Expression of early lacrimal gland development markers in the protein and mRNA level on day 21 of differentiation confirms emergence of lacrimal gland stem and progenitor cells, (A) KRT14+/PAX6+/P63 + lacrimal gland multipotent epithelial stem cells, (B) KRT13+/P63 + lacrimal gland progenitor cells, (C) FOXC1+/PITX2+ periocular mesenchymal cells (Figures are representative of three independent differentiation experiments, scale bar: 50 µm), (D) Flow cytometry analysis of organoids with epithelial (EpCAM) and neural crest (P75) markers. N = 2 biological replicates. (E) Gene expression profile of organoids (F) miRNA 205 PCR expression and FGF10 levels during the same time course. (One-Way ANOVA. Error bars represent standard error of mean. *p ≤ .05, n = 3 biological replicates).
