Basic Fibroblast Growth Factor-releasing Polyglycolic Acid Duras Improve Neurological Function after Cerebral...

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Neuroscience

Background:

• Stem cell therapy for cerebral infarction is promising but faces challenges like cost and delivery optimization.
• Bioabsorbable artificial dura mater made from Polyglycolic Acid (PGA) fabric is clinically used for cerebral infarction.
• Basic Fibroblast Growth Factor (bFGF) shows potential for treating cerebral infarctions.

Purpose of the Study:

• To prepare a bFGF-releasing PGA dura mater.
• To evaluate the therapeutic efficacy of this bFGF-releasing PGA dura mater in a mouse model of focal cerebral infarction.

Main Methods:

• Oxygen plasma treatment and bFGF adsorption were used to create the bFGF-releasing PGA dura mater.
• In vitro bFGF release was quantified using ELISA.
• The material was implanted in mice with induced cerebral infarction, followed by neurological and histological assessments.

Main Results:

• The PGA dura mater demonstrated dose-dependent bFGF release.
• Significant neurological function improvement was observed in bFGF-treated groups compared to controls.
• Increased neural progenitor cells and a trend towards enhanced angiogenesis were noted in bFGF-treated mice.

Conclusions:

• bFGF-releasing PGA dura mater effectively improved neurological function in a mouse model of focal cerebral infarction.
• This approach offers a potentially practical and effective therapeutic strategy for cerebral infarction recovery.
