- Figure 2 KROX20 protein is required for Meibomian gland development. ( A and C ) Lineage tracing in Krox20-Cre; R26-tdTomato ( Krox20-Cre; R26-Tom ) mice shows absence of KROX20 expression or Krox20 -lineage cells in the cornea (white arrows) and the limbus (green arrows). ( B ) The purple boxed region in A , which displays an image of ""P5 eye,"" is shown, with a high-magnification view of the cornea. ( C ) Immunofluorescence staining of eyeballs from Krox20-Cre;R26-Tom mice for limbus marker K15 and tdTomato (Tom). ( D ) The yellow boxed region in C , which displays an image of ""P83 eye,"" is shown, with a high-magnification view of the limbus. ( E ) H&E staining of 2.5-month-old Krox20-cKO mice shows absence of the Meibomian gland. ( F ) Immunofluorescence staining for K14 costained with PPARgamma. ( G ) Oil Red O staining showing absence of meibum in Krox20-cKO mice. ( H - J ) Immunofluorescence staining of Meibomian gland with KROX20 and K14 antibodies. Dashed lines (red in E and white in G - J ) demarcate the expected location of the Meibomian gland. n = 20 Krox20 fl/fl mice, and n = 25 Krox20-cKO mice. Among mice analyzed, 100% of Krox20-cKO mice lack the Meibomian gland. Representative images are shown. Scale bar: 100 mum.

- Figure 3 KROX20 is expressed in Meibomian gland during development and maintained throughout life. ( A ) Immunofluorescence staining of Krox20-GFP mice demonstrates KROX20 expression in the Meibomian gland at various ages. ( B ) Immunofluorescence staining for GFP (KROX20) and PPARgamma expression in Meibomian gland of P12 mice. Representative images are shown. M, months. Scale bar: 100 mum.

- Figure 5 KROX20-positive cells are indispensable for Meibomian gland development. Krox20-DTA ; K14-Cre pups (P6) in which KROX20-expressing cells were deleted exhibit complete loss of Meibomian gland, as shown by coimmunostaining for ( A ) K14 and KROX20, ( B ) H&E staining, and ( C ) K14 and PPARgamma immunostaining. ( D ) These mice also failed to produce meibum, as shown by the lack of Oil Red O staining in the eyelid. Dashed lines (red in B and D and white in A and C ) demarcate the Meibomian glands in the control mice and its expected location in the Krox20-DTA;K14-Cre mice. n = 7 K14-Cre mice, and n = 11 Krox20-DTA;K14-Cre mice. Representative images are shown. Scale bar: 100 mum.

- Figure 6 Inducible ablation of Krox20 -lineage cells in adult mice. Doxycycline-induced Krox20 -lineage cell ablation from P20 to P92 causes corneal lesions. ( A and B ) Gross images of eyes and eyeballs from rtTA-EGFP +/- ;Tet-DTA +/- ;Krox20-Cre mice and controls. The black arrow in B is pointing to the corneal lesion. ( C ) H&E staining as well as ( D ) immunofluorescence staining for K14 and PPARgamma and ( E ) K14 and KROX20 in the Meibomian glands from rtTA-EGFP +/- ; Tet-DTA +/- ; Krox20-Cre mice and controls. White dashed lines in C - E demarcate the Meibomian gland in the control mice and its expected location in the rtTA-EGFP +/- ; Tet-DTA +/- ; Krox20-Cre mice. n = 7 Krox20-DTA;K14-Cre mice, and n = 11 Krox20-DTA;K14-Cre mice. Representative images are shown. Scale bar: 100 mum.

- Figure 8 Absence of the Meibomian gland in mice lacking both Krox20 and Krox24 . ( A ) Gross images of the eye in Krox20 fl/fl (WT), Krox24 -/- ( Krox24-KO ), Krox20 fl/fl ;K14-Cre ( Krox20-cKO ), and Krox24 -/- ;Krox20 fl/fl ;K14-Cre ( DKO ) mice. ( B - F ) Histological analyses revealed the absence of the Meibomian gland (MG) in the eyelids of Krox20-cKO and DKO mice, whereas Krox24-KO and WT littermates maintained normal MG structure. Gross images in A are the same as those in Figure 7A , Supplemental Figure 1 (8M), and Supplemental Figure 2A . Dashed lines (red in B and white in C - F ) demarcate the Meibomian gland in the control mice and its expected location of the Meibomian glands in the KOs. n = 20 mice for each genotype. Representative images are shown. Scale bar: 100 mum.
