Photocrosslinkable: The precursor solution can be cured upon light exposure to induce hydrogel crosslinking. Its temperature stability allows for easier handling. Versatile: Easily processed in multiple geometries and in microarrays amenable to organ-on-a-chip systems designed for high throughput screening applications. Reproducible: The materials are prepared from multiple donor units that are pooled to minimize lot-to-lot variation. hPCMA Material Metatissue® hPCMA Photopolymerizable Hydrogel is composed of several extracellular matrix (ECM) proteins, including multiple collagen types (e.g., I, III, IV, and VI), as well as fibrinogen, laminin, fibrillin, and fibronectin. These bioactive components are well recognized as key constituents of the extracellular matrix, playing crucial roles in supporting cell adhesion, growth, and proliferation. Main Components: Collagen Type I, III, IV, and VI Laminin Fibronectin Fibrinogen Fibrillin Source: hPCMA is manufactured from human placentas (hPCs) obtained from licensed healthcare establishments after the donor’s informed consent. All placenta donations are compliant with the Convention on Human Rights and Biomedicine, and Data Protection Regulation. It is essential to observe universal precautions for handling and disposing of biological products while working with hPCMA. Photoinitiated Polymerization: hPCMA is chemically modified with photoresponsive groups to polymerize only when exposed to ultraviolet (UV) or visible light. Therefore, a photoinitiator is required to initiate the polymerization process (not provided). For recommended photoinitiators, please refer to the Instructions for Use (IFU). Specifications Product Category: Hydrogels, scaffolds, biomatrices Product Type: Hydrogel Liquid/Powder: Lyophilized powder Size: 10 mg or 100 mg vials Storage: 2-8°C Manufacturer: Metatissue® Country of Origin: Portugal hPCMA Validation in Cell Culture Validated Cell Types These are some of the human cells already validated with the hPCMA product: Bone Marrow Mesenchymal Stem Cells (BM-MSC) Human Umbilical Vein Endothelial Cells (HUVEC) Cardiac Human Induced Pluripotent Stem Cells-derived Cardiomyocytes (iPSC-CM) Human Cardiac Fibroblasts (hCF) Neuronal Primary murine forebrain neurons Vascular Human Induced Pluripotent Stem Cells-derived Vascular population (EC, PC, SMC) Tunable Stiffness hPCMA Photopolymerizable Hydrogel has tunable mechanical properties adjusted by the concentration of hPCMA lyophilizate in the precursor solution. It is therefore possible to obtain hydrogels with different stiffness to closely mimic the mechanical properties of various native tissues. Cell Viability & Proliferation Several types of encapsulated cells, namely, human adipose-derived stem cells (hASCs), HepG2 cells (human liver cancer cell line) and SW982 cells (synovial sarcoma cell line) maintain their viability for at least 7 days and are able to proliferate inside the hydrogels.

It can also be added to new ink formulations as a complement for a human touch.
