Therapeutic biomolecules produced from cells encapsulated within alginate microcapsules (MCs) offer a potential treatment for a number of diseases. However the fate of such MCs once implanted into the body is difficult to establish. Labelling the MCs with medical imaging contrast agents may aid their detection and give researchers the ability to track them over time thus aiding the development ...

Differentiation and maturation of porcine neonatal pancreatic cell clusters (NPCCs) microencapsulated in barium alginate were assessed after transplantation into immunocompetent mice. Microencapsulated NPCCs were transplanted into the peritoneal cavity of streptozocin-induced diabetic B6AF1 mice (n = 32). The microcapsules were removed at 2, 6, and 20 weeks and examined for cellular overgrowth,...

A potentially cost-effective strategy for gene therapy of hemophilia B is to create universal factor IX-secreting cell lines suitable for implantation into different patients. To avoid graft rejection, the implanted cells are enclosed in alginate-polylysine-alginate microcapsules that are permeable to factor IX diffusion, but impermeable to the hosts' immune mediators. This nonautologous approa...

Damping-off disease due to Pythium aphanidermatum is one of the most harmful diseases cucumber. One critical issues in field biological control establishment a link between beneficial bacteria screened laboratory and its industrial application. Therefore, when developing biocontrol agents, it necessary study optimization mass production conditions select suitable carrier for their final formula...

This study aimed to develop and evaluate barium and calcium microcapsules as candidates for scaffolding in artificial dermal papilla. Dermal papilla cells (DPCs) were isolated and cultured by one-step collagenase treatment. The DPC-Ba and DPC-Ca microcapsules were prepared by using a specially designed, high-voltage, electric-field droplet generator. Selected microcapsules were assessed for lon...
