Artificial Womb Technology for Extremely Premature Neonates: Preclinical Neurodevelopmental Outcomes

Area of Science:

• Neonatal neurology
• Developmental neuroscience
• Bioengineering

Background:

• Extreme prematurity (22-24 weeks gestation) is associated with severe neurological and neurodevelopmental challenges.
• Current neonatal intensive care unit (NICU) survival rates for these infants remain limited, with significant long-term morbidities.
• There is a critical need for novel therapeutic strategies to improve outcomes for extremely preterm infants.

Purpose of the Study:

• To review current neurological and neurodevelopmental outcomes in infants born between 22 and 24 weeks of gestational age.
• To explore the scientific and clinical rationale for developing artificial womb technology.
• To provide an overview of the state-of-the-art in preclinical artificial womb models and analyze their neurological outcomes.

Main Methods:

• Narrative review of existing literature on extreme prematurity outcomes.
• Analysis of preclinical artificial womb models, focusing on structural, developmental, and functional neurological assessments.
• Evaluation of the limitations of current preclinical models for clinical translation.

Main Results:

• Infants born at 22-24 weeks face high risks of adverse neurological and neurodevelopmental sequelae.
• Preclinical artificial womb models demonstrate potential for supporting development, with varying degrees of success in mimicking intrauterine conditions.
• Neurological outcomes in preclinical models show promise but require further refinement to address limitations.

Conclusions:

• Artificial womb technology represents a potential paradigm shift in managing extreme prematurity.
• Further research and development of preclinical models are essential to optimize neurological outcomes before clinical application.
• Addressing the limitations of current artificial womb technology is crucial for successful clinical translation and improving survival and neurodevelopment in extremely preterm infants.
