With ongoing clinical trials using human pluripotent stem cells (hPSCs), there is a need for rapid and controlled expansion of the cells to meet demand. Current approaches towards scalable hPSC culture use undefined animal products or expensive human-based proteins. Additionally, these products don’t support single-cell culture – which is necessary for large scale biomanufacturing – and result in only about 30 percent cell survival. Unlike these traditional substrates, VitaCapsule is low cost, free of animal products, and supports single cell viability in both planar (2D) and suspension (3D) culture.

Technology Description

VitaCapsule is a low cost synthetic peptide-conjugated hydrogel system for hPSC manufacturing. The goal of our technology is to enhance the viability of hPSCs, which in turn promotes clonal expansion – generating many copies of a single cell – and enables mass production. Isolated hPSCs do not survive well on their own because they lack cell-cell contact signals, which triggers cell death. VitaCapsule mimics these intercellular interactions using short peptides that bind with hPSCs and then encapsulate them, forming a protective barrier. This support system doubles hPSC survival rate compared to current culture methods.
