Figure 7. Reduced progenitor marker expression in p63+/L514F and Fgfr2b−/− mice and in skin of AEC patients.
- Immunostaining reveals reduced Krt15 expression (green) in the epidermis and in the hair follicle of p63+/L514F and Fgfr2b−/− compared to +/+ control. Nuclei are stained with DAPI. Scale bar: 50 µm.
- Immunoblotting for Krt15 confirms decreased protein expression in p63+/L514F epidermis compared to +/+. Tubulin was used to normalize samples.
- Immunostaining for Krt15 (green) of skin biopsies from AEC patients (AEC1 and AEC2) and a human unaffected control (CTR) demonstrates reduced Krt15 expression in AEC skin. Scale bar: 50 µm.
- Real-time RT-PCR for Krt15 mRNA in human skin isolated from AEC patients or controls (CTR) reveals a quantitative reduction of Krt15 mRNA levels in the skin of AEC patients compared to wild-type. Data are represented as mean ± SD (p-value = 0.026).
- Immunofluorescence for Sox9 on neonatal mouse skin reveals reduced Sox9 expression in p63+/L514F and Fgfr2b−/− compared to +/+ control. Scale bar: 50 µm.
- Levels of Sox9 mRNA in human skin isolated from AEC patients or controls (CTR) were assessed by real-time RT-PCR. Data are represented as mean ± SD (p-value = 3.85 × 10−5).
