Fetal surgery and stem cell therapy for meningomyelocele

Area of Science:

• Maternal-fetal medicine
• Regenerative medicine
• Surgical innovation

Background:

• Fetal meningomyelocele (fMMC) presents significant prenatal management challenges.
• Advances in imaging allow for more accurate in utero assessment of fMMC.
• Prenatal interventions aim to improve postnatal outcomes and minimize fetal and maternal risks.

Purpose of the Study:

• To review advancements in maternal-fetal surgery for fMMC.
• To explore the role of stem cell transplantation and tissue engineering in prenatal management.
• To synthesize current research on improving outcomes for fMMC.

Main Methods:

• Review of current literature on maternal-fetal surgery techniques for fMMC.
• Analysis of research on stem cell therapy (TRASCET) and tissue engineering approaches.
• Evaluation of imaging, surgical, and regenerative strategies.

Main Results:

• Prenatal maternal-fetal surgery for fMMC demonstrates favorable postnatal outcomes.
• Minimally invasive and endoscopic fetal surgery techniques are evolving, with comparable outcomes to open procedures.
• Trans-amniotic stem cell therapy and fetal tissue engineering show potential for spinal cord regeneration in animal models.
• Single-layer closure is preferred for fMMC repair to reduce complications.

Conclusions:

• Endoscopic fetal surgery combined with trans-amniotic stem cell therapy or tissue engineering offers a promising future for prenatal fMMC intervention.
• Ethical considerations are paramount in planning maternal-fetal surgeries to minimize morbidity.
• Further research into regenerative approaches is crucial for managing large fMMC defects.
