Artificial organs versus regenerative medicine: is it true?

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Medical Technology

Background:

• The fields of artificial organs and regenerative medicine are often perceived as separate, with some believing artificial organs are outdated.
• However, artificial organs have historically functioned as essential bridges to facilitate tissue regeneration.

Purpose of the Study:

• To challenge the notion that artificial organs are obsolete and to redefine their role in conjunction with regenerative medicine.
• To highlight the synergistic relationship between artificial organ technologies and regenerative medicine for advancing patient care.

Main Methods:

• Reviewing the historical and current applications of artificial organs.
• Categorizing artificial organs based on their function in promoting or supporting regeneration (in situ, sustaining function, accelerating regeneration).

Main Results:

• Artificial organs act as bridges to regeneration by promoting in situ tissue repair, sustaining organ function during regeneration, or accelerating the regenerative process.
• Examples include vascular prostheses, artificial kidneys, and blood oxygenators, all contributing to natural tissue regeneration.
• The success of artificial organs lies in their ability to support regeneration within the patient's body.

Conclusions:

• Artificial organs and regenerative medicine are complementary, not competing, technologies.
• Joint development programs integrating artificial organ and regenerative medicine technologies are essential for future medical advancements.
• Utilizing both man-made and natural tissue-derived substitutes will improve future medical care.
