Culture media significantly impedes branching morphogenesis inside the kidney, but not lungUsing an organ explant culture program, murine E12 fetal kidneys and lungs had been grown inside the presence or absence of varying concentrations of NaCl or option osmolytes recognized to cross (e.g. urea) or not cross (e.g. mannitol) plasma membranes. When grown in NaCl for two days, development of murine fetal kidneys was lowered at 25 mM NaCl (Figure 1B) but markedly blunted at 50 mM (Figure 1D,K) and efficiently arrested at one hundred mM (Figure 1F). The osmotic pressure exerted by NaCl is double its molar concentration suggesting that at 125 mM NaCl, or perhaps a 2550 mosmolekg enhance in NaCl inside the culture media, is sufficient to lower branching morphogenesis in the building kidney (Figure 1K). In order to separate an osmotic from a direct effect of Na per se, we cultured organ explants inside the presence of either mannitol or urea at one hundred mosmoleskg. At one hundred mosmoleskg, andTable 1.

A 24 h urine collection with paired blood sample enabled evaluation of renal function. Osmolarity, creatinine and electrolytes were measured by an osmometer (Osmomat 030, Gonotec), auto-analyser (RX-IMOLA, Randox) and ICP-MS (XSeries II, Thermo Fisher, Ltd), respectively.
