iChip

The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...

  • To bridge developmental biology, clinical medicine, and tissue engineering for artificial islet development.

Main Methods:

  • Analysis of native islet structures and functions.
  • Review of stem cell-derived islet generation protocols.
  • Investigation of various artificial islet fabrication techniques, emphasizing hydrogel-based methods.

Main Results:

  • Detailed examination of natural islet biology and function.
  • Overview of stem cell protocols for islet generation.
  • Exploration of diverse artificial islet construction techniques, including hydrogels.
  • Summary of materials and devices for clinical applications.

Conclusions:
