3D Culture of MIN-6 Cells on Decellularized Pancreatic Scaffold: In Vitro and In Vivo Study

الملخص EN

Type 1 diabetes is an autoimmune disease which is due to the lack of β cells.

The ideal therapy to cure the disease is pancreas transplantation, but its application is confined to a limited number of people due to the shortage of organ and the need for life-long immunosuppression.

Regenerative medicine methods such as a tissue engineered pancreas seem to provide a useful method.

In order to construct a microenvironment similar to the native pancreas that is suitable for not only cell growth but also cellular function exertion, a decellularized mouse pancreas was used as a natural 3D scaffold in this experiment.

MIN-6 β cells were planted in the bioscaffold.

The cell engraftment was verified by HE staining and SEM.

Immunostaining procedures were performed to confirm the normal function of the engrafted cells.

qRT-PCR demonstrated that insulin gene expression of the recellularized pancreas was upregulated compared with conventional plate-cultured cells.

In vivo experiment was also accomplished to further evaluate the function of the recellularized bioscaffold and the result was inspiring.

And beyond doubt this will bring new hope for type 1 diabetic patients.
