These independently discovered proteins were eventually demonstrated to be the same sets of molecules, namely FGF1, HBGF-1 and ECGF-1 were all the same acidic fibroblast growth factor described by Gospodarowicz, et al., while FGF2, HBGF-2, and ECGF-2 were all the same basic fibroblast growth factor.
Estas proteínas descubertas independentemente demostrouse finalmente que eran o mesmo conxunto de moléculas, concretamente FGF1, HBGF-1 e ECGF-1 eran todas elas o mesmo factor de crecemento de fibroblastos ácido descrito por Gospodarowicz, et al., mentres que FGF2, HBGF-2 e ECGF-2 eran todas o mesmo factor de crecemento de fibroblastos básico.
