The e-incubator: a magnetic resonance imaging-compatible mini incubator

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Medical Imaging

Background:

• Tissue engineering requires noninvasive methods to assess construct development.
• Current imaging techniques necessitate sample removal, risking contamination and hindering further culture.
• This leads to wasted samples and suboptimal growth conditions.

Purpose of the Study:

• To develop a standalone, miniature incubator compatible with magnetic resonance imaging (MRI).
• To enable concurrent tissue culture and real-time evaluation of engineered tissues.
• To facilitate the study of tissue morphogenesis and improve pre-transplantation assessment.

Main Methods:

• Development of a microcontroller-controlled, MRI-compatible incubator (e-incubator).
• Automatic sensing and regulation of physiological conditions for tissue culture.
• Validation through 4-week culture of tissue-engineered bone constructs.

Main Results:

• The e-incubator successfully maintained physiological conditions for concurrent culture and MRI evaluation.
• Visualization of temporal and spatial morphogenesis in engineered bone constructs was achieved.
• The system demonstrated potential for filtering deficient constructs before implantation.

Conclusions:

• The e-incubator is a key advancement for real-time testing of engineered tissues.
• This technology supports the study of tissue development and enhances the success rate of tissue engineering.
• It addresses the need for integrated culture and evaluation systems in regenerative medicine.
