Figure S1. Expression patterns of nectin-1 and nectin-3 mRNA in embryonic day 17 skin. Nectin-1 is expressed in the epidermis and hair follicle while nectin-3 is not expressed in the epidermis and hair follicle at embryonic day 17.

Figure S2. Macroscopic pictures of ventral skin of control and nectin-1-/-; nectin-3+/- mice. The ventral skin of nectin-1-/-; nectin-3+/- mice exhibited reduced hair follicle than that of control mice.

Figure S3. Triple staining with antibodies against p63 and K14 and with DAPI for the nuclei in nectin-1-/-; nectin-3+/- epidermis. The cells that exhibited reduced expression of K14 are negative for p63 in nectin-1-/-; nectin-3+/- epidermis.

Figure S4. Immunohistochemical analysis of p63 and Ki67 in dorsal hair follicle of control and nectin-1-/-; nectin-3+/- skin. The remaining expression of Ki67 and p63 are observed in the nectin-1-/-; nectin-3+/-hair follicles.

Figure S5. The histological and immunohistochemical analysis of embryonic skin of control and compound mutant at embryonic day 14. The skin of nectin-1-/-; nectin-3-/- mice is comparable to that of control mice.

Figure S6. Macroscopic pictures of control and nectin-1-/-; nectin-3+/- embryo at embryocnic day 17. The gross appearance of nectin-1-/-; nectin-3+/- is comparable to that of control mice at embryonic day 17.
