CellDrop FAQ

What is our Product?

A vial filled with living stem cells encapsulated inside microscopic hydrogel droplets.

How does it work?

Droplets are injected into an injury with a standard syringe. They stick to tissue, enabling the encapsulated stem cells within to remain precisely where they belong.

What makes it better
  • Cells are kept alive and localized at an injury longer,
    resulting in faster and more resilient tissue repair. Porous hydrogel droplets protect cells while allowing for free exchange of nutrients, cell signals, and waste.
  • Hydrogel encapsulation prevents immune rejection, enabling the use of allogeneic cells and the creation of scalable, off the shelf therapies.

Celldrop's Process

CellDrop’s encapsulation platform enables the use of allogeneic cells without immune rejection. Our stem cells are selected from a single, carefully screened donor for consistent potency. They are then culture expanded, encapsulated, and frozen for storage— ready to be shipped to customers as needed. In this way, our therapy is both scalable and off the shelf ready.


Damaged rat Achilles tendons treated with CellDrop encapsulated stem cells have more healthy tendon tissue regenerated , less unwanted hyper cellularization, and better aligned collagen fibers than tendons treated with conventional “naked” stem cells or the Phosphate Buffered Saline  injection control. These results suggest less inflammation, less scar tissue formation, and more durable healing with CellDrop encapsulated stem cells.
