Autocrine growth factor secretion has classically been considered as a mechanism by which tumour cells achieve autonomous growth. However, there is now considerable evidence that autocrine circuits operate in the growth regulation of normal adult tissues. Here we consider the possible advantages to the normal epithelial cell of utilising such an external growth factor circuit and suggest that autocrine growth factor secretion, when viewed in a multicellular context, could paradoxically form part of a mechanism for preventing tumour development.
自分泌生长因子的分泌传统上被认为是肿瘤细胞实现自主生长的一种机制。然而,现在有大量证据表明自分泌回路在正常成年组织的生长调节中发挥作用。在此,我们探讨了正常上皮细胞利用这种外部生长因子回路可能具有的优势,并提出在多细胞环境中看待自分泌生长因子的分泌时,它可能反常地成为预防肿瘤发生机制的一部分。
