Br J Ohthalmol Another option is the implantation of ex vivo culture stem cells on amniotic membrane support The implications pterigion tratamiento the p53 gene mutation is that LESC grow uncontrolled 14migrate and grow onto the cornea through pterigion tratamiento basal membrane 15dragging along conjunctival cells and inducing the formation of fibrovascular tissue at this level, due to increased levels of inflammatory pterigion tratamiento, proliferative and angiogenic pterigion tratamiento, such as found in the histopathologic and histochemical analysis Histochemical studies pterigion tratamiento molecular biology show that in the pterygium, the LESC Limbal Epithelial Stem Cells express a mutated tumour suppressor gene that causes the presence of protein p53 11,12a common marker in various human cancers and pterigion tratamiento lesions of actinic skin 13which suggests that pterygium would be a proliferative disorder similar to a tumour.
At an intraoperative level, it is advisable to apply drugs that inhibit fibroblast proliferation, such as Mitomycin C. Mona Harissi-Dagher and Kathryn Colby. Imnunohistochemical study of p53, p21 and PCNA in pterygium. Muchos de ellos desaparecen con el tiempo y no son tan molestos.

Perhaps today the most recommended step in preventing recurrence or when it has hardly started would be the VEGF inhivitors pterigion tratamiento in the danger zone In recent years, pterigion tratamiento observed an increase in the incidence of pterygium, both primary pterigion tratamiento recurrent.
Hence, we shall stress to the patients to avoid this type of radiation, either by reducing their exposure to sunlight or using good quality wrap-around sunglasses that have the right UV filter.
If possible, it is also better to use a conjunctival graft of the pterigion tratamiento eye, taken from the superior bulbar conjunctiva.

The UV light act on the LESC causing mutation in the gene responsible for the p53 protein synthesis, trstamiento gene loses its ability to act as a transcription factor, resulting in uncontrolled cell proliferation and pterigion tratamiento change to the signals that activate growth factors and the cyclins D1-Cdk4 11, Once the abnormal tissue is removed, the possibility of suturing the edges of the healthy conjunctiva must be considered.
Review ptergiion treatmen of pterygium in Queensland, 10 years pterigion tratamiento primary surgery.
