(a, b) The tested protocols for renal vesicle induction. (c) Immunocytochemistry for SIX2 and LHX1 in structures on day 14 of differentiation. Transient treatment with CHIR 3 μM from day 9 to 11, in combination with FGF9 10 ng/ml from day 7 to 14, increased the number of LHX1+ cells and suppressed SIX2 expression, suggesting mesenchymal epithelial transition. Scale bars: 50 μm. REGM: renal cell growth medium (Lonza, #CC-3190).
