The interstitium of the renal medulla is hypertonic, imposing deleterious effects on local cells. At the same time, the hypertonicity provides osmotic gradient for water reabsorption and is a local signal for tissue-specific gene expression and differentiation of the renal medulla, which is a critical organ for water homeostasis.
肾髓质的间质呈高渗状态,对局部细胞产生有害影响。与此同时,这种高渗性为水的重吸收提供了渗透梯度,并且是肾髓质组织特异性基因表达和分化的局部信号,而肾髓质是水稳态的关键器官。
