About pepgel
Unlike conventional 2D cultures or legacy artificial “3D” aggregates, our patented PGmatrix™ platform provides a true physiological microenvironment that mirrors the body’s own regenerative processes ensuring the preservation of structural and functional cellular integrity. Our innovative PGmatrix technology faithfully mimics the human extracellular matrix, unlocking new possibilities in regenerative medicine through transformative stem cell innovations and tissue regeneration. Our advanced solutions also propel progress in drug discovery, disease modeling, and in vivo drug delivery, accelerating the path from research to therapy.
The PepGel portfolio encompasses four core product lines: PGmatrix 3D Cells, PGmatrix Stem-X, PGmatrix Bioink, and PGmatrix Injection. Complementing these product lines, we also provide custom hydrogel formulations, hiPSC-derived somatic cells, and advanced 3D tumor and organoid models for precise drug efficacy and toxicity testing and regenerative medicine.
We move health forward, inspired by you.
PepGel is dedicated to advancing regenerative medicine and life sciences through the creation of physiologically relevant, next-generation hydrogel platforms that faithfully mimic the human extracellular matrix. Our pioneering technologies empower transformative innovations in 3D cell culture, organoid development, tissue regeneration, stem cell therapies, biomedical engineering, injectable therapeutics, and wound healing, bridging discovery to clinical impact. Guided by strong commitments to ethics, scientific excellence, and social responsibility, PepGel strives to improve human health while creating lasting value for our partners and the communities we serve.
