TheraCyte™ | Cell Encapsulation
The TheraCyte™ System
A membrane-based cell delivery platform developed for investigating the protection, function, and retrieval of implanted cells.
System Overview
Engineered to support cell-based research
The TheraCyte™ system uses biocompatible membranes intended to help protect encapsulated donor cells from the recipient’s immune cells while permitting exchange of nutrients and therapeutic molecules. The platform has been studied across multiple animal models and in limited historical human investigations.
Cell protection
The membrane barrier is designed to reduce direct immune-cell access to enclosed tissue, supporting investigation of allogeneic cell transplantation.
Implant research
Company-reported studies have evaluated tissue compatibility, graft function, and protein delivery in several animal models and limited human studies.
Accessible device design
The device is designed for subcutaneous placement and retrieval, enabling investigation of implanted cells and their performance.
Research Record
Investigated across a range of applications
The original TheraCyte System page reports research in rodents, rabbits, dogs, primates, and humans. Historical studies have explored:
- Diabetes research in rodent models
- Delivery of human growth hormone and erythropoietin
- Cell-based delivery of cytokines and monoclonal antibodies
- Parathyroid tissue and therapeutic-protein secretion in limited human studies
These are descriptions of reported research, not claims of approved clinical use or proven treatment outcomes in patients.
Historical Findings
Biocompatibility and retrievability
TheraCyte’s published company description reports human studies lasting up to one year that examined biocompatibility, immunoprotection, and secretion of parathyroid hormone from devices containing donor tissue. The company also reports that devices in those studies were well tolerated and retrievable.
