ABSTRACT

Epidermal growth factor (EGF) is a polypeptide growth factor, which stimulates cellular division, migration and differentiation. A number of in vivo models have extensively documented that EGF is involved in embryonic, fetal and neonatal development, differentiation and maturation. Other evidences clearly show that EGF is a fundamental growth factor in maintaining tissue morphology and physiology in adult organisms, whereas it seems to participate in cytoprotection, cellular population renewal and in epithelial healing. Some data suggest that the parenteral administration of EGF in pharmacological concentrations provokes effects that may be significantly beneficial to prevent or treat visceral organic pathologies. As preclinical results conducted so far suggest that EGF does not initiate malignant transformation, its parenteral use for acute disorders or life-threatening conditions is likely to be useful on the basis of an individual benefit-risk ratio in patients.

Key words: EGF, physiology, pharmacology, parenteral

RESUMEN

El factor de crecimiento epidérmico (FCE) estimula eventos mitóticos, motogénicos y diferenciativos en células que expresan su receptor. Numerosos datos ilustran la participación del FCE en el desarrollo embrionario, fetal y la maduración neonatal. En organismos adultos el FCE parece estar involucrado en el recambio de poblaciones epiteliales, en la citoprotección y en la cicatrización de algunos tejidos ulcerados. La administración parenteral de FCE en concentraciones farmacológicas, provoca significativas respuestas tisulares que pueden ser más extensamente explotadas en el orden terapéutico, para prevenir o tratar daños morfofuncionales internos. El hecho de que las pruebas preclínicas efectuadas hasta ahora, muestren que el FCE no inicia transformación maligna, argumenta la posibilidad de emplear este polipéptido por via parenteral, en patologías de curso agudo o de pronóstico crítico sobre la base del análisis del radio riesgo-beneficio en cada paciente.

Palabras claves: FCE, fisiología, farmacología, parenteral
