Abstract:
Objective To study the clinical effects of human amniotic membrane transplantation loaded with autologons marrow mesenchymal stem cells(MSCs) in treatment of pterygium patient. Methods Totally 10 patient (10 eyes) with primary giant pterygium aged 42 ～60 years(7 males and 3 females) were enrolled. All patients were informed consents. Bone marrow was sterilely collected by bone marrow aspiration. MSCs were harvested, purified and cultured. At the third passage,MSCs were incubated in amniotic membrane. After pterygium resection,amniotic membrane patch with cells surface upward was covered on surface of exposed sclera. Another simple amniotic membrane was sutured to protect transplanted cells. Results 1 ～ 3 days after dissection of corneal epithelial area was repaired,a week around later,migration of conjunctival epithelial gradually grew,about 10 ～ 14 days, absorption and fusion of amniotic membrane began. Follow-up of 6 months to 3 years, there was no recurrence. Conclusion After amniotic membrane loaded with MSCs were transplanted to the ocular surface ,corneal epithelium repaired rapidly ,transplanted amniotic membrane and conjunctival integrated, conjunctival irritation was few, ocular surface scar was light, the pterygium was no recurrence.
