(a) The average total cell and (b) LRCs that express either SOX9, BLIMP1, or CK6 in the meibomian gland (blue) or hair follicle (orange). (c–h) Immuno-staining of meibomian gland (c, e, and g—encircled white), hair follicle (d, f, and h—encircled yellow), and sebaceous gland (f*—encircled red) showing co-localization of quiescent epithelial LRCs with (c and d) SOX9, (e and f), BLIMP1, and (g and h) CK6 in the H2B-GFP/K5tTA mouse after 56-day doxycycline chase. Scale bar =50 μm.
