求翻译：与同一受体结合，发挥类似的生物学活性，在细胞的增殖、分化、ECM的产生、生长发育及机体的免疫功能的调节中发挥重要的作用，其中TGF-β1与纤维化关系最为密切是什么意思？

With the same receptors, play a similar biological activity in cell proliferation, differentiation, ECM production, growth and regulation of immune function play an important role in TGF-β1 and fibrosis which most closely

With the same receptor, play a similar biological reactive, in cellular proliferation, differentiation, ECM are generated, and organisms grow and develop in the immune function by the play an important role, which TGF - Beta 1 most closely related with fibrosis

With the identical acceptor union, displays the similar biology activeness, in the cell multiplication, splits up, the ECM production, the growth growth and in organism immunity function adjustment plays the vital role, in which TGF-β 1 and the fibrosis relations is closest

The same receptor binding, playing a similar biological activity, cell proliferation, differentiation, and ECM formation, growth and organism play an important role in regulation of immune function of, of which TGF-beta 1 and fibrosis is most closely related
