Extended Data Fig. 4: Transcriptional activity of Foxc1 locus in 15mo old mouse skin.
From: Escape of hair follicle stem cells causes stem cell exhaustion during aging
a, Transcriptional activity of Foxc1 locus (Foxc1-LacZ knockin) is detected in anagen bulge but not detected in telogen bulge. Scale bar, 20μm. b, Transcriptional activity of Foxc1 locus (Foxc1-LacZ knockin) is not detected in telogen bulge. Scale bar, 20μm. c, Robust transcriptional activity of Foxc1 locus (Foxc1-LacZ knockin) is detected in both bulge and IRS regions of anagen hair follicles. Scale bar, 20μm.
