From: Keratin 6 is not essential for mammary gland development
Keratin 6a (K6a) is the predominant isoform expressed in the mammary gland. Antibodies that recognize either the K6a or K6b/hf isoform were used to immunostain sections from either E16.5 embryonic mammary buds (a,b), terminal end buds (TEBs) from 6-week FVB mouse mammary glands (c,d) or hair follicles (e,f). K6a stained the mammary bud and body cells of the TEB as well as the hair follicle, but Kb6/hf was detected only in the hair follicle. Scale bar, 50 μm.
