The PepGelTM PGmatrix-Spheroid (PG-S) is a powerful research biotool for 3D cell culture that produces high content physiological spheroids (3D colonies or organoids) with in vivo like bioinformatics at the exosome-level according to RNA sequencing analysis. The PGmatrix-Spheroid kit is specially designed for short or long term growth of spheroids in a large range of tunable gel strengths for various cell types including cancer cells, stem cells, and normal organ cells.  PGmatrix-Spheroid is a self-healing hydrogel that supports the bioprinting of cells, spheroids, and organoids into patterns by pipetting or extrusion printers without post-printing crosslinking aids.  The kit consists of a vial of the 2-4% PG-S  patented peptide nanofiber solution and a vial of the PGworks trigger solution and a vial of PGgrow (optional for hiPSCs). The PGmatrix nanofibrils are formulated into a basic or a customer desired cell culture medium in neutral pH. A 3D microenvironment can be formed accordingly for spheroid growth. With PG-S, cells no longer suffer acidic or chilled conditions; cultured cells are easily harvested from the matrix at a gel content of less than 1%, and all operating procedures can be completed at room or body temperature in neutral pH.
